Bitcoin (BTC) Real-Time Price Index and Chart — CoinDesk 20

This graph shows Bitcoin price and volume (ie, blocksize of transactions on the blockchain) rising hand-in-hand in 2011-2014. In 2015, Core/Blockstream tried to artificially freeze the blocksize - and artificially froze the price. Bitcoin Classic will allow volume - and price - to freely rise again.

The graph below tells you everything you need to know about the way that Bitcoin price and volume normally always move in lockstep, tightly correlated with each other - until Blockstream tragically tried to interfere starting around 2015:

How We Know Bitcoin Is Not a Bubble

(Scroll down to see the graph - also note there is a typo in the legend: "Bitcoin market map" should say "Bitcoin market cap[italization]".)
Without artificial limits, Bitcoin volume and price are naturally and tightly correlated.
This tight, lockstep correlation between those two lines during 2011-2014 has been absolutely amazing - one of the tightest correlations you'll ever observe in any dynamic system anywhere, in economics, sociology, or nature.
Price and volume rose (and fell) hand-in-hand for 4 years straight - one of the most majestic examples of emergent phenomena in the whole history of economics.
Left to run its natural course, this graph would probably have continued in lockstep, and thus would have eventually gone into the history books of future generations, marking the inexorable emergence and dominance of the cryptocurrency known as Bitcoin - the inevitable triumph of humanity's first decentralized and permissionless store of value, medium of exchange, and unit of account - steadily rising through the years in price and volume - and in usefulness.
Then in late 2014, a new company called Blockstream tried to block this natural progression.
The oligarchs behind the ancien régime of debt-backed, violence-enforced infinite fiat thought they had figured out a clever way to attempt to make their last pièce de résistance while making some money too.
They brought out their their usual grab-bag of assorted dirty tricks which they typically use to take down any new social or economic or political movement that promises to liberate people from the stranglehold of private central bankers:
So far, Blockstream thinks they're winning in their battle to control Bitcoin.
  • They succeeded (during 2015) in splitting the community, maybe even creating even a few more useful idiots in the process.
  • They succeeded (during 2015) in suppressing the price: as you can see by observing how the lockstep correlation between price and volume diverged in 2015, with the price now lagging and sagging below the volume for the first time ever.
https://imgur.com/jLnrOuK
But can they keep spreading around their fiat and FUD to continue fooling all the people all the time?
Probably not. Because...
Now you can choose to run a repo without Blockstream's artificial scarcity on blocksize and transactions on the blockchain.
Now, instead of running the Bitcoin Core repo from Blockstream, you can run any one of these another tested and deployed repos, which do not artificially limit the blocksize to 1 MB:
Bitcoin is a natural, market-based and community-based, emergent phenomenon.
At its heart, in the words of Satoshi Nakamoto, Bitcoin is a P2P Electronic Cash System where Alice "A" can send to Bob "B" some amount of Coins "C", secured via a cryptographic signature.
It may come as a shock to certain people's egos, but even if most of the devs were to suddenly stop working now - the current system would probably work fine for the next few years - with investors and businesspeople continuing to gradually increase the price and volume in accordance with the desires of the worldwide market, and miners and full-nodes continuing to gradually increase the "max blocksize" in accordance with the capacity of the worldwide infrastructure - and everyone continuing to innovate and participate in the growth of the system in accordance with the desires of the worldwide community.
Bitcoin doesn't really need a whole lot of interference from devs trying to centrally plan what the "max blocksize" should be - or mods trying to centrally control what the "consensus of opinions" should be. These kinds of things are better left to just naturally emerge on their own.
Central planning and control are not needed.
As we have already seen, when the market is allowed to determine Bitcoin price and volume on its own, they both naturally go up, hand-in-hand - while the value of centrally-planned fiat goes down and and down.
And when the community is allowed to determine upvotes and downvotes on its own, the quality of debate naturally goes up - while the quality of centrally-controlled debate on censored forums goes down and down.
We all know that Bitcoin is supposed to be trustless and permissionless.
Bitcoin development should also be egoless.
As a dev or a mod, it's hard to "step aside" and let the market or the community decide. It's much more tempting to interfere: enforce a limit here, delete a comment there.
But the market and the community are emergent phenomena. They work best when devs and mods learn to put aside their egos and "step back" and let the market and the community do what they will.
This is the raison d'être of Bitcoin Classic, Bitcoin Unlimited, and Bitcoin XT: learning to let the market and the community decide again - learning to step back again, and let the price and volume go up again, with no unnecessary interference from devs or mods.

Bitcoin price vs volume graph for 2011-2016 suggests: (1) MtGox/Willy made price overshoot in late 2013; (2) Blockstream is making price undershoot since late 2014. This is easy to test, by sticking with Satoshi's plan. Anyone who opposes this test is anti-science, anti-markets - and anti-investors!

https://imgur.com/jLnrOuK
If you look at this graph, you will notice:
If you look really close, you'll also be tempted to formulate a rough estimate that:
So, if the correlation in this graph had continued (ie, if Blockstream / Core hadn't started attempting to artificially suppress the blocksize, since their launch in November 2014), then 1 BTC would equal over 2,000 USD now.
You can shout "correlation isn't causation!!!" all you want.
All I am saying is: let's test it out.
Let's allow the actual blocksize to continue to increase like it has been doing for the past few years - un-impeded by any artficial blocksize limit.
Let's follow Satoshi's plan (where the price increased with the volume) and not Core / Blockstream's plan (where the volume is rising and hitting an artificial limit, and the price has been stagnating).
We can easily test hypothesis (2) in the title of the OP (the claim that "Core / Blockstream is suppressing the price by suppressing the blocksize"), by simply increasing (or removing) the temporary artificial blocksize limit, thus allowing the natural blocksize to continue to grow unrestrained - and observing whether price and volume continue to grow together.
This is what Satoshi wanted. Since he was right about everything else, we should do what he wants now.
Those who would deny us the chance to continue this experiment (Core / Blockchain) are anti-science, anti-markets - and anti-investors.

Is bitcoin really un-tethered? this paper looks at the btc / tether connection; it examines if tether is not back by dollars and is printed to pump prices mainly btc

here is the paper, its quite long but a good read. below ive added some quotes. If you read this paper it will likely just confirm want most who have been in this space for a while think about tether, its centralised with no accountability and is likely not backed 1:1 and is likely an instrument to pump / manipulate prices most noteably bitcoin.
Is Bitcoin Really un-tethered?
some snippets from the paper:
flow of tether between exchanges, the main players:
Figure 1 plots the aggregate flow of Tether among major market participants on the Tether blockchain from its conception in October 6, 2014 until March 31, 2018. The size of the nodes is proportional to the sum of coin inflow and outflow to each node, the thickness of the lines is proportional to the size of flows, and all flow movements are clockwise. Tether is authorized, moved to Bitfinex, and then slowly distributed to other Tether-based exchanges, mainly Poloniex and Bittrex. The graph shows that almost no Tether returns to the Tether issuer to be redeemed, and the major exchange where Tether can be exchanged for USD, Kraken, accounts for only a small proportion of transactions. Tether also flows out to other exchanges and entities and becomes more widespread over time as a medium of exchange.
A similar analysis of the flow of coins on the much larger Bitcoin blockchain shows that the three main Tether exchanges for most of 2017 (Bitfinex, Poloniex, and Bittrex) also facilitate considerable cross-exchange Bitcoin flows among themselves.6 Additionally, we find that the cross-exchange Bitcoin flows on Bitcoin blockchain closely matches the Tether flows on Tether blockchain.
a large player is likely responsiblle for a lot of this:
we find that one large player is associated with more than half of the exchange of Tether for Bitcoin at Bitfinex, suggesting that the distribution of Tether into the market is from a large player and not many different investors bringing cash to Bitfinex to purchase Tether
people who worked on the inside even admit tether isnt backed 1:1
in response to legal motions, on April 30, 2019, Bitfinex’s former General Counsel admitted that Tether does not have cash reserves equal to 100% of the outstanding Tethers. In a May 15, 2019 court hearing, a Bitfinex attorney also admitted that Tether did invest in instruments beyond cash, including Bitcoin, something clearly at odds with Tether’s longstanding claims.

$1B Bitcoins On The Move: Owner Transfers ~$100M to Bitfinex And Binance In 10 Days

$1B Bitcoins On The Move: Owner Transfers ~$100M to Bitfinex And Binance In 10 Days
This is the third post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
The origin of the bitcoins is discussed here.
A deep-dive into the wallet activity was discussed here.
Today, I will focus on the transfer to major exchanges wallets that could indicate that the owner is selling his coins or exchanging it with alts or mixing it to cover his back.
I built a graph in order to deep dive into the transactions originated from the 111,114-BTC wallet and to follow it. This is the resulting graph were red indicates transactions <1 day, yellow <1 month, blue <1 year, green else.
https://preview.redd.it/nk3iov045vj11.png?width=1677&format=png&auto=webp&s=176d5b5bda930abf870dbea7edd1ba5b654158be

I found that at least 15,593 BTC originated from the 111,114-BTC wallet have been moved to Bitfinex and Binance wallets. This represents 14% of the original funds and more than $110M.

Bitfinex wallet

11,114 BTC have been transferred to Bitfinex wallet 1Kr6QSydW9bFQG1mXiPNNu6WpJGmUa9i1g and the majority of these coins have been transferred in the last 7 days (August 24th - September 2nd).
Here is the list of the transactions:

Bitmex wallet(s)

I tracked Bitmex as well but "only" found 210 BTC transferred in with the following 6 major transactions:

Update 1
If anyone finds if the owner of this address is an exchange : 3PtJRj5xKUKJ21TshP5u2G6dQMPNz2yUSc, I would be interested, thanks.

Update 2
Here is a full resolution version of the graph requested by u/rush717:

Update 3
MtGox vs SilkRoad origin and September 6th BTC price impact is now discussed here: https://www.reddit.com/btc/comments/9dvaj1b_bitcoins_on_the_move_mtgox_vs_silkroad_origin/

--
Surprisingly BTC price was pumping since those funds were starting to be transferred to Bitfinex and Binance wallets (see Binance transactions' list, August 11th)
How do you think this will impact the market?
Do you want me to continue this investigation? If yes let me know what you would want me to focus on.

Linear Regression following Sentdex's tutorials

Hello. I am trying to do some machine learning on some bitcoin data, specifically linear regression. The full code is here, but in order to plot it on a graph, I want to use the values of y (which is the values of x in 14.5 days time, so price in 14.5 days time) where I use the old actual values of y followed by the new values of y which are the predictions. In order to do this I need to find the values of X which have values for y (the predictions) and the values for x which already have the price in 14.5 days time. I performed a shift on the data, meaning some Xs have values for Y in 14.5 days time and some don't.
Why 14.5 days? As the data set is 1450 days long and I did a 0.01 negative shift. Hopefully I communicated what I was trying to say alright.
import pandas as pd import math import numpy as np from sklearn import preprocessing, svm from sklearn.model_selection import cross_validate from sklearn.model_selection import train_test_split from sklearn.linear_model import LinearRegression from statistics import mean import matplotlib.pyplot as plt from matplotlib import style df = pd.read_csv("coinbaseUSD_1-min_data_2014-12-01_to_2019-01-09.csv") df['date'] = pd.to_datetime(df['Timestamp'],unit='s').dt.date print("calculating...") forecast_col = 'Weighted_Price' forecast_out = int(math.ceil(0.01*len(df))) #forecast_out = 20998 = 20998 minutes = 14.5 days df['label'] = df[forecast_col].shift(-forecast_out) df = df[['date', 'Weighted_Price', 'label']] df.dropna(inplace=True) X = np.array(df['Weighted_Price'], dtype = np.float64) y = np.array(df['label'], dtype=np.float64) X_lately = X[-forecast_out:] X = X[:-forecast_out:] def best_fit_line(X, y): m = (((mean(X) * mean(y)) - mean(X*y)) / ((mean(X) * mean(X)) - mean(X*X))) c = mean(y) - (m * (mean(X))) return m, c m, c = best_fit_line(X, y) print(m, c) regression_line = [(m*values) for values in X] plt.scatter(X, y) plt.plot(X, regression_line) plt.show()

So what have I tried? The offender is this line here:
X_lately = X[-forecast_out:] X = X[:-forecast_out:]
That is what sentdex did in the video series, but I get the error: ValueError: operands could not be broadcast together with shapes (1871868,) (1892866,)
This doesn't work with:
m = (((mean(X) * mean(y)) - mean(X*y)) / ((mean(X) * mean(X)) - mean(X*X)))
due to this making the X and Ys different lengths? I'm not sure.
What am I doing wrong?

Rainbow price charts needed to be adjusted - still bullish AF obviously

In summer 2014, this chart was posted.
The summer 2016 version looks like this.
 
First chart indicated July 2014 as strong buy. Second chart tells us in classic hindsight fashion that July 2014 was a very strong sell. Wait, you bought at this point? Silly you.

This room feels like Q4 2016 all over again

This isn't a pump piece but more of an observations piece.
Does anyone feel like this is Q4 2016 all over again? I'm talking about price and sentiment here in this sub specifically when we had less than 5000 members. I'm probably not going to get a lot of old timers to chime in here but our numbers have gone 10x+ in terms of members and everything is magnified.
The main difference this time pricewise is we're fighting for $1000 instead of $10. Just reading everything on Reddit yesterday with laughncow crash graph comments reminds me of the troll winter here in EthTrader back in Q4 2016....lots of long timers were starting bailing out because they'd never seen a crash before that big. MANY MANY people bought at the high range $18-$22 (yes including me) and were capitulating under $12 hoping to get back in around $3 "because they'd seen it in Bitcoin before". And then the reversal took place at $5.85....so my mind thinks the market wants to see yet a 3rd dip to $585 to complete the painting of the tape. I will not dare sell here. So be it if it does.
"um..guys are we gonna be like 2014 400 day long bear again?"..."guys are we?"
When I here this fear I get the feeling that someone over invested. Don't over-invest. I made that mistake in that particular year. You can use risky money if you are younger but PLEASE don't use emergency money. One unforeseen medical bill forced my hand to sell at a loss that year. PLEASE don't use emergency money like I did.
Now fundamentals have improved dramatically in terms of conference attendance, community participation, EEA, truffle use, DAPPS going through final audits/testing, OMG plasma in May along with a whole new wave media/gov/companies everywhere piling in the space and concern trolls are really truly worried we may revisit $100 again. REALLY?
"I'll be back in when we complete the retrace to $100-$200. I hate to see $300 break but it may" blah blah blah.
I know I'm a man of many rose colored glasses. There are ALWAYS going to politics and regulation fears in crypto. Just get it in your head that crypto is here to stay. The US at least is wanting your tax dollars any way they can and crypto is no longer something that has a fear of being wiped (which it can't anyway but that's a different philosophy thread) but rather being considering a BOOMING new asset class. An asset class that has proven to be a very low barrier to entry asset class with much to prove in terms of utility and trustless settlements.
You can buy now, buy later, sell now, sell later. 4 choices. I personally think the band-aid is off and the next move up may leave you the way the reversal left so many traders at the station Q1 2017 particularly in April 2017. Traders back then who had sold at $10 never reentered because the price hit $50 and was still "overvalued". Now here we are just just under the new $7 in my book.
I'm beginning to think market makers are holding a lower ceiling here and the higher lows are coming. I can feel it. Bitcoin needs to shit the bed one more time and let the strong hands go deep in around $7500, ETH ratio holds/goes higher here, we touch $550-$625 or so and then the train leaves the good gosh golly darn station again. No problem doing some DCA here. Just some thoughts.
Project to January 2020 for a bit. What do you see?

Beginner’s Guide to BitMEX

Beginner’s Guide to BitMEX

Founded by HDR Global Trading Limited (which in turn was founded by former bankers Arthur Hayes, Samuel Reed and Ben Delo) in 2014, BitMEX is a trading platform operating around the world and registered in the Seychelles.
Meaning Bitcoin Mercantile Exchange, BitMEX is one of the largest Bitcoin trading platforms currently operating, with a daily trading volume of over 35,000 BTC and over 540,000 accesses monthly and a trading history of over $34 billion worth of Bitcoin since its inception.

https://preview.redd.it/coenpm4k3cc41.jpg?width=808&format=pjpg&auto=webp&s=8832dcafa5bd615b511bbeb6118ef43d73ed785e
Unlike many other trading exchanges, BitMEX only accepts deposits through Bitcoin, which can then be used to purchase a variety of other cryptocurrencies. BitMEX specialises in sophisticated financial operations such as margin trading, which is trading with leverage. Like many of the exchanges that operate through cryptocurrencies, BitMEX is currently unregulated in any jurisdiction.
Visit BitMEX

How to Sign Up to BitMEX

In order to create an account on BitMEX, users first have to register with the website. Registration only requires an email address, the email address must be a genuine address as users will receive an email to confirm registration in order to verify the account. Once users are registered, there are no trading limits. Traders must be at least 18 years of age to sign up.
https://preview.redd.it/0v13qoil3cc41.jpg?width=808&format=pjpg&auto=webp&s=e6134bc089c4e352dce10d754dc84ff11a4c7994
However, it should be noted that BitMEX does not accept any US-based traders and will use IP checks to verify that users are not in the US. While some US users have bypassed this with the use of a VPN, it is not recommended that US individuals sign up to the BitMEX service, especially given the fact that alternative exchanges are available to service US customers that function within the US legal framework.
How to Use BitMEX
BitMEX allows users to trade cryptocurrencies against a number of fiat currencies, namely the US Dollar, the Japanese Yen and the Chinese Yuan. BitMEX allows users to trade a number of different cryptocurrencies, namely Bitcoin, Bitcoin Cash, Dash, Ethereum, Ethereum Classic, Litecoin, Monero, Ripple, Tezos and Zcash.
The trading platform on BitMEX is very intuitive and easy to use for those familiar with similar markets. However, it is not for the beginner. The interface does look a little dated when compared to newer exchanges like Binance and Kucoin’s.
Once users have signed up to the platform, they should click on Trade, and all the trading instruments will be displayed beneath.
Clicking on the particular instrument opens the orderbook, recent trades, and the order slip on the left. The order book shows three columns – the bid value for the underlying asset, the quantity of the order, and the total USD value of all orders, both short and long.
The widgets on the trading platform can be changed according to the user’s viewing preferences, allowing users to have full control on what is displayed. It also has a built in feature that provides for TradingView charting. This offers a wide range of charting tool and is considered to be an improvement on many of the offering available from many of its competitors.
https://preview.redd.it/fabg1nxo3cc41.jpg?width=808&format=pjpg&auto=webp&s=6d939889c3eac15ab1e78ec37a8ccd13fc5e0573
Once trades are made, all orders can be easily viewed in the trading platform interface. There are tabs where users can select their Active Orders, see the Stops that are in place, check the Orders Filled (total or partially) and the trade history. On the Active Orders and Stops tabs, traders can cancel any order, by clicking the “Cancel” button. Users also see all currently open positions, with an analysis if it is in the black or red.
BitMEX uses a method called auto-deleveraging which BitMEX uses to ensure that liquidated positions are able to be closed even in a volatile market. Auto-deleveraging means that if a position bankrupts without available liquidity, the positive side of the position deleverages, in order of profitability and leverage, the highest leveraged position first in queue. Traders are always shown where they sit in the auto-deleveraging queue, if such is needed.
Although the BitMEX platform is optimized for mobile, it only has an Android app (which is not official). There is no iOS app available at present. However, it is recommended that users use it on the desktop if possible.
BitMEX offers a variety of order types for users:
  • Limit Order (the order is fulfilled if the given price is achieved);
  • Market Order (the order is executed at current market price);
  • Stop Limit Order (like a stop order, but allows users to set the price of the Order once the Stop Price is triggered);
  • Stop Market Order (this is a stop order that does not enter the order book, remain unseen until the market reaches the trigger);
  • Trailing Stop Order (it is similar to a Stop Market order, but here users set a trailing value that is used to place the market order);
  • Take Profit Limit Order (this can be used, similarly to a Stop Order, to set a target price on a position. In this case, it is in respect of making gains, rather than cutting losses);
  • Take Profit Market Order (same as the previous type, but in this case, the order triggered will be a market order, and not a limit one)
The exchange offers margin trading in all of the cryptocurrencies displayed on the website. It also offers to trade with futures and derivatives – swaps.

Futures and Swaps

A futures contract is an agreement to buy or sell a given asset in the future at a predetermined price. On BitMEX, users can leverage up to 100x on certain contracts.
Perpetual swaps are similar to futures, except that there is no expiry date for them and no settlement. Additionally, they trade close to the underlying reference Index Price, unlike futures, which may diverge substantially from the Index Price.
BitMEX also offers Binary series contracts, which are prediction-based contracts which can only settle at either 0 or 100. In essence, the Binary series contracts are a more complicated way of making a bet on a given event.
The only Binary series betting instrument currently available is related to the next 1mb block on the Bitcoin blockchain. Binary series contracts are traded with no leverage, a 0% maker fee, a 0.25% taker fee and 0.25% settlement fee.

Bitmex Leverage

BitMEX allows its traders to leverage their position on the platform. Leverage is the ability to place orders that are bigger than the users’ existing balance. This could lead to a higher profit in comparison when placing an order with only the wallet balance. Trading in such conditions is called “Margin Trading.”
There are two types of Margin Trading: Isolated and Cross-Margin. The former allows the user to select the amount of money in their wallet that should be used to hold their position after an order is placed. However, the latter provides that all of the money in the users’ wallet can be used to hold their position, and therefore should be treated with extreme caution.

The BitMEX platform allows users to set their leverage level by using the leverage slider. A maximum leverage of 1:100 is available (on Bitcoin and Bitcoin Cash). This is quite a high level of leverage for cryptocurrencies, with the average offered by other exchanges rarely exceeding 1:20.

BitMEX Fees

For traditional futures trading, BitMEX has a straightforward fee schedule. As noted, in terms of leverage offered, BitMEX offers up to 100% leverage, with the amount off leverage varying from product to product.
However, it should be noted that trading at the highest leverages is sophisticated and is intended for professional investors that are familiar with speculative trading. The fees and leverage are as follows:
https://preview.redd.it/wvhiepht3cc41.jpg?width=730&format=pjpg&auto=webp&s=0617eb894c13d3870211a01d51af98561907cb99

However, there are additional fees for hidden / iceberg orders. A hidden order pays the taker fee until the entire hidden quantity is completely executed. Then, the order will become normal, and the user will receive the maker rebate for the non-hidden amount.

Deposits and Withdrawals

BitMEX does not charge fees on deposits or withdrawals. However, when withdrawing Bitcoin, the minimum Network fee is based on blockchain load. The only costs therefore are those of the banks or the cryptocurrency networks.
As noted previously, BitMEX only accepts deposits in Bitcoin and therefore Bitcoin serves as collateral on trading contracts, regardless of whether or not the trade involves Bitcoin.
The minimum deposit is 0.001 BTC. There are no limits on withdrawals, but withdrawals can also be in Bitcoin only. To make a withdrawal, all that users need to do is insert the amount to withdraw and the wallet address to complete the transfer.
https://preview.redd.it/xj1kbuew3cc41.jpg?width=808&format=pjpg&auto=webp&s=68056f2247001c63e89c880cfbb75b2f3616e8fe
Deposits can be made 24/7 but withdrawals are processed by hand at a recurring time once per day. The hand processed withdrawals are intended to increase the security levels of users’ funds by providing extra time (and email notice) to cancel any fraudulent withdrawal requests, as well as bypassing the use of automated systems & hot wallets which may be more prone to compromise.

Supported Currencies

BitMEX operates as a crypto to crypto exchange and makes use of a Bitcoin-in/Bitcoin-out structure. Therefore, platform users are currently unable to use fiat currencies for any payments or transfers, however, a plus side of this is that there are no limits for trading and the exchange incorporates trading pairs linked to the US Dollar (XBT), Japanese Yen (XBJ), and Chinese Yuan (XBC).
BitMEX supports the following cryptocurrencies:
  • Bitcoin (XBT)
  • Bitcoin Cash (BCH)
  • Ethereum (ETH)
  • Ethereum Classic (ETC)
  • Litecoin (LTC)
  • Ripple Token (XRP)
  • Monero (XMR)
  • Dash (DASH)
  • Zcash (ZEC)
  • Cardano (ADA)
  • Tron (TRX)
  • EOS Token (EOS)
BitMEX also offers leverage options on the following coins:
  • 5x: Zcash (ZEC)
  • 20x : Ripple (XRP),Bitcoin Cash (BCH), Cardano (ADA), EOS Token (EOS), Tron (TRX)
  • 25x: Monero (XMR)
  • 33x: Litecoin (LTC)
  • 50x: Ethereum (ETH)
  • 100x: Bitcoin (XBT), Bitcoin / Yen (XBJ), Bitcoin / Yuan (XBC)

Trading Technologies International Partnership

HDR Global Trading, the company which owns BitMEX, has recently announced a partnership with Trading Technologies International, Inc. (TT), a leading international high-performance trading software provider.
The TT platform is designed specifically for professional traders, brokers, and market-access providers, and incorporates a wide variety of trading tools and analytical indicators that allow even the most advanced traders to customize the software to suit their unique trading styles. The TT platform also provides traders with global market access and trade execution through its privately managed infrastructure and the partnership will see BitMEX users gaining access to the trading tools on all BitMEX products, including the popular XBT/USD Perpetual Swap pairing.

The BitMEX Insurance Fund

The ability to trade on leverage is one of the exchange’s main selling points and offering leverage and providing the opportunity for traders to trade against each other may result in a situation where the winners do not receive all of their expected profits. As a result of the amounts of leverage involved, it’s possible that the losers may not have enough margin in their positions to pay the winners.
Traditional exchanges like the Chicago Mercantile Exchange (CME) offset this problem by utilizing multiple layers of protection and cryptocurrency trading platforms offering leverage cannot currently match the levels of protection provided to winning traders.
In addition, cryptocurrency exchanges offering leveraged trades propose a capped downside and unlimited upside on a highly volatile asset with the caveat being that on occasion, there may not be enough funds in the system to pay out the winners.
To help solve this problem, BitMEX has developed an insurance fund system, and when a trader has an open leveraged position, their position is forcefully closed or liquidated when their maintenance margin is too low.
Here, a trader’s profit and loss does not reflect the actual price their position was closed on the market, and with BitMEX when a trader is liquidated, their equity associated with the position drops down to zero.
In the following example, the trader has taken a 100x long position. In the event that the mark price of Bitcoin falls to $3,980 (by 0.5%), then the position gets liquidated with the 100 Bitcoin position needing to be sold on the market.
This means that it does not matter what price this trade executes at, namely if it’s $3,995 or $3,000, as from the view of the liquidated trader, regardless of the price, they lose all the equity they had in their position, and lose the entire one Bitcoin.
https://preview.redd.it/wel3rka04cc41.png?width=669&format=png&auto=webp&s=3f93dac2d3b40aa842d281384113d2e26f25947e
Assuming there is a fully liquid market, the bid/ask spread should be tighter than the maintenance margin. Here, liquidations manifest as contributions to the insurance fund (e.g. if the maintenance margin is 50bps, but the market is 1bp wide), and the insurance fund should rise by close to the same amount as the maintenance margin when a position is liquidated. In this scenario, as long as healthy liquid markets persist, the insurance fund should continue its steady growth.
The following graphs further illustrate the example, and in the first chart, market conditions are healthy with a narrow bid/ask spread (just $2) at the time of liquidation. Here, the closing trade occurs at a higher price than the bankruptcy price (the price where the margin balance is zero) and the insurance fund benefits.
Illustrative example of an insurance contribution – Long 100x with 1 BTC collateral
https://preview.redd.it/is89ep924cc41.png?width=699&format=png&auto=webp&s=f0419c68fe88703e594c121b5b742c963c7e2229
(Note: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,978, representing $1 of slippage compared to the $3,979 bid price at the time of liquidation.)
The second chart shows a wide bid/ask spread at the time of liquidation, here, the closing trade takes place at a lower price than the bankruptcy price, and the insurance fund is used to make sure that winning traders receive their expected profits.
This works to stabilize the potential for returns as there is no guarantee that healthy market conditions can continue, especially during periods of heightened price volatility. During these periods, it’s actually possible that the insurance fund can be used up than it is built up.
Illustrative example of an insurance depletion – Long 100x with 1 BTC collateral
https://preview.redd.it/vb4mj3n54cc41.png?width=707&format=png&auto=webp&s=0c63b7c99ae1c114d8e3b947fb490e9144dfe61b
(Notes: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,800, representing $20 of slippage compared to the $3,820 bid price at the time of liquidation.)
The exchange declared in February 2019, that the BitMEX insurance fund retained close to 21,000 Bitcoin (around $70 million based on Bitcoin spot prices at the time).
This figure represents just 0.007% of BitMEX’s notional annual trading volume, which has been quoted as being approximately $1 trillion. This is higher than the insurance funds as a proportion of trading volume of the CME, and therefore, winning traders on BitMEX are exposed to much larger risks than CME traders as:
  • BitMEX does not have clearing members with large balance sheets and traders are directly exposed to each other.
  • BitMEX does not demand payments from traders with negative account balances.
  • The underlying instruments on BitMEX are more volatile than the more traditional instruments available on CME.
Therefore, with the insurance fund remaining capitalized, the system effectively with participants who get liquidated paying for liquidations, or a losers pay for losers mechanism.
This system may appear controversial as first, though some may argue that there is a degree of uniformity to it. It’s also worth noting that the exchange also makes use of Auto Deleveraging which means that on occasion, leveraged positions in profit can still be reduced during certain time periods if a liquidated order cannot be executed in the market.
More adventurous traders should note that while the insurance fund holds 21,000 Bitcoin, worth approximately 0.1% of the total Bitcoin supply, BitMEX still doesn’t offer the same level of guarantees to winning traders that are provided by more traditional leveraged trading platforms.
Given the inherent volatility of the cryptocurrency market, there remains some possibility that the fund gets drained down to zero despite its current size. This may result in more successful traders lacking confidence in the platform and choosing to limit their exposure in the event of BitMEX being unable to compensate winning traders.

How suitable is BitMEX for Beginners?

BitMEX generates high Bitcoin trading levels, and also attracts good levels of volume across other crypto-to-crypto transfers. This helps to maintain a buzz around the exchange, and BitMEX also employs relatively low trading fees, and is available round the world (except to US inhabitants).
This helps to attract the attention of people new to the process of trading on leverage and when getting started on the platform there are 5 main navigation Tabs to get used to:
  • **Trade:**The trading dashboard of BitMEX. This tab allows you to select your preferred trading instrument, and choose leverage, as well as place and cancel orders. You can also see your position information and view key information in the contract details.
  • **Account:**Here, all your account information is displayed including available Bitcoin margin balances, deposits and withdrawals, and trade history.
  • **Contracts:**This tab covers further instrument information including funding history, contract sizes; leverage offered expiry, underlying reference Price Index data, and other key features.
  • **References:**This resource centre allows you to learn about futures, perpetual contracts, position marking, and liquidation.
  • **API:**From here you can set up an API connection with BitMEX, and utilize the REST API and WebSocket API.
BitMEX also employs 24/7 customer support and the team can also be contacted on their Twitter and Reddit accounts.
In addition, BitMEX provides a variety of educational resources including an FAQ section, Futures guides, Perpetual Contracts guides, and further resources in the “References” account tab.
For users looking for more in depth analysis, the BitMEX blog produces high level descriptions of a number of subjects and has garnered a good reputation among the cryptocurrency community.
Most importantly, the exchange also maintains a testnet platform, built on top of testnet Bitcoin, which allows anyone to try out programs and strategies before moving on to the live exchange.
This is crucial as despite the wealth of resources available, BitMEX is not really suitable for beginners, and margin trading, futures contracts and swaps are best left to experienced, professional or institutional traders.
Margin trading and choosing to engage in leveraged activity are risky processes and even more advanced traders can describe the process as a high risk and high reward “game”. New entrants to the sector should spend a considerable amount of time learning about margin trading and testing out strategies before considering whether to open a live account.

Is BitMEX Safe?

BitMEX is widely considered to have strong levels of security. The platform uses multi-signature deposits and withdrawal schemes which can only be used by BitMEX partners. BitMEX also utilises Amazon Web Services to protect the servers with text messages and two-factor authentication, as well as hardware tokens.
BitMEX also has a system for risk checks, which requires that the sum of all account holdings on the website must be zero. If it’s not, all trading is immediately halted. As noted previously, withdrawals are all individually hand-checked by employees, and private keys are never stored in the cloud. Deposit addresses are externally verified to make sure that they contain matching keys. If they do not, there is an immediate system shutdown.
https://preview.redd.it/t04qs3484cc41.jpg?width=808&format=pjpg&auto=webp&s=a3b106cbc9116713dcdd5e908c00b555fd704ee6
In addition, the BitMEX trading platform is written in kdb+, a database and toolset popular amongst major banks in high frequency trading applications. The BitMEX engine appears to be faster and more reliable than some of its competitors, such as Poloniex and Bittrex.
They have email notifications, and PGP encryption is used for all communication.
The exchange hasn’t been hacked in the past.

How Secure is the platform?

As previously mentioned, BitMEX is considered to be a safe exchange and incorporates a number of security protocols that are becoming standard among the sector’s leading exchanges. In addition to making use of Amazon Web Services’ cloud security, all the exchange’s systems can only be accessed after passing through multiple forms of authentication, and individual systems are only able to communicate with each other across approved and monitored channels.
Communication is also further secured as the exchange provides optional PGP encryption for all automated emails, and users can insert their PGP public key into the form inside their accounts.
Once set up, BitMEX will encrypt and sign all the automated emails sent by you or to your account by the [[email protected]](mailto:[email protected]) email address. Users can also initiate secure conversations with the support team by using the email address and public key on the Technical Contact, and the team have made their automated system’s PGP key available for verification in their Security Section.
The platform’s trading engine is written in kdb+, a database and toolset used by leading financial institutions in high-frequency trading applications, and the speed and reliability of the engine is also used to perform a full risk check after every order placement, trade, settlement, deposit, and withdrawal.
All accounts in the system must consistently sum to zero, and if this does not happen then trading on the platform is immediately halted for all users.
With regards to wallet security, BitMEX makes use of a multisignature deposit and withdrawal scheme, and all exchange addresses are multisignature by default with all storage being kept offline. Private keys are not stored on any cloud servers and deep cold storage is used for the majority of funds.
Furthermore, all deposit addresses sent by the BitMEX system are verified by an external service that works to ensure that they contain the keys controlled by the founders, and in the event that the public keys differ, the system is immediately shut down and trading halted. The exchange’s security practices also see that every withdrawal is audited by hand by a minimum of two employees before being sent out.

BitMEX Customer Support

The trading platform has a 24/7 support on multiple channels, including email, ticket systems and social media. The typical response time from the customer support team is about one hour, and feedback on the customer support generally suggest that the customer service responses are helpful and are not restricted to automated responses.
https://preview.redd.it/8k81zl0a4cc41.jpg?width=808&format=pjpg&auto=webp&s=e30e5b7ca93d2931f49e2dc84025f2fda386eab1
The BitMEX also offers a knowledge base and FAQs which, although they are not necessarily always helpful, may assist and direct users towards the necessary channels to obtain assistance.
BitMEX also offers trading guides which can be accessed here

Conclusion

There would appear to be few complaints online about BitMEX, with most issues relating to technical matters or about the complexities of using the website. Older complaints also appeared to include issues relating to low liquidity, but this no longer appears to be an issue.
BitMEX is clearly not a platform that is not intended for the amateur investor. The interface is complex and therefore it can be very difficult for users to get used to the platform and to even navigate the website.
However, the platform does provide a wide range of tools and once users have experience of the platform they will appreciate the wide range of information that the platform provides.

IOTA Definition

IOTA Definition
History of IOTA
The blockchain was announced in October 2015 through. The roots of IOTA go back to the Jinn project. That project aimed to develop ternary hardware or low-cost and energy-efficient hardware, primarily general-purpose processors, for use in the IoT ecosystem. Jinn held a crowd sale for its tokens in September 2014. The Jinn tokens were soon in hot water because they marketed as profit-sharing tokens.. In 2015, Jinn was rebranded as IOTA, and another token sale was held. This time around, the tokens were marketed as utility tokens, and Jinn token holders could exchange their tokens at equivalency with the new blockchain. According to David Sønstebø, IOTA was “spawned” due to the Jinn project. But reports state that a snapshot of the genesis transaction is yet to be found online. These tokens were dispersed to other “founder” addresses. The total number of mIOTAs planned to be in existence is 27 quadrillion. According to IOTA’s founders, the total number of mIOTAs fits in “nicely” with the maximum allowable integer value in Javascript, a programming language.
Understanding IOTA
According to research firm Gartner, there will be 20.4 billion devices connected to the Internet by 2020. Within this ecosystem, each device will exchange data and payment information with multiple, other devices in transactions conducted throughout the day. IOTA intends to become the standard mode of conducting transactions on devices. Its founders have described the ledger as a “public permission-less backbone for the Internet of Things that enables interoperability between multiple devices.” In simple words, this means that it will enable transactions between connected devices, and anyone will be able to access it. Those problems are primarily caused due to a backlog of transactions on Bitcoin’s blockchain. The backlog itself is because of a variety of reasons, from small block sizes to the difficulty of puzzles that miners must solve to earn the cryptocurrency as a reward. IOTA solves these problems by reconfiguring blockchain's architecture into Tangle, a new way of organizing data and confirming transactions.
How Does IOTA Solve Bitcoin’s Scalability Problems?
IOTA’s solution to Bitcoin’s problems is to do away with several key concepts and topographical constraints of a blockchain. mIOTA, IOTA’s cryptocurrency, is pre-mined and consensus of transactions occurs differently as compared to a blockchain. IOTA developers have proposed a new data structure. Tangle is a Decentralized Acyclic Graph, a system of nodes which is not sequential. Thus, each node can be connected to multiple other nodes in a Tangle. But they are connected only in a particular direction, meaning that a node cannot refer back to itself. A standard blockchain is also a DAG because it is a sequential linked set. In Bitcoin, a group of systems running full nodes that contain the entire history of transactions for a ledger are required for confirmations and consensus. Full node miners are not required in Tangle. Each new transaction is confirmed by referencing two previous transactions, reducing the amount of time and memory required to confirm a transaction. Related to the concept of a “confidence” is a transaction’s weight. As it moves through Tangle, a transaction gathers weight. A transaction’s weight increases with the number of approvals. Once a transaction is confirmed, it is broadcast to the entire network, and another unconfirmed transaction can choose the newly-confirmed transaction as one of the tips to confirm itself.
Governance Protocol
IOTA has not outlined a governance structure for its blockchain. The IOTA Foundation is primarily responsible for funding and leading development of IOTA. In a previous post, John Licciardello, former managing director of IOTA's Ecosystem Development Fund (EDF), that would allow members of the IOTA community to vote on proposals regarding its future direction. But there are no updates on the initiative yet.
Concerns About IOTA
Criticism of IOTA has mainly centered around its technical flaws. As with most cryptocurrencies, IOTA’s system is nascent and unproven. A phishing attack on its network resulted in the theft of mIOTA worth $3.94 million. In other words, they created their encryption scheme from scratch, forgoing the widely-used SHA-256 hash function used in Bitcoin. The team at MIT’s Digital Currency Initiative found serious vulnerabilities with IOTA’s hash function, which is called Curl. This property is known as Collision and denotes a broken hash function. In their analysis of the vulnerability, the MIT team stated that a bad actor could have destroyed or stolen user funds from Tangle with their technique. IOTA’s team has corrected the vulnerability. The foundation announced a new partnership with Ledger, one of the leading producers of hardware wallets. IOTA technology will be integrated into the hardware wallets, giving users the ability to store the private key information in a device that adds another layer of protection from hackers.
https://preview.redd.it/ex768bb74gw31.jpg?width=777&format=pjpg&auto=webp&s=4e89f0875410274a85b76227c17d321b5c3d29ed
“The collaboration between the teams created an immediate synergy concentrated on developing a compatibility feature allowing users to access, store and manage IOTA tokens on Ledger devices. 

The IOTA (MIOTA) digital asset suffered from a lack of adequate wallets for months, even at the peak of the market. The asset, which commanded prices above $5, was not spared by the bear market. Despite the launch of the long-awaited Trinity wallet, MIOTA lost positions. Given that mIOTA, the crypto used in IOTA, is still to gain mainstream traction, its claims to eliminate scalability problems for blockchains through the use of DAGs are also still to be proven. Vitalik Buterin, the co-founder of Ethereum, has cast doubt on the ability of hashgraphs to solve scalability issues.
Another problem with IOTA currently is the small size of its network. Researchers have found that hackers need only gain control of 33% of the total hashing power required to bring it down. In Bitcoin, control of 51% of a network is required to bring its blockchain down. To ensure security, IOTA’s network currently uses a central server known as a Coordinator to process transactions. This practice has diluted its claims of being a decentralized system since the introduction of a Coordinator has resulted in the introduction of a single point of failure.
The consensus system is described in a new white paper. In the past, IOTA has been criticized for its hidden centralization, as well as for the loss of coins sometimes happening when a user’s wallet was unable to receive its previous balances from the state of the Tangle.
But despite the innovation, IOTA lags behind digital assets that are receiving the most significant inflows of investment and trading liquidity.

#6 lessons for newcomers: My 1 year XRP journey. Fundamentals, FOMO, FUD & Greed on the path to $5 and beyond.

6 crucial things I learned in 2017.

 
As I find it difficult to share this story with friends and family so I turn to this community. They either don’t understand or think everything that sounds like crypto is a bubble.
 
Also I hope that this story might help others to avoid the mistakes I made.
 
TLDR: * I fundamentally believe in XRP and ~10x’ed my FIAT so far (compared to $), * Could have 15x’ed if I would have not have made emotional decisions based on greed, fomo and FUD, * Make rules for yourself and stick to them. Period, * I will buy XRP till $5, * Bitstamp is a great exchange but at some point definitely secure your holdings with some level of paranoia.
 
This story is about my personal journey on the XRP train. A story about fundamental analysis, FOMO (fear of missing out), FUD (fear uncertainty and doubt), my greed, emotional trading, belief in XRP and patience.
 
My journey started with bitcoin actually in ~ 2013. I had this friend who kept talking about this bitcoin that will change the world.
 
It was around $600 at the time, I told him he was crazy and it was a bubble, without even researching it I waved his words away.
 
The higher BTC rose, the more effort I made to tell him it was a bubble and it would crash.
 
At some point it did, after reaching ~1200 or so. Major crash.
I was right!
 
In ~ 2014 I had to buy a few BTC to perform a transaction on a infamous dark web market place that is no longer.
 
After that, I forgot about bitcoin and crypto currencies….
 
Fast forward to January 2017. Crypto is on my radar again, it’s still there…
 
I start reading and following the rapid growth of BTC until April 2017. I don’t understand BTC craze. Of course, it was the first, the tech is revolutionary but there are some problems for me;
 
 
Also I found out about this ‘other thing’, XRP.
 
The more I read the more I believe in the fundamentals;
 
I soon figure out this crucial part:
If banks adopt Ripple’s software and later XRP as a bridge for international transfers they will likely need to purchase XRP to execute these transfers
 
If banks for example need to send $10 Billion, there needs to be sufficient liquidity in the XRP market for such a large USD amount to flow through XRP.
 
In May 2017, XRP is 0.22 USD with a market cap of ~ 9 Billion USD.
How the hell will banks be able to send large amounts of FIAT through XRP without causing massive price swings?
 
They cannot. I figured that if banks were going to use XRP to send let’s say USD 1 trillion on a daily basis XRPs unit price would need to be WAAAYY higher.
 
Let’s Imagine 75% of the coins is being held and not actively trading. 25% of the total supply is being traded on a daily basis. For 1 trillion USD to pass through that 25% should be at least valued at 1 Trillion USD. But likely higher because everyone involved in this want a stable price.
 
I thought that if Ripple succeeds and banks adopt Ripple’s software, it is likely that Ripple will convince banks to use XRP as well.
 
Betting on Ripple the company I believed that XRP was massively undervalued at .22 USD, especially in comparison with coins such as BTC, LTC and some others.
 
After reading up on Ripple and XRP for 2 months straight I decided to buy in for 20% of my net worth (yes, huge gamble and not recommended).
 
I buy Bitcoin at a local broker with a ~4% spread and send the BTC to Bitstamp. Upon arrival on Bitstamp a few hours later I realise that some of my BTC is missing. High transaction fees and a relatively big spread between the broker’s price and the price on bitstamp I find out later.
 
I told myself to hold XRP for 5 years.
 
This is how my journey goes after that:
 
At this point I am still high in profits (could be more if I did not sell though..)
 
 
As of now I feel very happy with 10x gains on the total FIAT amount I put in. However I also feel stupid for not sticking to my plan of holding XRP for 5 years without trading. If I had stuck to my plan I would have been up 15x by now.
 
My new plan:
 
I learned some things:
 
Hopefully this story might be of some use.
 
To all /Ripple'ers, big thanks; especially to those answering questions from newcomers and to those keeping thus sub high quality and free of memes and other low quality posts.
 
Wishing everyone a great start of 2018 and happy holding!

OK! Hold you thoughts! Will this shit gonna get real?? I mean PI Crypto!

Honestly, i was one of the disappointed late arrivals who like everyone else witnessed the blow up of bitcoin and its scarcity to everyday guy like me.
Will PI gonna be my redemption and my second chance??
Am i fool of it?
Well all that in mind and Check out a little explanation to see if PI is worth a try?
Pi is a new digital currency being developed by a group of Stanford PhDs. For a limited time, you can join the beta to earn Pi and help grow the network.
To join Pi this insanely beautiful revolutionary idea and have your slice of the PI, Download the app using this link and use my username (IscoFe) as your invitation code.
Is this crypto mining app that is beginning to spread virally all it is cracked up to be? I was introduced to it by my wife who received an invitation from a close friend of ours. I actually heard about it first via a friend of mine named Charles Fuchs on Steemit but since I am bombarded by new projects on a daily basis I never took the time to dive any further into the Pi Network information.

What Is The Pi Network?

The Pi Network is a cryptocurrency that uses Proof of Work without the need to burn massive amounts of electricity. You can mine on your phone without using up battery power. It is decentralized, mobile-based and eco-friendly.
Our Mission: Build a cryptocurrency and smart contracts platform secured and operated by everyday people.
Our Vision: Build the world’s most inclusive peer-to-peer marketplace, fueled by Pi, the world’s most widely used cryptocurrency

The Pi Network Has Three Phases.

Phase 1- Design, Distribution, Trust Graph Bootstrap.
During this phase, the team will distribute tokens on a centralized Pi server. The team will be testing and improving aspects of the Pi Network and app. The Pi coin will not be listed on any exchanges during this period.
Phase 2- Testnet.
During this phase, the team will begin deploying Pi Network nodes as well as allow users to run their own nodes on the Testnet. This will be used to test the Nodes against the phase 1 emulator.
Phase 3- Mainnet.
It is time for Primetime! The emulator will be shut down and the network will be allowed to operate on its own. Similar to other cryptocurrency projects Pi Network will be open to developers to join the community and improve the network alongside the original team. During this phase, the Pi Network coin will be listed on exchanges.

If You Want To Dive Into The Token Economics. Go For It!
Pi’s economic model design requirements:

Pi - Token Supply

Token Emission Policy

  1. Total Max Supply = M + R + D
    1. M = total mining rewards
    2. R = total referral rewards
    3. D = total developer rewards
  2. M = ∫ f(P) dx where f is a logarithmically declining function
    1. P = Population number (e.g., 1st person to join, 2nd person to join, etc.)
  3. R = r * M
    1. r = referral rate (50% total or 25% for both referrer and referee)
  4. D = t * (M + R)
  5. t = developer reward rate (25%)

But Did you ask me Hey Sisco, Pi Network Is Mined On Your Phone And People Refer Each Other.

I know, it is off-putting for old school cryptocurrency folks like myself. I love my Proof of Work coins and Privacy coins. But I refuse to miss out on something different just because I might not agree with these aspects of the project.
I am going to tell you a little story about my cryptocurrency early years. I was really reluctant to buy Bitcoin prior to 2014 even though I knew all about it in 2011. The reason was I was a Gold and Silver guy and the idea of digital money was something I struggled with. It really took Bitcoin going stratospheric in 2013 to really get my attention. So I missed out on a great opportunity.
I vowed that I would not let it happen again. Now I see the opportunity to put cryptocurrency into the hands of people around the world using their phones. MINDBLOWN!

I would take a moment to remind people of normal seasonal behavior.

There's clearly alot of drama going on in all of crypto, but let's not forget about large underlying reasons of price and market-movements.
If we look at the global market price graphs over last 24 hours https://coinmarketcap.com/
We can see that this is not just about bitcoin vs other alts, this is just normal human seasonal behavior. This happened 2014, 2015, 2016 and now 2017 where alot of people invest and where interest and trading volumes are high and spiking around oct-nov and then in dec people celebrate christmas/new years and the general public wont have the same buying influence that normally (over the year) keep the flow of buyers vs sellers in a healthy state.
This lower overall stream of buy-pressure from mainstream adaptors usually is lower across all crypto over this season and normalizes again around february.
My point is probably more to remind myself and all that care about some of the large underlying influences on movement of markets come from normal human seasonal behavior and that we should not forget about these overarching trends in finance and crypto when discussing price over mid-long terms.

Stability Confirmation

Low comments...
Quiet sub...
Weekly BBands still tightening...
Time to review the stability projections from June. This week marks 7 weeks since the stability projection was established. 7 weeks is the minimum period of time I had established to identify a historically stable period. This chart shows that we've managed to hold the price within a range that's consistent with past periods of stability.
https://www.tradingview.com/x/gZ3lgMZf/
We've also decisively broken out from the 2014 crash pattern.
Fuschia and lime projections look like the best match. Those projections also make it look like we're on track for a shorter period of stability... but both of those patterns maintained stability for 9 and 11 weeks, which appears to be a moderately long period of stability. If the pattern holds then we should see weekly bbands continue to contract.
Green and black projections are also compelling.

Log Projections

https://www.moonmath.win
The Moon Math site added two new projections to the homepage and improved the way the range is set on graphs so you can see the whole projection for all the bands. Projections extend out to 2021 now, too. Really, it's one projection with one chart zoomed in substantially closer. THey're presented as a sort of alternative view of azop 's original rainbow charts... which are still tracking at ~ 0.3 % CDPR daily.
A while ago I published a tradingview script that recreates the center yellow line here:
https://www.tradingview.com/script/GoAfLP25-Log-Projection-Orig/
I threw out some additional scripts that are related to this chart, too:
I haven't been able to figure out how to make projections like this using pinescript on TV. If anyone has a technique, I'd love to get my hands on that.
The log calculation originated here in 2014
You can check today's value for the yellow line by going here
The width of the bands on the log chart is determined using the same method that the exponential chart uses. It looks a little wonky, but I didn't want to spend time working out a more accurate calculation only to land on a nearly identical chart.
Good hunting.

All About Zcoin

All About Zcoin

https://preview.redd.it/hixbz9f3lxm31.jpg?width=1200&format=pjpg&auto=webp&s=43896de84a3693d840c84057c0314af71718f0a3
What is Zcoin?
Zcoin, also referred to as XZC or Zerocoin, is an open source decentralized cryptocurrency that provides privacy and anonymity for its users when making transactions.
To achieve its privacy and anonymity, Zcoin uses zero-knowledge proofs via the Zerocoin protocol, which is at this moment in time one of the most cited cryptography papers.
According to Wikipedia, in cryptography, a zero-knowledge proof or zero-knowledge protocol is a method in which one party proves to another party (the verifier) that a given statement is actually true.
In other words, in a transaction with Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default, leaving you vulnerable. All it takes is one link to your personal information or IP to find out the origin of the coins.
However, when you trade with Zcoin’s Zercoin feature, your transaction history is not linked to the actual coins. Only the receiver and sender know that the funds have actually been exchanged.

How Does Zcoin Work?

Zcoin works on the Zerocoin protocol by enforcing Zero-knowledge proofs. Here are the components of Zcoin to explain how it works.
Mint: When sending a private transaction with Zcoin, all you need to do is select the number of coins you want to mint. Post that your normal Zcoin balance would reduce automatically and you will be credited with new coins and no transaction history. In essence, your old coins are burned cryptographically, which prevents anyone else from using them again and being directed to your transaction history. You get credited with new coins with no history, while the total supply is maintained.
For now, you can only mint in denominations of 1, 10, 25, 50 and 100. If you choose ‘100’ coins to be minted, for instance, you will instantly be credited with 100 new Zcoins with no history attached to them.
  • Spend: When you want to make a private transaction, you will be required to use these ‘100’ newly minted coins. From this pool of funds, you can now send any amount in any denomination to anyone anonymously because no history is attached to it.
  • Repeat: You can ‘mint’ and ‘send’ Zcoins any number of times at anytime with your privacy intact.

Zcoin’s Vision

Zcoin seeks to improve things that Bitcoin hasn’t been able to so far, some of which include fungibility, privacy and miner’s centralization.
Users of Zcoin can enjoy full fungibility and privacy along with demolishing miner’s centralization by implementing a better proof of work algorithm called MTP.
Total Zcoin supply
Only 21 million units of Zcoin will ever be produced. Currently, there are about 3.4 million units in circulation, with the rest yet to be mined.
But the total supply has increased by 388450 XZC units after a Zcoin code bug, which the team refused to roll back due to economic reasons, which is why the total supply stands at approximately 21.4 million.
Every 10 minutes, a Zcoin block is mined and 50 coins are generated, making 72,000 Zcoins per day.
Market cap of Zcoin
According to CoinMarketCap, the total circulating supply of Zcoin is 5,757,841 XZC and the current unit price is $9.6. That makes the market cap approximately $55 million*.*

Zcash:
Zcash is a decentralized and open-source peer-to-peer cryptocurrency that provides strong privacy protections. It was created as a fork of Bitcoin and, like bitcoin, it also has a hard limit of 21 million coins. Unlike bitcoin, however, Zcash offers total privacy for its users maintaining the absolute anonymity behind each transaction along with the parties and the amounts involved in it.
PIVX:
PIVX, which stands for Private Instant Verified Transaction, is an open-source, decentralized form of digital online money that uses blockchain technology. This makes it easy to transfer all around the world in an instant with low transaction fees with market leading security & privacy. PIVX focuses on privacy, security, anonymity, and instant transactions.
Monero:
Monero is a fast, private, secure and untraceable digital currency system that uses a special kind of cryptography to keep all its transactions 100% unlinkable and untraceable. With Monero, you are your own bank. You can spend safely, knowing that others cannot see your balances or track your activity.
Some Zcoin misconceptions
There are some misconceptions regarding Zcoin:
  • Some believe that, since Zcoin has a trusted setup that allows indefinite minting of coins, it is not safe. This is untrue. Of course, to start with they had to use a trusted setup because they have an auditable total coin supply that prevents any form of cheating. This downside however, is being taken care of by removing this trusted setup in the near future and when that happens, Zcoin will be one of the serious coins to count on for privacy.
  • Zcoin has been considered as Zcash’s fork but that is also not true because Zcash is based on the Zerocash protocol whereas Zcoin was started from scratch by applying Zerocoin tech.
Now that some of the Zcoin’s misconceptions have been cleared, here’s a look into its future.

Zcoin’s Future & Roadmap

Zcoin’s future is quite promising and worth watching based on these interesting milestones on their roadmap:
  • Zcoin is the first coin to implement MTP proof of work, which makes it possible for general masses to mine Zcoin with GPUs and CPUs. MTP doesn’t allow costly ASIC-like miners to mine XZC coins.
  • Zcoin is also implementing Znodes to make their cryptocurrency more decentralized and anonymous. These Znodes will be like masternodes and facilitate anonymous transactions as making an anonymous transaction single-handedly is quite computational.
  • Znodes will be incentivized by reducing some portion of the founder’s reward. Also, the surplus funds that get generated from the founder’s reward reduction would be used for hiring new developers and increased marketing efforts.
  • Another agenda on their roadmap is to bring inbuilt Tor or some IP obfuscation mechanism that will make it completely anonymous.
  • Apart from these, some innovative and exciting things like sigma protocol, decentralized anonymous voting and Zcoin Labs are on their roadmap, making this project worth checking out.
  • Last but not least, its recent price is a good indicator of its healthy market sentiment and shows that there are people who understand this project’s worth. Just to put things into perspective – a unit of Zcoin was priced $2 in March 2017 and now it is $37*.*

Zcoin Team & Progress

Zerocoin is a cryptocurrency proposed by professor Matthew D. Green, a professor of Johns Hopkins University, and graduate students Ian Miers and Christina Garman. It was proposed as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions.
Zerocoin was first implemented into a fully functional cryptocurrency and released to the public by Poramin Insom, the lead developer, as Zcoin in September 2016.
Some of the notable dev members of the team are listed below.
Poramin Insom
Founder and Core Developer
Poramin Insom created what was the world's 4th most valuable cryptocurrency in February 2014. He is also the world's first person to implement stealth addresses in QT-Wallets, improving cryptocurrency anonymity. He earned a master’s degree in Information Security from Johns Hopkins University, where he wrote a paper on a proposed practical implementation of the Zerocoin protocol.
Alexander N.
Developer
Alexander N. aka Aizensou is a full-stack developer who has experience in many programming languages (C++, C#, Python, Perl, Java etc.) and has been involved in the cryptocurrency space since 2013. He has a broad development portfolio from low level APIs in Python and C++ to Android native applications in Java. In addition to his involvement in cryptocurrencies, Alexander was doing his P.h.D. in machine learning at a German university from 2012 to 2016.
Saran Siriphantnon
Developer
Saran Siriphantnon is the CTO of Satang.co/Satoshift, a fintech company focusing on creating an open financial system for Southeast Asia. He served as President of the Computer System Administrator Group at King Mongkut's Institute of Technology Ladkrabang.
Tadhg Riordan
Solidity Developer
Tadhg Riordan is a 24 year old Software Developer from Wexford, Ireland. He recently completed his MSc from Trinity College Dublin, where he worked with Blockchain privacy mechanisms, focusing particularly on Zero-Knowledge Proofs and the Ethereum platform. He is a strong advocate for the adoption of cryptocurrency and for complete financial privacy.
Apart from these, their team comprises of other developers, community managers, support personnel and advisors who maintain the required balance.

Advisors:

Aram Jivanyan (Cryptography Advisor): Co-Founder at Skycryptor & KMSchai
Torphop Korgtadam (It Security Consultant): Senior Vice President, Head Of Internal Audit Strategy, Innovation and Decision Science at United Overseas Bank Limited
Alexander N. aka Aizensou (Advisor)

Unique/Key Features Against Its Competitors:

  • Anonymous transactions. The project establishes a notably higher level of anonymity and seeks to bypass current analysis techniques which governments use to reveal the identity of users.
  • Not subject to transaction graph analysis. Zcoin has an anonymity set that encompasses all minted coins in a particular RSA accumulator that can scale to many thousands.
  • Innovative process. Tokens are burned cryptographically and replaced with new coins without a transaction history. This actively prevents anyone else from using the tokens again and stops the public from being directed to a user's transaction history.
  • Transparency focused. Zcoin's main advantage is its auditable money supply.

A Guide To Buying and Selling Premium Bitcoin

Introduction
All Bitcoin are created equal, but they rarely remain that way.
With the traceability and open nature of Bitcoin's Blockchain, individual Bitcoin and satoshis can be traced back to cypherpunk giants like Hal Finney, or even Satoshi Nakamoto himself. Furthermore, newly minted, or old-minted-but-never-moved Bitcoin trade at a significant premium, compared to the Bitcoin spot price (it's been reported that there have been premiums of 15-20% for coinbase Bitcoin).
These coins are novelties. Collectables. Because they can be tracked, identified and are cryptographically verifiable.
So with that dynamic in place, there is an opportunity for a Premium Bitcoin market to form. This subreddit will attempt to form the infancy of that market for retail customers, and perhaps whales.
Instructions for Buyers on making a Post
If you wish to buy a specific kind of coin you can make a post is this subreddit starting with
  1. "[WTB]"
  2. followed by the kind of Bitcoin you wish to buy,
  3. followed by specific requirements, like the number of transactions away from the source/event/coinbase/person/exchange
  4. followed by the premium above spot price as a percentage in which you are willing to buy the novelty, collectable or even tainted Bitcoins.
  5. followed by your preferred payment method
Examples:
[WTB] 1 Satoshi Nakamoto Bitcoin, 1 transaction away from coinbase: 100% above spot - USDC
[WTB] 2 Bitcoin Coinbase from 2013, less then 2 transactions away from origin: 21% above spot - Bitcoin
[WTB] 0.5 Silk Road Bitcoin, any length of transactions away from origin: -10% below spot - Monero
Instructions for Sellers on making a Post
If you believe you have collectable, unique or novelty Bitcoin for sale, you can make a post in this subreddit starting with
  1. [WTS]
  2. followed by the kind of Bitcoin you wish to sell,
  3. followed by any specifics of those Bitcoin, like the number of transactions away from the event/source/coinbase/person/exchange
  4. followed by the asking premium above spot price as a percentage you wish to charge for the novelty, collectable or even tainted Bitcoins.
  5. followed by what kind of payment you accept
Examples:
[WTS] 1 Satoshi Nakamoto Bitcoin, 2 transactions away from coinbase, 121% above spot - Accepting Bitcoin, ETH, USDC
[WTS] 25 Bitcoin coinbase, from 2014 has not be moved, asking for 25% above spot - Accepting USDT
[WTS] 1 Hacked Bitfinex Bitcoin, 21 transactions away from source, -20% below spot - Accepting Monero
Instructions for Escrow Agents on making a Post
If you want to offer your escrow services to facilitate the buying and selling of Premium Bitcoin between two parties then you can make a post in this subreddit starting with
  1. [EA]
  2. a short description of yourself
  3. the percentage or flat rate you will charge for your services
  4. any extra features available
  5. payment methods accepted
Examples:
[EA] Experienced and Reviewed Escrow Agent here to help, flat rate of 0.01BTC - all payment methods accepted
[EA] Bitrated verfied Escrow Agent, 0.5% commission - physical opendime optional for 150$ more - Bitcoin and USDC accepted upfront
Best Practices for Buyers, Sellers and Escrow Agents
once you submit a post, a seller may try to contact you by private message, chat, or by replying to your post. Most will claim that they have what you are looking for. But you will need to verify on your own that the person you are communicating with does have the type of coins you are looking for. You can verify this by having the seller who contacts you sign a message from the address that holds the coins that satisfy your buying requirements.
It's recommended that the verification message format be something like "I am ."
Further instructions on signing messages can be found here:
http://support.vaultoro.com/knowledgebase/articles/536758-how-do-i-sign-a-message-with-my-bitcoin-wallet
https://www.youtube.com/watch?v=B4GZ4qDEanA
https://www.youtube.com/watch?v=S88ciN9DsRk
Once the buyer has verified the coins are possessed by the seller with a signed message from the seller, the transaction can begin. Other useful tools for looking up the transaction trail of the coins being sold can be found here:
blockpath.com
blockchain3d.info
symphony.iohk.io
walletexplorer.com
a list of MTGox cold wallet coins
a list of historic bitcoin transactions
It's recommended that a trusted third party escrow agent be used to ensure that neither party scams another. It's important that the seller, buyer and escrow agent all know the details of the transaction that is to occur, including the evidence to support the Bitcoins novelty. It's important that the buyer conduct his due diligence in verifying the evidence of the coins authenticity and related history. If possible, the escrow agent should do the same.
To find a escrow agent, a buyeseller can search this subreddit for EA posts, use www.bitrated.com to search for a trusted escrow, or use a different escrow agent service that they both agree to using.
Once all parties are clear on the details of the transactions, including the EA's fee, the transaction can proceed. If the transaction is successful, please let us know in the original subreddit posting.

The number of addresses with a balance of more than 1000 BTC is growing at a pace up to 2014

The number of addresses with a balance of more than 1000 BTC is growing at a pace up to 2014

https://preview.redd.it/bxnlgpmstms31.jpg?width=900&format=pjpg&auto=webp&s=e8d31576865463368dc37107e10adf4dc8fd0f9d
In the Bitcoin blockchain, the concentration of capital is growing: the number of addresses containing more than 1000 BTC ($8.3 million at the current exchange rate), in 2019, increases at the same pace as in 2010-2013.
A graph of the growth of the balance of bitcoin addresses, published by analyst Willy Woo shows that the network is now repeating the trend of the earliest years.
According to Woo, the new round of growth in the balance sheet of companies at significantly higher prices than five years ago, suggests that the industry is coming more wealthy investors. If those who had more than 1000 BTC before 2014, mainly purchased the cryptocurrency out of technical interest, then the incentives in 2019 are purely financial. Woo concluded:
"As it seems to me, bitcoin is experiencing another Renaissance, the engine of which was the influx of capital from high-yielding investors, while previously the growth of the balance of addresses was associated with tech-savvy users who launched the network."
The data indicate that the current trend of growth in the number of addresses whose balances exceed 1000 BTC, intensified in early 2019.

Bitcoin Original: Reinstate Satoshi's original 32MB max blocksize. If actual blocks grow 54% per year (and price grows 1.54^2 = 2.37x per year - Metcalfe's Law), then in 8 years we'd have 32MB blocks, 100 txns/sec, 1 BTC = 1 million USD - 100% on-chain P2P cash, without SegWit/Lightning or Unlimited

TL;DR
Details
(1) The current observed rates of increase in available network bandwidth (which went up 70% last year) should easily be able to support actual blocksizes increasing at the modest, slightly lower rate of only 54% per year.
Recent data shows that the "provisioned bandwidth" actually available on the Bitcoin network increased 70% in the past year.
If this 70% yearly increase in available bandwidth continues for the next 8 years, then actual blocksizes could easily increase at the slightly lower rate of 54% per year.
This would mean that in 8 years, actual blocksizes would be quite reasonable at about 1.548 = 32MB:
Hacking, Distributed/State of the Bitcoin Network: "In other words, the provisioned bandwidth of a typical full node is now 1.7X of what it was in 2016. The network overall is 70% faster compared to last year."
https://np.reddit.com/btc/comments/5u85im/hacking_distributedstate_of_the_bitcoin_network/
http://hackingdistributed.com/2017/02/15/state-of-the-bitcoin-network/
Reinstating Satoshi's original 32MB "max blocksize" for the next 8 years or so would effectively be similar to the 1MB "max blocksize" which Bitcoin used for the previous 8 years: simply a "ceiling" which doesn't really get in the way, while preventing any "unreasonably" large blocks from being produced.
As we know, for most of the past 8 years, actual blocksizes have always been far below the "max blocksize" of 1MB. This is because miners have always set their own blocksize (below the official "max blocksize") - in order to maximize their profits, while avoiding "orphan" blocks.
This setting of blocksizes on the part of miners would simply continue "as-is" if we reinstated Satoshi's original 32MB "max blocksize" - with actual blocksizes continuing to grow gradually (still far below the 32MB "max blocksize" ceilng), and without introducing any new (risky, untested) "game theory" or economics - avoiding lots of worries and controversies, and bringing the community together around "Bitcoin Original".
So, simply reinstating Satoshi's original 32MB "max blocksize" would have many advantages:
  • It would keep fees low (so users would be happy);
  • It would support much higher prices (so miners would be happy) - as explained in section (2) below;
  • It would avoid the need for any any possibly controversial changes such as:
    • SegWit/Lightning (the hack of making all UTXOs "anyone-can-spend" necessitated by Blockstream's insistence on using a selfish and dangerous "soft fork", the centrally planned and questionable, arbitrary discount of 1-versus-4 for certain transactions); and
    • Bitcon Unlimited (the newly introduced parameters for Excessive Block "EB" / Acceptance Depth "AD").
(2) Bitcoin blocksize growth of 54% per year would correlate (under Metcalfe's Law) to Bitcoin price growth of around 1.542 = 2.37x per year - or 2.378 = 1000x higher price - ie 1 BTC = 1 million USDollars after 8 years.
The observed, empirical data suggests that Bitcoin does indeed obey "Metcalfe's Law" - which states that the value of a network is roughly proportional to the square of the number of transactions.
In other words, Bitcoin price has corresponded to the square of Bitcoin transactions (which is basically the same thing as the blocksize) for most of the past 8 years.
Historical footnote:
Bitcoin price started to dip slightly below Metcalfe's Law since late 2014 - when the privately held, central-banker-funded off-chain scaling company Blockstream was founded by (now) CEO Adam Back u/adam3us and CTO Greg Maxwell - two people who have historically demonstrated an extremely poor understanding of the economics of Bitcoin, leading to a very polarizing effect on the community.
Since that time, Blockstream launched a massive propaganda campaign, funded by $76 million in fiat from central bankers who would go bankrupt if Bitcoin succeeded, and exploiting censorship on r\bitcoin, attacking the on-chain scaling which Satoshi originally planned for Bitcoin.
Legend states that Einstein once said that the tragedy of humanity is that we don't understand exponential growth.
A lot of people might think that it's crazy to claim that 1 bitcoin could actually be worth 1 million dollars in just 8 years.
But a Bitcoin price of 1 million dollars would actually require "only" a 1000x increase in 8 years. Of course, that still might sound crazy to some people.
But let's break it down by year.
What we want to calculate is the "8th root" of 1000 - or 10001/8. That will give us the desired "annual growth rate" that we need, in order for the price to increase by 1000x after a total of 8 years.
If "you do the math" - which you can easily perform with a calculator or with Excel - you'll see that:
  • 54% annual actual blocksize growth for 8 years would give 1.548 = 1.54 * 1.54 * 1.54 * 1.54 * 1.54 * 1.54 * 1.54 * 1.54 = 32MB blocksize after 8 years
  • Metcalfe's Law (where Bitcoin price corresponds to the square of Bitcoin transactions or volume / blocksize) would give 1.542 = 2.37 - ie, 54% bigger blocks (higher volume or more transaction) each year could support about 2.37 higher price each year.
  • 2.37x annual price growth for 8 years would be 2.378 = 2.37 * 2.37 * 2.37 * 2.37 * 2.37 * 2.37 * 2.37 * 2.37 = 1000 - giving a price of 1 BTC = 1 million USDollars if the price increases an average of 2.37x per year for 8 years, starting from 1 BTC = 1000 USD now.
So, even though initially it might seem crazy to think that we could get to 1 BTC = 1 million USDollars in 8 years, it's actually not that far-fetched at all - based on:
  • some simple math,
  • the observed available bandwidth (already increasing at 70% per year), and
  • the increasing fragility and failures of many "legacy" debt-backed national fiat currencies and payment systems.
Does Metcalfe's Law hold for Bitcoin?
The past 8 years of data suggest that Metcalfe's Law really does hold for Bitcoin - you can check out some of the graphs here:

(3) Satoshi's original 32MB "max blocksize" would provide an ultra-simple, ultra-safe, non-controversial approach which perhaps everyone could agree on: Bitcoin's original promise of "p2p electronic cash", 100% on-chain, eventually worth 1 BTC = 1 million dollars.
This could all be done using only the whitepaper - eg, no need for possibly "controversial" changes like SegWit/Lightning, Bitcoin Unlimited, etc.
As we know, the Bitcoin community has been fighting a lot lately - mainly about various controversial scaling proposals.
Some people are worried about SegWit, because:
  • It's actually not much of a scaling proposal - it would only give 1.7MB blocks, and only if everyone adopts it, and based on some fancy, questionable blocksize or new "block weight" accounting;
  • It would be implemented as an overly complicated and anti-democratic "soft" fork - depriving people of their right to vote via a much simpler and safer "hard" fork, and adding massive and unnecessary "technical debt" to Bitcoin's codebase (for example, dangerously making all UTXOs "anyone-can-spend", making future upgrades much more difficult - but giving long-term "job security" to Core/Blockstream devs);
  • It would require rewriting (and testing!) thousands of lines of code for existing wallets, exchanges and businesses;
  • It would introduce an arbitrary 1-to-4 "discount" favoring some kinds of transactions over others.
And some people are worried about Lightning, because:
  • There is no decentralized (p2p) routing in Lightning, so Lightning would be a terrible step backwards to the "bad old days" of centralized, censorable hubs or "crypto banks";
  • Your funds "locked" in a Lightning channel could be stolen if you don't constantly monitor them;
  • Lighting would steal fees from miners, and make on-chain p2p transactions prohibitively expensive, basically destroying Satoshi's p2p network, and turning it into SWIFT.
And some people are worried about Bitcoin Unlimited, because:
  • Bitcoin Unlimited extends the notion of Nakamoto Consensus to the blocksize itself, introducing the new parameters EB (Excess Blocksize) and AD (Acceptance Depth);
  • Bitcoin Unlimited has a new, smaller dev team.
(Note: Out of all the current scaling proposals available, I support Bitcoin Unlimited - because its extension of Nakamoto Consensus to include the blocksize has been shown to work, and because Bitcoin Unlimited is actually already coded and running on about 25% of the network.)
It is normal for reasonable people to have the above "concerns"!
But what if we could get to 1 BTC = 1 million USDollars - without introducing any controversial new changes or discounts or consensus rules or game theory?
What if we could get to 1 BTC = 1 million USDollars using just the whitepaper itself - by simply reinstating Satoshi's original 32MB "max blocksize"?
(4) We can easily reach "million-dollar bitcoin" by gradually and safely growing blocks to 32MB - Satoshi's original "max blocksize" - without changing anything else in the system!
If we simply reinstate "Bitcoin Original" (Satoshi's original 32MB blocksize), then we could avoid all the above "controversial" changes to Bitcoin - and the following 8-year scenario would be quite realistic:
  • Actual blocksizes growing modestly at 54% per year - well within the 70% increase in available "provisioned bandwidth" which we actually happened last year
  • This would give us a reasonable, totally feasible blocksize of 1.548 = 32MB ... after 8 years.
  • Bitcoin price growing at 2.37x per year, or a total increase of 2.378 = 1000x over the next 8 years - which is similar to what happened during the previous 8 years, when the price went from under 1 USDollars to over 1000 USDollars.
  • This would give us a possible Bitcoin price of 1 BTC = 1 million USDollars after 8 years.
  • There would still be plenty of decentralization - plenty of fully-validating nodes and mining nodes), because:
    • The Cornell study showed that 90% of nodes could already handle 4MB blocks - and that was several years ago (so we could already handle blocks even bigger than 4MB now).
    • 70% yearly increase in available bandwidth, combined with a mere 54% yearly increase in used bandwidth (plus new "block compression" technologies such as XThin and Compact Blocks) mean that nearly all existing nodes could easily handle 32MB blocks after 8 years; and
    • The "economic incentives" to run a node would be strong if the price were steadily rising to 1 BTC = 1 million USDollars
    • This would give a total market cap of 20 trillion USDollars after about 8 years - comparable to the total "money" in the world which some estimates put at around 82 trillion USDollars.
So maybe we should consider the idea of reinstating Satoshi's Original Bitcoin with its 32MB blocksize - using just the whitepaper and avoiding controversial changes - so we could re-unite the community to get to "million-dollar bitcoin" (and 20 trillion dollar market cap) in as little as 8 years.

Why Verge Needs DigiShield NOW! And Why DigiByte Is SAFE!

Hello everyone, I’m back! Someone asked a question recently on what exactly happened to XVG – Verge and if this could be a problem for DGB – DigiByte - Here: DigiByte vs Verge It was a great question and there have been people stating that this cannot be a problem for us because of DigiShield etc… with not much explanation after that.
I was curious and did a bit more investigating to figure out what happened and why exactly it is that we are safe. So take a read.

Some Information on Verge

Verge was founded in 2014 with code based on DogeCoin, it was initially named DogeCoinDark, it later was renamed Verge XVG in 2016. Verge has 5 mining algorithms as does DigiByte. Those being:
However, unlike DigiByte those algorithms do not run side by side. On Verge one block can only be mined by a single algorithm at any time. This means that each algorithm takes turns mining the chain.
Prior to the latest fork there was not a single line of code that forced any algo rotation. They all run in parallel but of course in the end only one block can be accepted at given height which is obvious. After the fork algo rotation is forced so only 6 blocks with the same algo out of any 10 blocks can be accepted. - srgn_

Mining Verge and The Exploit

What happened then was not a 51% attack per say, but the attacker did end up mining 99% of all new blocks so in fact he did have power of over 51% of the chain. The way that Verge is mined allowed for a timestamp exploit. Every block that is mined is dependent on the previous blocks for determining the algorithm to be used (this is part of the exploit). Also, their mining difficulty is adjusted every block (which last 30 seconds also part of the exploit). Algorithms are not picked but in fact as stated previously compete with one another. As for difficulty:
Difficulty is calculated by a version of DGW which is based on timestamps of last 12 blocks mined by the same algo. - srgn_
This kind of bug is very serious and at the foundation of Verge’s codebase. In fact, in order to fix it a fork is needed, either hard fork or soft fork!
What happened was that the hacker managed to change the time stamps on his blocks. He introduced a pair of false blocks. One which showed that the scrypt mining algorithm had been previously used, about 26 mins before, and then a second block which was mined with scrypt. The chain is set up so that it goes through the 5 different algorithms. So, the first false block shows the chain that the scrypt algorithm had been used in the recent past. This tricks it into thinking that the next algorithm to be used is scrypt. In this way, he was essentially able to mine 99% of all blocks.
Pairs of blocks are used to lower the difficulty but they need to be mined in certain order so they can pass the check of median timestamp of last 11 blocks which is performed in CBlock::AcceptBlock(). There is no tricking anything into thinking that the next algo should be x because there is no algo picking. They all just run and mine blocks constantly. There is only lowering the difficulty, passing the checks so the chain is valid and accepting this chain over chains mined by other algos. - segn_
Here is a snippet of code for what the time stamps on the blocks would look like:
SetBestChain: new best=00000000049c2d3329a3 height=2009406 trust=2009407 date=04/04/18 13:50:09 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000a307b54dfcf height=2009407 trust=2009408 date=04/04/18 12:16:51 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=00000000196f03f5727e height=2009408 trust=2009409 date=04/04/18 13:50:10 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=0000000010b42973b6ec height=2009409 trust=2009410 date=04/04/18 12:16:52 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000e0655294c73 height=2009410 trust=2009411 date=04/04/18 12:16:53 ProcessBlock: ACCEPTED (scrypt) 
Here’s the first falsified block that was introduced into the XVG chain – Verge-Blockchain.info
As you can see there is the first fake block with a time stamp of 13:50:09 for example and the next is set to 12:15:51, the following two blocks are also a fraudulent pair and note that the next block is set to 12:16:52. So essentially, he was able to mine whole blocks - 1 second per block!

The “Fix”

This exploit was brought to public attention by ocminer on the bitcointalk forums. It seems the person was a mining pool administrator and noticed the problem after miners on the pool started to complain about a potential bug.
What happened next was that Verge developers pushed out a “fix” but in fact did not really fix the issue. What they did was simply diminish the time frame in which the blocks can be mined. The attack still was exploitable and the attacker even went on to try it again!
“The background is that the "fix" promoted by the devs simply won't fix the problem. It will just make the timeframe smaller in which the blocks can be mined / spoofed and the attack will still work, just be a bit slower.” - ocminer
Ocminer then cited DigiShield as a real fix to the issue! Stating that the fix should also stipulate that a single algo can only be used X amount of times and not be dependent on when the algo was last used. He even said that DigiByte and Myriad had the same problems and we fixed them! He cited this github repo for DigiByte:

DigiShield

It seems that the reason that this exploit was so lucrative was because the difficulty adjustment parameters were not enough to reduce the rewards the attacker recieved. Had the rewards per block adjusted at reasonable rate like we do in DGB then at least the rewards would have dropped significantly per block.
The attacker was able to make off with around 60 million Verge which equals about 3.6 million dollars per today’s prices.
The exploit used by the attacker depended on the fact that time stamps could be falsified firstly and secondly that the difficulty retargeting parameters were inadequate.
Let’s cover how DigiShield works more in detail. One of the DigiByte devs gave us this post about 4 years ago now, and the topic deserves revisiting and updates! I had a hard time finding good new resources and information on the details of DigiShield so I hope you’ll appreciate this review! This is everything I found for now that I could understand hopefully I get more information later and I’ll update this post.
Let’s go over some stuff on difficulty first then I’ll try giving you a way to visualise the way these systems work.
First you have to understand that mining difficulty changes over time; it has to! Look at Bitcoin’s difficulty for example – Bitcoin difficulty over the past five months. As I covered in another post (An Introduction to DigiByte Difficulty in Bitcoin is readjusted every 2016 blocks which each last about 10 mins each. This can play out over a span of 2 weeks, and that’s why you see Bitcoin’s difficulty graph as a step graph. In general, the hash power in the network increases over time as more people want to mine Bitcoin and thus the difficulty must also increase so that rewards are proportional.
The problem with non-dynamic difficulty adjustment is that it allows for pools of miners and or single entities to come into smaller coins and mine them continuously, they essentially get “free” or easily mined coins as the difficulty has not had time to adjust. This is not really a problem for Bitcoin or other large coins as they always have a lot of miners running on their chains but for smaller coins and a few years ago in crypto basically any coin other than Bitcoin was vulnerable. Once the miners had gotten their “free coins” they could then dump the chain and go mine something else – because the difficulty had adjusted. Often chains were left frozen or with very high fees and slow processing times as there was not enough hash power to mine the transactions.
This was a big problem in the beginning with DigiByte and almost even killed DogeCoin. This is where our brilliant developers came in and created DigiShield (first known as MultiShield).
These three articles are where most of my information came from for DigiShield I had to reread a the first one a few times to understand so please correct me if I make any mistakes! They are in order from most recent to oldest and also in order of relevance.
DigiShield is a system whereby the difficulty for mining DigiByte is adjusted dynamically. Every single block each at 15 seconds has difficulty adjusted for the available hashing power. This means that difficulty in DigiByte is as close as we can get to real time! There are other methods for adjusting difficulty, the first being the Bitcoin/Litecoin method (a moving average calculated every X number of blocks) then the Kimoto Gravity Well is another. The reason that DigiShield is so great is because the parameters are just right for the difficulty to be able to rise and fall in proportion to the amount of hash power available.
Note that Verge used a difficulty adjustment protocol more similar to that of DigiByte than Bitcoin. Difficulty was adjusted every block at 30 seconds. So why was Verge vulnerable to this attack? As I stated before Verge had a bug that allowed for firstly the manipulation of time stamps, and secondly did not adjust difficulty ideally.
You have to try to imagine that difficulty adjustment chases hashing power. This is because the hashing power on a chain can be seen as the “input” and the difficulty adjustment as the corresponding output. The adjustment or output created is thus dependent on the amount of hashing power input.
DigiShield was designed so that increases in mining difficulty are slightly harder to result than decreases in mining difficulty. This asymmetrical approach allows for mining to be more stable on DigiByte than other coins who use a symmetrical approach. It is a very delicate balancing act which requires the right approach or else the system breaks! Either the chain may freeze if hash power increases and then dumps or mining rewards are too high because the difficulty is not set high enough!
If you’ve ever taken any physics courses maybe one way you can understand DigiShield is if I were to define it as a dynamic asymmetrical oscillation dampener. What does this mean? Let’s cover it in simple terms, it’s difficult to understand and for me it was easier to visualise. Imagine something like this, click on it it’s a video: Caravan Weight Distribution – made easy. This is not a perfect analogy to what DigiShield does but I’ll explain my idea.
The input (hashing power) and the output (difficulty adjustment) both result in oscillations of the mining reward. These two variables are what controls mining rewards! So that caravan shaking violently back and forth imagine those are mining rewards, the weights are the parameters used for difficulty adjustment and the man’s hand pushing on the system is the hashing power. Mining rewards move back and forth (up and down) depending on the weight distribution (difficulty adjustment parameters) and the strength of the push (the amount of hashing power input to the system).
Here is a quote from the dev’s article.
“The secret to DigiShield is an asymmetrical approach to difficulty re-targeting. With DigiShield, the difficulty is allowed to decrease in larger movements than it is allowed to increase from block to block. This keeps a blockchain from getting "stuck" i.e., not finding the next block for several hours following a major drop in the net hash of coin. It is all a balancing act. You need to allow the difficulty to increase enough between blocks to catch up to a sudden spike in net hash, but not enough to accidentally send the difficulty sky high when two miners get lucky and find blocks back to back.”
AND to top it all off the solution to Verge’s time stamp manipulation bug is RIGHT HERE in DigiShield again! This was patched and in Digishield v3 problems #7
Here’s a direct quote:
“Most DigiShield v3 implementations do not get data from the most recent blocks, but begin the averaging at the MTP, which is typically 6 blocks in the past. This is ostensibly done to prevent timestamp manipulation of the difficulty.”
Moreover, DigiShield does not allow for one algorithm to mine more than 5 blocks in a row. If the next block comes in on the same algorithm then it would be blocked and would be handed off to the next algorithm.
DigiShield is a beautiful delicate yet robust system designed to prevent abuse and allow stability in mining! Many coins have adopted out technology!

Verge Needs DigiShield NOW!

The attacker has been identified as IDCToken on the bitcointalk forums. He posted recently that there are two more exploits still available in Verge which would allow for similar attacks! He said this:
“Can confirm it is still exploitable, will not abuse it futher myself but fix this problem immediately I'll give Verge some hours to solve this otherwise I'll make this public and another unpatchable problem.” - IDCToken
DigiShield could have stopped the time stamp manipulation exploit, and stopped the attacker from getting unjust rewards! Maybe a look at Verge’s difficulty chart might give a good idea of what 1 single person was able to do to a coin worth about 1 billion dollars.
Here’s DigiByte’s difficulty steady, even and fair:
Maybe our developers could help Verge somehow – but for a fee? Or it might be a good way to get our name out there, and show people why DigiByte and DigiShield are so important!

Edit - Made a few mistakes in understanding how Verge is mined I've updated the post and left the mistakes visible. Nothing else is changed and my point still stands Verge could stand to gain something from adopting DigiShield!
Hi,
I hope you’ve enjoyed my article! I tried to learn as much as I could on DigiShield because I thought it was an interesting question and to help put together our DGB paper! hopefully I made no mistakes and if I did please let me know.
