Bitcoin crashed more than 25% from Wednesday's all-time high to a low of $5,617 Sunday. Bitcoin cash, the rival clone of bitcoin, witnessed an impressive rally that propelled the coin to a record-high of $2,500 early Sunday morning.
24-hour trading volumes for cryptocurrencies reached a record high above $26 billion on Sunday, according to data site CoinMarketCap.com.
To put that in perspective, that is higher than the 5-day average trading volumes for two US stock exchanges. Both IEX, the upstart exchange based in New York, and the Chicago Stock Exchange averaged less than $10 billion in trading each day for the last five days, according to data by Cboe Global Markets.
IEX saw $7.8 billion worth of shares exchange on its venue, whereas CHX witness $3.1 billion in trading volumes.

Bitcoin's High Transaction Fees Show Its Limits
The Bitcoin rate spike, still alive despite bitter divisions in the community that supports the cryptocurrency, has laid bare the biggest problem with Bitcoin: Compared with fiat currencies, it's painfully inconvenient and expensive to use as a means of payment.
Bitcoin is set up to reward users for verifying transactions. Miners who package transactions into "blocks" receive two kinds of rewards: The additional Bitcoin they produce by using their hardware to solve mathematical problems (an income stream that will eventually cease since 21 million bitcoins are the maximum that can be mined) and the transaction fees paid by users to get their payments into blocks.
The Bitcoin system is designed around scarcity and its traditionalists insist on keeping the block size small (rebels who did away with that tenet founded an offshoot, Bitcoin Cash, earlier this year). Their reasoning is that only people with more computing power can live in a big-block world and going down that path would make Bitcoin less democratic. But that horse has bolted: Mining is already largely the province of people who invest significant money in equipment and the huge amount of energy required to run it. As Bitcoin's exchange rate rose rapidly and more people wanted to get in on the boom, getting into blocks became difficult, and miners prioritize transactions on which users are willing to pay a higher fee. It works a bit like Uber's surge pricing, except the user sets the fee based on how long she's prepared to wait for the transaction to go through -- using one of several sites that link fees to waiting times or show median and average fees.

Bitcoin Cash Network Completes a Successful Hard Fork
November 13 is a memorable day for bitcoin cashsupporters, as the network is forking in order to fix the BCH blockchain’s DAA. The primary development teams who have been working on the bitcoin cash protocol consensus change include Bitcoin ABC, Unlimited, Nchain, and XT developers. The original DAA applied to the BCH network allowed the currency to thrive but also produced wild hashrate fluctuations. After several DAA proposals were researched and tested by the above-mentioned development teams, the community chose to implement a DAA proposal from Bitcoin ABC’s lead developer Amaury Sechet.
The new BCH consensus change hopes to adjust the difficulty to hashrate to target a mean block interval of 600 seconds. Alongside this, the DAA aims to make sudden difficulty drops and spikes avoidable. For instance, the network will adjust difficulty rapidly when the hashrate changes exponentially, while also avoiding feedback oscillations. Sechet’s DAA is based on a 144-period simple moving average according to the ABC team.
“The difficulty is adjusted each block, based on the amount of work done and the elapsed time of the previous 144 blocks,” explains the Bitcoin ABC development team.
Essentially the consensus change means the new DAA should keep block times stable and consistent at roughly 10 minutes per block. So far this goal of 10-minute block intervals has come to fruition. Now that the fork has happened BCH network participants will wait and see what happens with miners who have been hopping back and forth between two chains. Many BCH supporters believe this will level the playing field and from here on out, as the BTC and BCH competition should be fair without any miners gaming the system.

CME CEO: Bitcoin Futures Could Begin Trading As Soon As December
CME Group chairman and CEO Terry Duffy has said that the derivatives exchange operator could list a planned bitcoin futures product as early as next month.
Speaking to CNBC today, Duffy said that trading could begin as early as the second week of December.
"I think sometime in the second week of December you'll see our contract out for listing," he told the network.
The firm made waves in October when it revealed that it was seeking regulatory approval to list its first bitcoin-related product. At the time, CME said that the futures would be tied to its existing price index, launched in 2016, and be settled via cash.
