On May 23, 2017, 58 well-known blockchain companies from 22 countries around the world jointly signed the New York Consensus (Segwit2x, that is, Segregated Witness + 2M), and the New York Consensus obtained 83.28% of the entire network's computing power signature support , the trading platforms with a total transaction volume of more than 5.1 billion US dollars per month and more than 20 million bitcoin wallets agreed to implement the consensus plan: unanimously agree to upgrade Segwit first, and upgrade the block size to 2M within 6 months . Segwit was officially activated on July 23, 2017. According to the established plan, 90 days after the completion of Segwit activation (Bitcoin blockchain time), Bitcoin miners will freely decide to mine 1MB or 2MB blocks. Therefore, it is expected that in November On the 19th, Bitcoin Segwit2x fork may occur. In the face of the upcoming Bitcoin Segwit2x hard fork in November, major trading platforms have begun to release solutions in these two days in order to respond in a timely manner. Most trading platforms list all the coins, and then look at the market and user choices, allowing users to make their own decisions.
