The would-be hard fork with an expanded block size limit was described by hardware manufacturer Bitmain in June 2017 as a "contingency plan" should the Bitcoin community decide to fork; the first implementation of the software was proposed under the name Bitcoin ABC at a conference that month. In July 2017, the Bitcoin Cash name was proposed by mining pool ViaBTC.

Like email, bitcoin is a protocol. Where email is a protocol for sending messages over the internet, bitcoin is a protocol for sending money over the internet. The bitcoin protocol defines the rules of a payment network, called bitcoin, that uses a currency, also called bitcoin, to pay computers around the world for securing the network. The software that implements the bitcoin protocol uses a special branch of mathematics called cryptography to ensure the security of every bitcoin transaction.

Which brings us to Bitcoin SV’s main "weapon" — perhaps literally. At the time of writing, all the biggest Bitcoin Cash mining pools are supportive of Bitcoin SV. Calvin Ayre’s private CoinGeek pool, Wright and nChain’s public SVPool, nChain’s private BMG Pool as well as Okminer and Mempool all favor Bitcoin SV, representing up to 60 or 70 percent of hash power. The rest of the pools — a minority — are either neutral (for example planning to follow majority hash power) or in favor of Bitcoin ABC.
Second, two coins could survive the split, both with their own name and ticker. (In this case Bitcoin ABC seems most likely to get the name “Bitcoin Cash” and “BCH,” but this could differ from one service to the next.) This is where you need to be particularly careful, as there’s no replay protection. When you send one coin you may unintentionally send the other along with it — or vice versa. To avoid this, you need to first split your coins by using a splitting tool, for example, or by sending your coins to an exchange or other type of service that will split the coins and send both back independently. (Again, there’s no rush to do any of this. Until you know what you’re doing, it’s best to do nothing at all.)
The company is officially registered in the UK, has a Money Services Business status in FinCEN (USA), which means that we are recognized on the international level. At the same time, CEX.IO pays much attention to the issues of security, and the strong anti-DDoS protection as well as level 2 PCI DSS evidence that the service ensures the security of customers’ funds and personal data. In addition, two-factor authentication also contributes to the overall safety of the platform.
