Bitcoin Cash is the most popular Bitcoin hard fork proposed by Roger Ver in 2017 as a solution to the problem of slow transactions in the Bitcoin network. The idea was to create a version of Bitcoin that would be better for payments, while original Bitcoin is considered more as a store of value. Bitcoin Cash has a bigger block size than Bitcoin so the transactions of this currency are faster and cheaper.

Bitcoin Cash quickly attracted a huge following and became a prominent part of the cryptocurrency market. BCH is available on many exchanges and is supported by numerous crypto services. Since the launch of the project, it has never left the top 10.
