Bitcoin Cash is a cryptocurrency. A group of developers who wanted to raise the block size limit of Bitcoin prepared a code shift in mid-2017. The shift, which was called a hard fork, came into effect on August 1, 2017. As a result, the Bitcoin ledger called the blockchain and the cryptocurrency split into two. At the time of the fork anyone who owned Bitcoin was also in possession of the same number of Bitcoin Cash units. The technical difference between Bitcoin Cash and Bitcoin is that Bitcoin Cash allows larger blocks in its blockchain than Bitcoin, which theoretically allows more transactions per second to be processed. Bitcoin Cash divided into two cryptocurrencies on November 15, 2018.
