Bitcoin Cash(BCH) is a hard fork of Bitcoin due to disagreements in the Bitcoin community regarding the use of the coin. BCH aims to achieve Nakamoto's original vision of Bitcoin as a digital currency rather than an investment or store of value. Due to the rise of popularity of Bitcoin, transaction fees and confirmation time have skyrocketed. This is due to the limitation of the block size for Bitcoin which is 1MB per block. To solve this issue, BCH changed the block size and thus forked from the main Bitcoin blockchain.
