Bitcoin Cash (BCH) is a decentralized cryptocurrency created in 2017 through a hard fork of the Bitcoin blockchain. It has a larger block size than Bitcoin, allowing for faster and cheaper transactions. Bitcoin Cash can be used as a means of exchange and store of value and is gaining acceptance among merchants and businesses worldwide. It was created by a group of developers and miners who believed that Bitcoin needed modifications to address scalability issues. The main developer team was initially called "Bitcoin ABC," but development has since become more decentralized.
