Bitcoin Cash (BCH) is a cryptocurrency that was created in 2017 as a hard fork of Bitcoin (BTC) to address scalability issues and enhance transaction speeds. It increases the block size limit from 1 MB to 8 MB (and later to 32 MB), allowing more transactions to be processed per block and reducing transaction fees. Bitcoin Cash aims to serve as a more practical and efficient medium of exchange for everyday transactions, maintaining the core principles of decentralization and security while offering improved performance compared to its predecessor.
