Bitcoin Cash (BCH) is a digital cryptocurrency that was created as a result of a hard fork from the original Bitcoin (BTC) network. Bitcoin Cash was designed to address certain limitations of Bitcoin, primarily related to scalability and transaction speed. The key difference between Bitcoin Cash and Bitcoin lies in their block size limit.
Bitcoin has a block size limit of 1 megabyte (MB), which can restrict the number of transactions processed per block and cause delays and high transaction fees during periods of increased demand. Bitcoin Cash, on the other hand, increased the block size limit to 8 MB initially, and later increased it further to 32 MB through a subsequent hard fork.
