Bitcoin Cash is an alternative to Bitcoin that aims to fix the main issues that Bitcoin suffers from by changing how the blockchain behaves. The biggest changes are that Bitcoin Cash has a faster block time and larger blocks. That means transactions go through faster and cheaper than they would on the Bitcoin network.
When demand is high, Bitcoin Cash transactions can become slow due to the relatively small size of each block and the fact that each block takes about 10 minutes to complete. This could translate into a long wait time of hours or even days for a transaction to go through. It can also result in a much higher transaction fee to move your transaction to the front of the line.
However, with Bitcoin Cash’s faster block times and larger block sizes, fees are consistently low, and transactions generally take minutes to finalize.
BTC and BCH are not interchangeable and are completely different cryptocurrencies with their own blockchains. The maximum supply of Bitcoin Cash is 21 million, identical to that of BTC. Additionally, Bitcoin Cash has its own blockchain and is, therefore, a coin rather than a token.
