If we look at the history of cryptocurrencies, we all know that Bitcoin is the first, most famous and most valuable cryptocurrency. But in 2017, his younger brother Bitcoin Cash (BCH) was created, which is more advanced and better for transactions in many characteristics. The cryptocurrency Bitcoin Cash was created thanks to the hardfork in the Bitcoin network, and the name itself was given to it because of its idea to be used as digital money, while Bitcoin is digital gold. In terms of similarities, Bitcoin Cash and Bitcoin are of course very similar, but with a few differences. The biggest difference is that the block size of Bitcoin Cash is much larger. When it started working, then the block size was 8MB, and after one system upgrade, the block size increased to an incredible 32MB.
