I believe that bitcoin cash is just a speculative coin. The difference between the data and the crypto currency is that bitcoin has a block size of 1 mb, and bitcoin cash has increased the block size to 8 mb. However, this does not solve the problem with the bandwidth of the network. Therefore, I believe that bitcoin is better, as a symbol of crypto currency, that it was the first.
All coins are speculative, users by and sell them hoping to make money that is all. Doing it at the right time will bring profit, otherwise it will be a loss.
