In my experience bitcoin cash is a fork of bitcoin even BCH is faster and cheaper to use due to larger blocks but still it'a seen that most of the people are using BTC than BCH so why is bitcoin doing better than bitcoin cash?
it's older and kinda of more reliable. also btc could be named as too big to fail.
for me personally, Bitcoin has ceased to be attractive, not to mention Bitcoin cash. The fact is that the most economically attractive and demanded coin should be etherium and I hope that in the near future the situation will be like that.
it also seems to me that eth will take the lead, but in this comparison between btc and bch btc is undoubtedly more stable.
