I think regrettable that Bitcoin cash will replace Bitcoin in the future (1-2 years), at least in price
Bch cash is an improved version of btc, and has 8mb blocks, in the future, if cryptos uses in day of day of real life, btc isn't optimized to make so transactions per second, and i'm afraid.
At the moment I think bitcoin cash has lost its value and will lose its value in the market, even I think now you can see it, bitcoin has created this market and will dominate it
the dominant power is still in the hands of Bitcoin so Bitcoin cash is not in your good stage So definitely the most powerful currency in Crypto market is bitcoin only.
