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.
Bitcoin is still having dominance over btc. Had it been it is independent of the influence of btc, that would have made me to agree on that, but the case here is quite different
No matter the negative effect that might have been felt before, it will be over at a point and things will get better.
