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.
Are you sure about your statement? Even newbies know that what you're saying is a false. No one can replace BTC with a short period of time, what you're saying is just 1 or 2 years which is imposible.
