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.
I don't think BCH will replace bitcoin. Come on, bitcoin has a solid community already and they are solid as believers in this crypto. If you could break the solid supporters of bitcoin maybe that's the time bitcoin will be replaced by other coins but I don't think it is BCH. Sorry but I am not a supporter of bitcoin cash.
