I do not think that BCH will replace BTC because the BCH has nothing more than block size than BTC, that does not make much sense, it's ridiculous that many cryptocurrency bots say replace BTC but I It is hard to replace the legendary BTC symbol
I agree. BTC is a very strong coin and will be coin number 1 for a very long time. And BCH will not replace BTC. BTC for a long time will be the most reliable coin for investment.
