no matter what happens after a thousands years BCH will still remain the coin that split from bitcoin to create a useless altcoin. it is copy of bitcoin without the additional benefits. so it is a shorter copy of it.

it doesn't have any future, it is a centralized altcoin with no usage and nothing to offer. when it comes to altcoins your competition becomes much harder because you are not competing with nearly 2000 different competitors and some of them are very strong even though they may have lower prices right now.
