Here's why it won't:
The total hashrate on the BCH network is around 11 times lower than the total hashrate on BTC's network.
The difficulty right now is about 6 times lower than BTC, but there will be an increase soon and the difficulty might triple.
If the difficulty triples, BTC's difficulty will be about 2.5 times than that of BCH.
Also, when the difficulty triples, I think some people are gonna leave and mine something else as it will become much less profitable.
Just hope the transactions don't start slowing down, if they do, that's the end of BCH.
BCH will not be able to surpass BTC, BTC is still at the top, far away from what BCH can do. As some people say, it's just another pump, BCH won't be competing with BTC anytime soon.
