Some people are saying BCH will supersede BTC. This has folks worried that they backed the wrong horse when they bought BTC over BCH.
Thats like saying because we own silver, we shouldnt bother with gold. The market is big enough for both BTC and BCH.
While BTC may not be able to scale (yet), the BCH scaling solution is not without its drawbacks either.
Many people will not have too much of a problem with bitcoin cash if it did not promote itself as the real bitcoin, there is space for both of them but I think that is what has bothered people the most, and with the recent pump in the price we could see the price is being heavily manipulated by whales and the miners and that does not add any credibility to bitcoin cash.
