Currently Bitcoin is sitting at $6600 which is only 13% lower than the ATH. Meanwhile, BCH has crashed 3 times lower from its short-lived, artificial ATH, because it wasn't actual users who switched from BTC to BCH, but merely individual manipulators with big pockets who decided to attack Bitcoin regardless of decision of their comrades to cancel another attack called SegWit2x. People were declaring Bitcoin dead hundreds of times already, yet with every year its value keeps increasing and userbase growing.
