the other problem is that the segwit upgrade isn't being used by big exchanges, so BTC is for all intents and purposes still running legacy code with 1MB blocks for a vast majority of transactions. This is really what is killing core, because trying to upgrade code that depends on the users is going to be a battle against the exchanges, while upgrading the block size with BCH is a done move that requires no cooperation. While I think BCH is more effective in the short term, I also think Roger Ver is an ass.
