BTC actually has significant advantages over Bitcoin Cash, even if it has higher fees and transaction times, simply because it's the common denominator for literally every altcoin.
This is one of the least important advantages. The main one is segwit which gives entirely new horizon in addition to what we already had before it..
Pretty sure the fact that there's a $100bn altcoin market would imply that Segwit is going to be the next coming of Jesus. Is that what you are saying?
