Utility will win, but as said by sharpshot below, BTC has supremacy in terms of recognition at this point. The point is that competition will win out IF the BTC network does not solve the utility issues I summarized. Right now, I'd still bet on BTC, but hedging your bets with BCH and other alt coins is not a bad idea. Remember to watch your position sizes, because a lot of coins will simply go away in the end. That means go to zero! Not a fun ride to take.
