I don't think BCASH will replace BTC ever, also I don't believe in it at all purely because of Roger Ver being involved in it. I stay away from projects which Roger Ver publicly advertise, just like the recent token MoneyToken being advertised by him. They gain lots of money in ICO purely because he was involved in it and I'm pretty sure he must have gotten the MoneyToken tokens at atleast 90% discount than ICO price. Moreover there's no surety when he'll sell his all holdings in support of new fork which his team will create. He is a shit person in this crypto space, better to stay away from such people.
