Bitcoin Cash, Ethereum Classis, Litecoin King, Dash Queen, whatever duplicate names they give themselves have NO FUTURE. They're just trading robots with no concepts behind them. They're just replica of the BIG names in the market.
Are you serious?
I think you're misunderstanding the concept of a fork.
As for BCH, I concluded for myself that it is in theory the better coin, at least, technically. Unlike BTC, it can function with low fees even when the hashing power gets lower, as where with BTC you end up paying enormous fees or have to wait hours for your transaction to pass. Segwit did not change much in this regard.
Everyone has such a blind faith in BTC I find it unreal. Just because every altcoin gets mostly traded with BTC doesn't mean BTC will stay on top forever. What goes up goes down at some point and I guarantee you BTC will crash hard at some point.
But hey, everyone is free to do what he wants with his money. I just wouldn't bet it all on BTC.
BCH just lacks the real world usage for now. We'll see what happens once it gets offered as a payment method on the big market places out there (if ever).
I'd buy a bit of BCH on the side now if I had some funds available.
