That may be so, but there are still very few places where you can spend BCH. And those big blocks are still mostly empty. BCH has yet to prove that big blocks are safe for the network. If big blocks are eventually proven to be safe, increasing the blocksize (perhaps by a more conservative amount) is something that core could easily adopt, negating any advantage of BCH.
That's really an understatement. I haven't seen or heard of any store that would accept BCH. It's being used only as a conversion coin good for speculation when BTC is correcting. People somehow tend to think that if BTC fails BCH will take over. It won't happen. If BTC fails and loses most of its value some of the money will surely go to BCC , but it will be a dark moment for all cryptocurrencies. If BTC dies people will lose confidence in cryptos and the whole market will crash which will of course include altcoins and IMO the forked coins will suffer the most as people will look for hope in the more anonymous or government issued cryptos.
