BCH/Bcash is extremely centralized. Everything over there in terms of protocal development will be top down! It's totally governed and has nothing to do with Bitcoin.Therefore sooner or later there will be some form of censorship. In no way this coin will have any more value than Bitcoin or coming close to it. But it will survive and maybe become a government coin, China for instance I could imagine taking an initiative. I have really hard times believing that Jihan can act however he wants. I'm sure the chinese government is pretty close to him in one way or the other.
Sorry but I really and strongly don't recognize that BCC in terms of how it will overpower BTC by 2020, because for me it was just like a bubble for who popped up after that so called fork which scared a lot of investors. Whatever it takes bitcoin will remains standing firm by it pillars of foundation and will gain good price by that years of 2020 to come soon and we are near closer to it by next year it's already 2018; so we have two more years to go further.
