Well, you can be sure that they made enough money from bitcoin cash.
They mined bitcoin cash even when it was unprofitable to mine, because later they made an organized pump and they were managed to push it to 0.5BTC at most of the exchanges which is completely crazy.
Bitcoin cash is being completely controlled by the chinese strong players, it's a centralized coin that is being used for manipulations only.
Bitcoin for sure. Bitcoin cash and other similar coins are only made due to forks, or at least, are made as copies of Bitcoin. And as we all know, it's always the original that prospers. I am not saying that in consideration of the point of origin, like for example with NEO and ETH, many say that since NEO is the China copy of ETH that it's not better, I don't share that belief because copy or not, it has it's own technology at its back and it also has their own following of people who support them, it's just that people trust the original more.
