I have a feeling it was 1 guy who forked a bunch of altcoins , put them on the exchanges, made a ton of money and then got out.
We know that guy and he's also from the forum. And then followed by CSW and both of them fighting that either of their forks were the real Bitcoin. But none of them who's saying the truth. Because Bitcoin is the real Bitcoin and none of their forks are the real one. Although it's no doubt that both of them have made a lot of money because they just forked it and made money out of thin air while keeping the real BTCs that they have been holding.
