This is not really good. It seems it is common knowledge here that this has been happening. But I am actually just coming across this sort of news for the first time. I think the Blockchain technology is a really genius innovation. But if such manipulations continue in the crypto market, then it's a bad thing. Serious action will definitely be taken soon. It is only a matter of time. Even if legal action is not taken, this discovery will discourage investors in the long run.
