wasn't it enough that he admitted he is receiving a lot of money to advertise ICOs?
I think this guy is one of those whales who technically played with bitcoin's price, that's we've experienced roller coaster situation nowadays. Even if he admitted receiving money from lots of advertised ICOs, there's no way for us to stop this guy, because he's so fortunate now and had more assets that we are. We should hope that the popularity of bitcoin will rise again so that whales could take over the peak price and the whales again will help the price to pump, because its a great opportunity for the smaller fish to catch their profit.
However, controlling everyone's emotions depends on how they understand the real scenario. If they always remain in chaos while the price started to declined quickly it won't help gain confidence holding for a long time. That's why if you decide of dumping your coins quickly, well certainly you lose it and emotional stress can be your worst enemy if a trader couldn't move on. You might see the price to gain its profitable value after all because eventually it will develop its momentum after the dumping price, yet the reality really proves it since last year's experiences.
