Huobi at 496... stamp at 490. what's the problem? the market was falling before all the announcements..... just a natural correction.
Don't you think its even a little bit suspicious that each of these announcements is preceded by a large dump, right before the news is made public?
And what you / we can do about that?
Remember that if they are not doing it intentionaly, they would be stupid to not take advantage of this insider info.
