Has Jacky popped up yet at a new job? He probably has a cushy gig in the Caymans working for a hedge fund. This is not delusional, it is the first thing I would do as a fund manager with a big stake in this game. The guy was making $80k, easily bribed. The possibilities (including potentially disturbing events) are endless.
BTW, would it even be illegal for an invested party to do this? Even if it is considered tampering, the blatant illegal shorting shows the big boys have no fear whatsoever, and wouldn't hesitate to pull a stunt like this.
