I hate to point out the obvious here, but it no longer makes sense for Ken to sell machines when Bitcoin is almost $600. He would make far more profit mining with them himself. Not like we would see any of the mined profits anyway, he will find a way to keep them for himself.
Well, since there is a publicly documented statement regarding dividends, if he does that there will be repercussions.
Though I don't think that will be the case.
