I guess your proof is that giant green candle that just happened.  "They" were trying to shake out as many longs as possible by crashing the market as low as it would go.  The part that confuses me is that it seems like he would lose a good amount of money himself by shorting that hard when it was already at the bottom and having to cover that large amount of coins.  That is, unless "they" plan to take this thing straight up into the stratosphere so high that it would be worth it to get rid of longs early.
