If these walls really are his, he is the one getting trolled today. First wall got eaten, price rebounded, and now the next walls are getting munched
Why? He made a fuck load of money during this crash. And that's what his investors want -> FIAT!
BTC was down @ 455$, now above 700$ -> huge profits for people, that turned bear or had a good strategie.
Sell above 1000$ (he surely did), buy back between 455 and 550 (was easy with placed bids) -> sell above 700$
Wait for the next iteration. Even if he has to buy back @ 800$, he increased BTC holding much more than all bulls.
