I cannot believe you do not understand this: It is stupid to increase your slippage cost, reduce your execution chances and increase your counter-party exposure by selling only on one single exchange. It does not matter what followed after. And in his case, the price actually rose for months afterwards, and he sold at the bottom. Had he had a modicum of sense execution wise and technicals wise, he'd have done much better.

Also, I don't believe he has another 30k because the way he sold showed that he was in a rush, for whatever reason. I'm sure you agree.
