You'd better start assimilating new information before it's too late. There is a reason somebody would dump millions USD at 'below market'- he knows it won't sell at current prices. The whales don't believe in AM anymore and there was never 160M of value here.
Well, in this one transaction we're talking about 1000 * 2.7BTC or ~ $297,000 at today's prices. I'd say he's giving up about $100K by not waiting until the price bounces back, but time will tell if the millions get dumped, as you suggest they will.
