Nothing is more funny to a bull than the OKcoin bear that got margin called today for 31,000 BTC/3 million dollars. His wife is gonna kill him.
No kidding, this guy was slaughtered on the alter of doom and it was a major shot across the bow of the bearmobile. If it can happen to this guy, it could happen to anyone. 
Very true. Too many people been getting fat for far too long just betting the fall will continue. Well a year and a half is a long time.
