Here's the question nobody's been asking:
What happens to the thousands of bitcoins the hacker withdrew from Mt. Gox? Mt. Gox can't print Bitcoins like the Fed prints dollars -- BTC are hard as heck to produce.
.... wow.
He didnt withdraw them. He tried to withdraw money, but mtgox has a hard cap of $1000 dollars.
MtGox got closed soon after.
The hacker had access to everyone's passwords. The hacker crashed the market to $0.01/BTC. Mt Gox allows withdrawls of up to $1k or equivalent in BTC. Someone moved 500k BTC soon after crashing the market. Put all those together.
