which makes me think mtgox got very lucky. I mean the hacker could overcome $1000 limit a day (roughly 80 bitcoins) by creating thousands of bogus accounts, putting on the market bid orders at $0.01 in all accounts, drive the market to the bottom like he did to fill his orders and quickly transfer 80 bitcoins from each account out of the exchange. he could get away with bitcoins worth of millions irreversibly and completely anonymously.
The 1000 USD is relative to the current price I suppose. So if I have access to an account with 500K bitcoins and I sell 400K bitcoins so that the price drops to 0.01 (like it did), and then I transfer the 100K bitcoin left in the account to my bitcoin address(and I can with the driven down exchange price) when the price goes back up I would have made a killing.
If you trust the Mt. Gox folks, they're now claiming that there was no server hack, just a database copy that some consultant had that got stolen.
If you trust what they're saying, which might be questionable since their business is pretty much going up in flames at the moment, so they are probably desperate to make things appear better than they are...
I hope for their sake that they actually have enough USD and BTC on hand to deal with the mass withdrawals that are coming...
