Can you also add fiat sum of deposits and withdrawals?
These have not been leaked as far as I know.
Unfortunately there is no proof...
About 300k btc was withdrawn in May after DHS seized the dwolla account. So everyone stared turning their fiat into btc and withdrawing. That's why there was a btc price premium on gox.
Ahh, how could I not think of that. Looks like it was the beginning of the end. So the DHS exposed MtGox' fractional reserve banking practice. LoL.
Still, in January when the spread between Bitstamp and Gox grew it almost looks as if some people knew more than others.
