Hi, does anyone know how to explain this transfer of 2.2 million BTC (a third of all Bitcoins in existence) which happened the day of the Mt. Gox crash?

The only thing I can think of is that Mt. Gox moved their entire stash of customers' coins to a new account for safety in case their wallet.dat got stolen by the hacker...

Thanks for any insights,
-Mike
