this is Bitstamp cold storage address, which now reveal something interesting, these last transactions were made to refill the hot wallet so people who bought that 30K wall can withdraw their coins, but this is not the interesting thing, however there were only 148KBTC in that wallet a couple of weeks back, so this means the owner of the wall already had his coins at stamp all the time and he didn't send them there like some guys suggested here.

what is interesting, or rather annoying is that even after Gox people still leave their coins at exchanges...
