I thought the bitcoins have never been moved from satoshi's original wallet? Or maybe, if BiPolarBob is satoshi, he has an address that nobody knows about?
Coins from Satoshi's walet were moved atleast one time. I can't tell about that, it is plausible that he/she has an address but I think he/she spread the coins to a few addresses inatead of keeping it in one address..
