Who watches his addresses??? How will we know when if/when any are moved?
It's easy to know when they are moved, just look it up on blockchain.info or whatever blockchain browser of your choice. What's "funny" is, it seems the early addresses may be prone to quantum attacks (not post 2012 addresses) so even if some day the coins move, we will not know if someone made a successful quantum attack on satoshi's keys, or is satoshi him/her/itself moving coins.
Great observation.. this is huge because we can't be sure if it's him or not. The only way to know for certain is that he signs the transactions with his PGP, but at this point im not even sure if it's enough, because we can't know if it's him controlling the keys.
