If this is true:
From the 1814400 BTC awarded, 1148800 BTC has never been spent (63%) - should be the amount of BTC Satoshi mined.
THis is a decent amount of BTCs :)
On other hand, its still dangerous to have that many BTCs possible accessible by a single entity. Dont want to think about the price drop, if he would suddenly "recovered" his private keys :)
