I am curious to know which wallets belong to Satoshi Nakamoto? I heard that the BTC in them were never moved.
No real way to tell that Satoshi indeed owns wallets (unless he sends a signed message). You can assume which blocks he mined and therefore his wallets like so. http://bitslog.wordpress.com/2013/04/17/the-well-deserved-fortune-of-satoshi-nakamoto/
