Mr. Satoshi is really a genius in hidding.
Still today no one could find his identity, nor even the national agencies could make it.
Question:
Besides Tor and PGP, what technologies else did Satoshi use to protect his anonymity?
Nick Szabo showed himself to be Satoshi Nakamoto when he back-dated the notorious blog post about digital currencies after Bitcoin was released and then disappeared for the next 2 years only to reappear shortly after Satoshi vanished.
