I agree that it is quite risky. States do not accept this currency not because the identity of the bitcoin Creator is hidden, but because they do not trust the technology. So I see no reason for the creator to reveal his secret.
I think, Bitcoin is an electronic money made in 2009 by Satoshi Nakamoto. The name is also associated with open source software that he designed, and also uses peer-to-peer networks without centralized storage or a single administrator where the US Treasury calls bitcoin a decentralized currency.
