Yeah, I'm also curious if Satoshi Nakamoto is still alive, his whereabouts, his real name, his autobiography, and I guess, everybody is as curious as we are both. But based on what was written about Satoshi Nakamoto, it was just a pseudonym. It could be one person or a group, and his/their identity/ies was/were purposely hidden for some unknown reasons. I guess, it would be best for bitcoin if its proponent/s would be revealed, just like with ethereum. This would gain more confidence for the coin. But I'm pretty sure that he/they are still alive and he/they is/are watching and is/are just waiting for its baby bitcoin to finally go mainstream.
