I'm not sure, but there's a lot of people who are claiming that they're Satoshi Nakamoto. Who knows, Satoshi may be a man, a woman, or a group of people. But I have a feeling that this Satoshi Nakamoto is still alive and active in the crypto business esp. in running the bitcoin.

Another thing, there's no point for anyone to announce that they are the real Satoshi Nakamoto because it might put them in danger (security and privacy matters). Satoshi MIGHT be a billionaire now, so there's no point to publicize himself for popularity. He's already FAMOUS in the other sense.
