He is a shadow. He invented bitcoin and disappeared, so nobody knows what he is doing and where he is, but I heard he has some btc on his wallet
He may come one day, but no one knows when or if he comes forward, and none of his coins were spent, although the value of his possessions exceeds $ 600 million, so profits were not his motive. He could redeem these coins at any time, but decided not to. Probably, he will remain only a pseudonym of Satoshi Nakamoto, but this may change in the future. The creation of Satoshi Nakamoto still works and is supported by current developers.
