As far as I am, Satoshi Nakamoto is the person who invented bitcoin, but whether it's someone's name or Satoshi Nakamoto is the name of a team, all of that is still a mystery until now unsolved.
Satoshi Nakamoto is still unknown, anonymous, or a mystery, that is why many people claimed themselves that they are Satoshi, but no one believes them because they do not show any concrete evidence to prove that they are the real Satoshi. From my opinion, there is a possibility that Satoshi is a team since it is not very simple to create bitcoin and blockchain technology single-handedly, but if Satoshi is a single-person he is truly a genius.
