In my opinion, today no one will believe even the person who really says that he is the real developer of Bitcoin. Too much time has passed since that time, and today it is of no interest to anyone and will not bring much change. Since then, there have been so many rumors and various posts on this topic that the real truth is simply lost against this background.
I believe that behind this technology was a certain group of people, among whom was the main developer, and the technology itself was developed by certain structures, and in order to launch this technology, they spread a lot of rumors and secrets that hid the real truth. Where these people or this person is today, it is difficult to say. We only know the pseudonym, and anyone can hide behind it.
It's been a long time and probably will remain a legend, and may it, in the end, remain so.
