Well obviously no one knows... or very few people know (I still think that there are a couple original bitcoiners on this forum who are 99% sure that they know who Satoshi is).
Whats your favourite theory?
Mine is that it was John Nash

Please provide some proof for your theories. Would love to look into them!
Actually I don't think that it is really necessary to know. It's interesting of course but this uncertainty and mysticism give something special to crypto
It is enough that the creator of bitcoin is Satoshi Nakamoto. Even if we had him around, I dont think we would have rewarded him with Nobel Prize. However, the fact that is most interesting about the creator is that he holds one million bitcoin or at least this is what rumors says.
He must be a very rich person. But the guy deserves a big round of applause from the whole community of crypto coins. He has open the door to making money without going through ridiculous procedures.
