One of the reason for high trust on bitcoin is that the bitcoin owner Satoshi identity is hidden. If all of sudden Satoshi come in the public and his identity is revealed, do you think it will have a bad impact on the bitcoin price and it can dump? Or do you think that bitcoin price will pump on this revelation? Mind you that i am talking about the real satoshi, not the fake ones claiming themselves to be satoshi.
Satoshi gave the code away to public. He is not controlling the code base or it is not closed source.
What difference would it make if he shows up to a party?
PS: What if he is actually a Washington insider a closet politician / coder?
