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.
I don't think Satoshi's identity would have an impact on Bitcoin's price at all unless that Satoshi would declare that he/she would sell the Bitcoin that he/she have.
I think the only impact that it would make is if there would be another crypto project that
"Satoshi" would make.
