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.
long before bitcoin was as big as it is today, satoshi had thought about it, he was a living genius. if he/she reveals his/her identity then he/she will continue to be hunted by the government and even his/her family will be threatened, keeping his/her identity hidden is the best decision Satoshi has made to maintain the price of Bitcoin and also it existence.
