Almost every day a new person comes up with the claim that he/she is the real Satoshi. The real satoshi surely does not want any kind of fame. If he/she/they want fame he could have disclosed his identity earlier. But what could be the possible reason that Satoshi still hides his identity? Does he have a big plan for the future?
Anyone who said something about Satoshi's reason why he hides his identity is pretty much a guess. Satoshi never leaves any message about why he will be mysterious. Probably Satoshi is already dead (I hope he is not though) and had left all these unfinished and unpolished businesses/work regarding Bitcoins even before he decided to be known or reveal himself.
Mostly only conjecture because Satoshi also does not provide an explanation for this reason. if in my opinion maybe he prefers to be people behind the scenes, not visible but providing technology that has a big impact, but I am sure that he has a big reason to hide his identity
