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?
Satoshi hid his identity because he needed to protect himself from outside threats, maybe some who liked bitcoin and some who didn't.
Especially now that bitcoin is very popular, of course many people who want to find out Satoshi's whereabouts then do things that are not supposed to. The main thing is his own safety.
