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?
The main thing is that if he would have shown his identity to the world then bitcoin would have become centralized as he would bear the responsibility of everything and also government could also find a way to defame him. But since bitcoin is not having a father so it have become community driven currency and the decisions are made by the people on what to do and the future of bitcoin.
It might be the one his reason, also, maybe he really wanted his creation to be known rather than him and it will be his greatest achievement, we don't know what's on his mind but for sure he's genius enough to realize all of this things, or maybe he's already dead just like what others are saying, just hoping that before the end of the year 2020 we will finally know who's the real Satoshi.
