So there is some guy who built an entire empire around the globe with his vision to free the banking system and suddenly he appears out of now where to destroy it?
Not cool. He would not do that. He had purpose behind all these and he is richest man alive/dead on the earth with or without heritance of his property. I think there is no one who would just give that kinda money as free gift.
If he kept the secrete until now then he had his own reason. Feels like he has already bought secrete iceland somewhere safe and living his own life and drinking the pearls of nature!
I am not sure why someone like that will show up out of no where destroy that kinda beautiful life. It's money, he worked for this one, he won't let it go now. Who knows he is already funding the greatest missions of the world like mars travel, physics and scientific exploration etc. Why think in negative way about this guy anyway.

If Satoshi Nakamoto decides to show up then for sure it'll be in the headlines within that hour. The Founder himself/herself reveals his/her true identity will be on the news for several weeks. But I don't think that the founder will move that 1M because it will be such a huge mess or the system will crash, I think.

But I think NS will never reveal his/her identity for security purposes or maybe because the name Satoshi Nakamoto is a group behind the curtain.

Even if someone comes forward and reveals himself/herself as Satoshi Nakamoto, what'll be the deciding factor or believing factor that the respective person is Satoshi Nakamoto. Anymore the real identity isn't gonna get revealed. If he had the plan to reveal his identity, it could've happened years back. Now the market is mature and his identity isn't gonna make big disturbance in the market. Maybe if some disturbance happens, it'll not last long.
