There is a big flaw in your uncles logic.
When I get this right, he thinks, that satan is working in the shadows, that's why Satoshis identity will never be revealed.
But bitcoin is as open as anything could be. How does that mix?
No he just said satan(satoshi in this case) would not reveal himself! I think the open nature of blockchain need not be confused with this
I still don't see how that mix. How does Satan profit from something, nobody can control?
