Hypothetically speaking, what if he just randomly died one day, yet no one knew, and everyone thinks he's alive still?
It wouldn't matter.
More on this matter, i watched bitcoin documentary and there was much very wise speculation who he was in one big circle of computer guys and he actually did die.
It don't affect bitcoin in any matter at all.
That really sounds good. I hope we can trust this "big circle of computer guys". I think this position is also very reasonable. What is the idea of creating the "currency of the future" if it cannot outlive you? Except of course you wish to live forever. Last I checked, this is impossible. So, basically no need for the scare. At least paper money outlive its inventors also.
