I think satoshi should popup and accept Nobel prize
How would we know it's really him and not an impostor?
I agree with that. How do you prove hes "real" Satoshi especially if he is dead. Also what happens if Satoshi is group consists of a couple of people? Some maybe want to take it and some dont want to disclose their identity and risk their life.
Anyway, I dont think he/they will show up to take the Nobel if he/they deserve it.
Ummm, his PGP key is still known.....
