I think we would, my hunch is that he's definitely the kind of guy that would definitely show up and will show his presence
I am not sure how exactly you have come to this conclusion.
Satoshi has always tried to remain hidden. When Gavin went to the CIA, then Satoshi instantly stopped and sent
this email (tldr: I've moved on to other things.".
Satoshi sent this email on Apr 23, 2011.
Since then, we have no clue about his whereabouts. So, does he really give you the impression of a guy that would show up?
I don't think so too but thing about it this way, he's the richest man in the world and he can decide to probably flood the bitcoin market with those old bitcoins to literally shake the market but the problem is that, he's never going to be able to sell it all at once, would be difficult I think.
Let's say he does. Let's say he moves his coins and tries to sell them.
Where would he do that? In a CEX?
You know that the authorities will contact the CEX instantly and they will freeze the coins, until they are done with inspecting Satoshi (the real person).
