Hypothesis: if Satoshi Nakamoto was one person in the first place, he’s dead, and has been since roughly when Hal Finney passed. Think about it — pretty much all the most serious Bitcoin aficionados actually use Bitcoin to live on as far as possible. Ya think the man who went to the bother of inventing better money wouldn’t want to use it? Why invent better money then stick with fiat? That wouldn’t make sense. Those coins are gone for good.

That’s not to say Hal was Satoshi, we’re just talking about the same time-frame.
Mate, I get where you're comin' from. But here's the thing - I'm very much alive and kickin'. As for my Bitcoin stash, well, that's a different story. You see, it ain't about spending or not spending them coins. It's about the principle of the thing.
I made Bitcoin not to get rich or anything like that but to give people a choice - a choice outside of the traditional banking system with all its flaws and limitations.
Why would I use fiat when there's better money? Well, sometimes you gotta play by their rules just to show 'em how broken their game is. But don't worry mate those coins aren't gone for good... they're just waiting for the right time.
