Here's my armchair two cents: Whoever it is, has to be British. The language is unmistakeably British or Commonwealth. It's likely him. I'd wager if there was a polymarket bet. But I also feel for him. Does this make him a target for both half-wit criminials and rogue nation states?

The British English could be a misdirection. Satoshi was always quite inconsistent, sometimes using US spellings ('color', 'check', 'optimize'). One that always stood out to me was his use of 'gotten' – we don't typically use that word in British English, but an American English speaker attempting to disguise themselves as a Brit most likely wouldn't be aware of that fact.

This is notable as it argues against a lot of the candidates who are American, but I would say this is relatively easy to fake if you were privacy minded.

It would be somewhat harder the other way (American pretending to be British) as American English is much more prominent, but I think I could convincingly pretend to be American in text if necessary if I was only participating in generally technical discussions (and nobody asked me about cultural stuff like NFL etc.)
