A friend of mine became insanely wealthy just off of Bitcoin. Immediately went off the grid a few years (back in 2017). Now owns a precious metals mining company in South America. Still holds Bitcoin, lives comfortably to a point, changed passports to evade sanctions (he was Russian), and even has a kind of his own private army, that's mostly involved in the mining business.

You wouldn't figure all of that out by simply looking at him, but strike him now and you'd have to contend against a few major governments at this point.
