I know a guy who stopped saying how many Bitcoins he had after he mined few thousands (by then Bitcoin was skyrocketing to single digit dollar values!) I know he kept mining for years.

I know for a fact he only sold 2 of those since then.

Now here's the interesting fact: he wasn't early into Bitcoin because of the technology, but because he was a full blown lunatic crypto anarchist. The guy literally works at some low paying job and has a normal life and lives dreaming about a world where Bitcoin's a common way to trade goods.

Seriously, he's easily worth hundreds of millions since years and he lives like a normal dude and spends his time just blogging and being a bitcoin evangelist.
