Aye, a friend of a mate who I know, is in the top 0.001% of Bitcoin investors mate. Wealthy doesn't even come close. Serial entrepreneur and a bit of an "I'm amazing" sort but still, happy to take his money in business and ignore the fact he spends most of the time higher the James Webb telescope. His favourite story is he once bought a pizza for 2 Bitcoin
He hasn't cashed all out because it wouldn't make any sense, he's just moved a lot around to cash and reinvested
