As far as Wind_fury being rich, let's say on his btctalk Date Registered: May 21, 2016
Price of BTC was ~$7000 per coin.

If you're trying to analyze something, at least get your facts right.
I don't know where you're taking your information but the bitcoin wasn't even close to $7000 at the time.
If anyone invested $2,000 in bitcoin in 2016, he could cash out over $200,000 now. That's not bad at all for a five-year period.
