We know AA, author of "Mastering Bitcoin" was once attacked because he did not made any fortune having BTC from early years, then people donated some BTC and he collected around 100BTC.
Hal F's wife sued "I am Satoshi guy" and they were talking about $ 3-digit mln, so they are not kind of people who wait every month for their wage.
What about others? Bitcoin Core developers? Forum admins or well-known old users? Are they crazy rich living in their own castles or did they lost their coins, sold for $10 because of mortgage loan or student's debt and today they must work 7-15 every day?
However there are many people that were interested in bitcoin back in the day that got no benefits out of it, and there are many reasons for that, they may have lost their coins long time ago, sold them for a low price, actually used their bitcoins to buy some stuff they needed or they simply gave up on bitcoin and did not believe it would reach the heights it has reached.
