I just wonder: are Early Adopters rich?
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?
It depends on at what time they have sold like if miners who were involved in bitcoin back in 2011 or so if sold at 2017 say around $19k they would definitely have been rich or if others still have the guts to hold till date knowing how much it will be used at these time.There are many people who just found their keys or wallet files at current time making them millionaires today so yes there are people who have been benefited from bitcoin a lot while some has loss also.
