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?
Some early adopters became rich because they "hodled" Bitcoin no matter what. But others haven't been that lucky. I came into the Bitcoin scene in late 2014, but I'm not rich because I've spent most of my BTC in cloud mining companies and daily necessities. All of the cloud mining companies I've invested turned into a scam, so I was left with almost no Bitcoin in my wallet. It was a few years later that I've decided to invest my BTC into PoS coins in order to build a passive income system of my own. I'm now making a lot of money, but I'm still not rich, because again, I've been spending the profits on daily necessities.
To become rich is quite a hard task, especially when the crypto market is widely unpredictable. There's too much volatility where BTC can one day go up and then go all the way down the drain the other day. BTC is still below the projected $1m price per coin, so I'd still consider most of us early adopters. Just keep on "hodling" and maybe you'll get lucky someday.
