To be honest, it's not really our business whether they got rich or not by being an early adopter, but if it makes you sleep in peace OP, I believe that all of them are rich but they don't want you or anyone to know it so they live by their means or they slowly stream in the wealth to gradually live a luxurious life. It's crazy to think that early adopters wouldn't make money because by logic, they should have a lot of crypto since it's the cheapest.
Not all, remember the pizza guy? That is just the most known one, there are a million people like that, including myself, I may have not been here when it was just a few dollars or even cents, but I have been here since it was under 100 dollars and I can tell you that I never got rich, I am still working very hard for my salary every single day.
I am not upset about it neither weirdly enough, because without crypto my life would have been terrible and I feel like it could still yet be terrible any day now and keep being scared about it. So I can easily say that we are not all rich, but we are still happy to meet bitcoin no matter what our current finances look like.
