I think my son who tried to get me to buy bitcoing in 2012 may have cashed in on some as he's now in escrow on a $900k home. He makes a pretty decent salary though, but I'm not privy to current income. When he worked in LA he was making ~ $180k per year - but whatever his salary, I suspect ---> cha-ching, on bitcoin --- but again, don't know for sure.
I've mentioned this here before, but the reason we do not discuss it is two or three years back he said" "dad, the first rule of crypto: never tall anyone how much crypto you own". So I dont pry. He's married with 4 kids.
It's easier for rich man to go through the eye of needle than it is for a camel to get into heaven.
