Depends when really, there have been a few periods of time where buying/mining bitcoin turned out to be a pretty lucrative for anyone involved at the time. I mined some on my laptop about 15 years ago and ended up buying some steam games with it a few years later. Multiply that up to people who actually invested seriously, they made several times their investment.
NFTs? Basically all were scams and no one was ever going to make money apart from the scammer.
(Also nobody take this to mean BTC is a good investment today, if you're buying it today expecting exponential growth and not to potentially lose your investment entirely, you're being very silly)
I wonder if there are any investors in oil companies on Lemmy at all tbh
Like I've got a decent portfolio of investments, but I will never directly invest in oil (or military). Given the demographics here, I wonder if I'm a pretty typical investor or not
