Nah, it’s been good for the people who got in and out at the right times.
The issue with BTC is it has no underlying value and is little use as a currency so you’re just hoping more people decide to jump in and you can take profits and get out before everyone else. It might still go up in value and make some people very rich but it could easily tank overnight and leave the bagholders with nothing. There’s also zero regulation so some guy with a Twitter account can manipulate the market in ways that would be highly illegal in traditional security markets. Hence why it’s just a gamble.
Some crypto has some applications like smart contracts etc - BNB, VET, ETH - but I don’t think those will be as useful or as widely adopted as they are hyped.
I held some DOGE (the stupidest crypto) as a gamble and turned a $50 yolo into $130 or so and them dumped it all into VET. It was only as much as I was willing to lose if it went belly up and I’m under no illusion that it was just a punt, not a serious investment in something with actual underlying value.
