I mined over 250 ETH with a $2000 investment in video cards, when that still had a good ROI, and I purchased a few BTC when they were in the $400-$700 range. Got into bittrex and poloniex daytrading it, had my ups and downs, and then I consolidated everything I had left in 2017 when BTC hit $1000 and sold 15 and some change to pay off medical bills. (Which it just barely did, even after putting aside my cap gains taxes) Of course the whole thing has made me sick a few times since then. I had always said I'd hold out until they were $10k and sell half, and sell the other half when they hit $50k... but that's my luck. I did what I had to do. :)
Currently? I have 50 million or so SHIB because HEY... just in case. Holding out for $.01 (Like everybody else, I'm sure.)
It's money I would've blown in other useless ways. Not money I needed to get by. I always agreed with the 'never risk more than you can throw away' sentiment.
