Believe it or not I bought my first bitcoins in 2011. I bought 2500 bitcoins at just over $2 a piece. Unfortunately, I sold most of those when they hit $5. It was a tidy profit of about 7k in a month and I couldn't have been happier at the time. The rest I lost in the mtgox meltdown. Since then I've bought and used btc to pay for everyday purchases. For a while I had a credit card that I could use at the grocery store and it would pull btc from my coinbase account. In 2017 I invested in a bitcoin mining firm and still own shares in that. It's been a good investment but not as good as if I'd just bought bitcoins.
The best money I ever made in crypto was in 2017 arbitraging between different exchanges. I remember a time when litecoin was selling for 20% more on coinbase vs poloniex. All you had to do was buy it at poloniex, send it to coinbase, and sell it. Repeat, repeat, repeat.
I don't currently own any crypto. But having shares in a btc mining firm is pretty much the same as holding btc.
I sold whatever bitcoin I had in early 2021 at the 36k mark.
