What’s your biggest regret with crypto?

Aside from not buying in earlier, I had a sizeable amount of matic on Binance. It was locked in for 90 days which gave me around 15% APY. Matic reached its all time high, about 3 times its current value, and my friends were imploring me to sell the coins. No, I replied, as I’d accumulated around 200 matic coins by that point and if I cancelled the stake, I’d have to return the interest. “I don’t want to lose 200 coins!” Well here I am with my portfolio at 33% ish of its ATH. I missed out on tens of thousands of dollars but at least I got my 299 free coins, currently worth under $300
