If I am given a chance to go back to 2020 I would hold my ETH very tight and never let go, when covid was hitting the world at its best I thought it over and I sold 24 ETH which I bought at 120$ each, I never knew I was so damn lucky to buy at that price, learn to hold tight if you believe in a project, there are countless of projects in past years that are way bigger in value right now.
I guess you sold out maybe because need money to help your self to solve problem, if that was the case then you had no choice than to sell. Cryptocurrency always have good opportunities for those who are ready to hodl, it is possible you can still get back thos opportunities you missed sometime ago agai . No late comer I'm Cryptocurrency, holding just the way.
