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 think everyone has the same regrets as like that you, especially Ethereum was the biggest regrets who sold it in 2017 when i bought more than 30 ETH but i didn’t hold for the long term and it was wrong decision but i sold it for urgent money. Whatever, even if i want to, i can't bring that time back. Yeah, not only ETH, so many projects we missed to hold tightly.
