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.
If you continue thinking this way that you sold your ETH cheap in 2020 because the price is higher now, you will always regret it in years to come because the price will surely go higher than it is in 2022. Instead of living in regret why not buy back whenever the price goes down. Do not mind that you will not get it at $120 any more. But still buy it. ETH can get to above $10,000 in time to come. If you miss it now you will regret more then.
