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.
Why 2020 why not 2010 when Bitcoin is just making headlines, we all have this kind of wish even Hodlers and long time investors
but even a coin have all the signs of a potential we still sell them for early profit not taking a chance to HODL longer it is because of the volatility of the market, coins are vulnerable to crash dumps and pumps it's hard to make a decision when you on this roller coaster ride.
There is no need to regret it, all coins which have proven themselves in the market can still go down and it's an open opportunity for us to take, and always look for a new coin to invest in with future potential in the market.
