Good points,can't get disagreed. Everyone has their own portfolios, they add crypto-currencies there, after hardly analysis according to them but sometimes when market goes down, people dumped their coin, without any re-analysis as if it is the end of crypto world bt after bounce back, they start regrating about what they did. Even i also dumped so many top coins like btc soL bnb but now we can see, how successful project those are!
Yes, for some reason it is easier for people to sell coins than to choose and invest in them. When you sell, some kind of instinct triggers that turns off the brain. I also do this when I have a panic mood due to a drop in the price of some coin in my wallet. Despite this, I try to keep my nerves in my hands and this allows me to avoid unnecessary emotional and material costs.
