the verdict of profit taking is very very dicey and you cant really blame yourself on it. what if price dumps after you sell. ? this is also part of it. its just a luck to sell at the top but its imminent we are satisfied with our profit. but when selling your tokens , always leave out some portion as moonbag for future sake.
I a gree with you. when I invest in one of the coins / tokens in the crypto market I feel comfortable when the coin / token I choose to pump, but when I dump I only have two choices, namely selling with a little profit or holding out at risk. I once sold a coin / token when it was dumped and after that the coin / token was pumped back and has a high price value. but it's okay I'm not angry because it's true that everything is luck.
