Some coins are still profitable when I take my profit. When I look back and see that they are still rising, I shouldn't feel regret. What I have taken is mine. Since I have already sold, I shouldn't fantasize about this coin anymore. It can be compared to an ex-girlfriend; since we've broken up, there's no need to look back and torment myself. It doesn't matter whether it's good or bad, I should look forward!!! Looking for better projects.
