I think everyone in crypto makes more or less mistakes. I myself have regretted many wrong decisions in the past. I got a token at the beginning of my crypto journey in 2118, I sold it for only $45, that token reached $4500 in a week's time. Recently I had several PBR, DOT, SOL, ADA, PLOOZ tokens. After selling them, the price of each token increased several hundred times. Now I am trying to learn from these mistakes and move forward.
