Still kicking myself for bailing on that memecoin too early. You know that feeling—you catch a small move, take the profit, then watch it pump another 10x while you're sitting on the sidelines. Hindsight's brutal in crypto. The worst part isn't even the missed gains, it's that nagging question of whether you made the right call or just got lucky with your timing. Anyway, these are the trades that teach you the most, I guess.
