Caught some early momentum on a few altcoins and watched the position grow 2-3x pretty quickly. The target was within reach—60k+ on the table. But greed got in the way, and I didn't take the exit when the cards were right. Should've trimmed the bag when we were up massively, let the profits run on a smaller stack instead. Classic mistake of holding too long and watching gains evaporate. It's a hard lesson in conviction versus discipline. Sometimes knowing when to cash out is just as important as knowing which trades to take.
