The golden rule of trading isn't complicated—let your winners breathe and eliminate your losers without hesitation. Set profit targets when positions work in your favor, but the real discipline comes from accepting small losses early. Holding onto underwater trades hoping for a reversal? That's how portfolios bleed. In volatile markets like crypto, position sizing and strict exit rules separate survivors from disaster stories. Take profits when technical levels align, cut losses when your thesis breaks. Simple math, difficult execution.
