I’d rather be repeatedly shaken before reaching the target position—even if it means stopping at break-even—than to be one of those “luzi” who just takes one knife, then another, then another. After doing this for years, I know the rule: you can wipe everything out with a single all-in loss. No matter how high the win rate is, if the risk-reward ratio is low, you won’t last long. Experts die from volatility.
