I tried it once—went all-in on spots. It rose 20% and I didn't exit. Later it dropped back and I ended up losing. That's when I realized "can't hold" isn't a willpower issue; it's a position size problem.

Now my simple method: spot positions at most 70%, leaving the remaining 30% as a psychological buffer. Whether it goes up or down, I can sleep soundly. Futures? I directly set the liquidation price as my stop-loss. If it hits, it means I was wrong—I accept it.

Recently, more celebrity calls have appeared. Old group members keep saying not to catch the last train. Actually, the logic is the same—when your position is light, you can naturally wait for confirmation instead of panicking and cutting losses or chasing highs.
