I really can't hold onto my spot holdings; as soon as it rises, I want to lock in profits, and when it retraces, I get itchy to add more; futures are even worse, it's not that I see the wrong direction multiple times, it's that my position is too full, holding on and refusing to admit defeat, and finally it just blows up in my face.

Later, I tell myself a simple truth: don't think about finishing the entire story in one go, treat your position like a system patch, small fixes are enough, just stay alive first.
Only place bets that I can sleep peacefully with each time, if I lose, consider it rent, don't leverage to "recover losses."
Recently, the bridge was hacked again, and the oracle also had abnormal quotes, everyone is shouting "waiting for confirmation," I’ve also learned to be smart: better to miss a part than chase with emotion, keep your account healthy, revoke permissions, isolate wallets, and be more grounded.
