$USUAL contracts can indeed make money, but my lesson is—setting stops too tight. That time, my Ethereum long position was swept out at 2100, and the next day it shot up to 5000, I was so mad I almost bruised my leg. It seems like a small matter, but it actually reflects a big problem.

After the 1010 incident, I saw more clearly: not everyone is suitable for trading contracts. Especially for long positions, the risk is particularly high. Why? Because spot trading can be held indefinitely, but leverage and time costs in contracts can grind you down. Short positions, on the other hand, have an advantage—clear stop-loss points, controllable risk, and less psychological pressure.

This is not to say long positions can't be taken, but to admit: without sufficient capital reserves and mental preparation, trading contracts is like playing with fire. Many people watch the market rise and fall, but actually they are betting on whether they can stay calmer than the market maker—most people can't afford to lose this bet.
