Many people will not thank you for making money, but will curse you when losing money. However, I always want to say, you should blame yourself more. Why do you always lose when you follow, while others make a profit? What is the reason?

When the contract has made enough profit, remember to run. The tactics of the market makers are too tricky; even a god cannot predict with 100% certainty what the next market move will be.

Spot trading is fine.
