I have been a futures call option teacher for three years. Whether it is futures or spot, it follows a law, that is, the law of 2:8. So what is the 2:8 law? For example, 10 people do futures, 8 people lose money, 2 people make money, or 2 people make money. If you are proficient in the operation of futures, you can be one of these two people. If you know nothing. Moreover, futures companies have to make money to maintain the normal operation of the company. What futures companies depend on to survive depends on these people who lose money. Therefore, futures cannot become their legitimate occupation.
