A friend of mine lost more than 800,000 yuan in this wave of decline. Now he feels most sorry for his family. I want to give a piece of advice to all the leeks who have just started or even played for a while: Don't play contracts if you can, and don't touch leverage. Contracts are about human nature, and few people can control their desires. If the principal is small and the leverage is high, it can't withstand the fluctuations and will be lost. The probability and mentality will lead to losses if you gamble for a long time. When you win, your mentality is easy to drift, and when you lose, your mentality is easy to panic. It is almost as addictive as gambling, and it is more violent than gambling.
