How many people can really make money playing contracts? Everyone should reflect on themselves. This kind of thing is only suitable for small play. If you spend all day gambling inside, betting on dozens of positions in a day, and if you get one direction wrong, 95% of people will choose to hold their positions. When a one-sided market comes, you will end up being liquidated, especially if you open 10% positions with 100x leverage. I really admire such people. You are not a fortune teller; you can't predict that every trade will be correct. Not everyone is a crypto expert, so this kind of thing is just for small play. If you gamble all day, you might as well work honestly.
