Can that big shot tell me how to calculate this? I have 7000 yuan and opened a contract, choosing 75x, so the capital should be multiplied by 75 times. I used 50% of the capital to open the position, so shouldn't the remaining 50% principal also be 3500? If 3500 makes a profit of 7%, shouldn't that be over 200 yuan? Why is mine only a dozen yuan? Not to mention the 75 times? Am I opening a fake contract? $BNB
