You'd better not play with contracts anymore.

I want to know if the Binance contract model is fair. First, my return on investment is 200%, my initial margin is 500, normally I should profit over 1000. Third, my return on investment is -400%, my initial margin is 1000, normally my loss is over 4000. The current issue is that when I profit, they reduce my margin, resulting in only a few hundred in profit, while when I lose, they increase my margin, causing my losses to reach over 6000. So the conclusion is that if I profit, I will only win less and less, while if I lose, I will lose more and more! This is unfair
