When playing contracts with #返佣 , do not underestimate the transaction fees. This is a significant output, and novice players may not understand this and casually throw away money that rightfully belongs to them. High-frequency players even say that the fees might exceed your principal. Originally, the trade was profitable, but when you look at the account, it shows a loss—all due to your fees being drained away. For example, Binance charges a fee of 0.05% on market orders; if you open a position of 1000 U with 100x leverage, it would be 1000 * 100 * 0.001 = 100 U. If there’s no rebate, that 100 U is an unnecessary expense. With a rebate, you can earn back a portion of the funds, which can reduce your fee expenditure. If you make a profit, that money is pure profit. (You can check below to see if you have filled in the referral code)
