Contract trading fees have always been a significant expense.
Let me first teach you how to check how much fee you have already paid,

Binance's fee structure is 0.0005 for taker orders and 0.0002 for maker orders based on the nominal position.
Nominal position is the margin ✖️ leverage multiplier.
For example, with a Bitcoin contract of 1000u ✖️ 100x leverage, if there are two taker orders, then the fee for your order would be 100u, and if you place 3 orders in a day, that's 300u, which amounts to 9000u in fees for a month, and not to mention some traders who place far more than 3 orders a day. When you calculate it this way, you can see how terrifying it is; many people actually don't lose on trades but lose on fees.
So, it's very necessary to open a fee rebate for contracts; if you don't, the exchange takes it all. Once activated, a portion can be returned to you while you trade normally, which is like getting free u.
