Open the Binance APP -- Funds -- Contracts -- Today's Profit and Loss -- Funding Fees and Trading Fees, and you can see your fees for the past year. For high-frequency contract trading and large position traders, your fee expenditure may exceed your principal in just one month.

Therefore, it is essential to open a rebate; the fees you should get back should be retrieved. If you do not open a rebate, all the fees go to the market. By opening a rebate, the fees are refunded to your own account, saving you at least hundreds to thousands of USDT in fees each month.
