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

Therefore, you must enable commission returns; the fees you should get back must be claimed. If you don't enable the fees, they all go to the market. By enabling commission returns, the fees are refunded to your own account, saving you at least a few hundred to a thousand U in fees per month.
