For those brothers who often trade contracts, little do you know that the transaction fees from frequent trading may even exceed your principal, which is a significant cost. 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 those who trade high-frequency contracts and large positions, your fee expenditures may exceed your principal in just a month. So, you must open a rebate; the fees you should get back must be reclaimed. If you don’t open for rebates, all fees go to the market. By opening a rebate, the fees are returned to your own account, saving you at least a few hundred to a thousand U in fees each month. If you have to spend, save what you can #Fee Rebate
