#返佣 When trading contracts, one should not underestimate the transaction fees, as this can be a significant output. New players may not understand this and casually throw away money that should belong to them. High-frequency players even say that transaction fees can exceed your principal. Originally, the trade was profitable, but upon checking the account, it's all losses, all due to your fees being absorbed. For example, Binance charges a fee of 0.05%, based on you opening a position of 1000 USDT with 100x leverage, it would be 1000*100*0.001=100 USDT, and after rebates, you would receive 35 USDT back to your phone. Usually, living off these rebates is possible, so it's very necessary to open one.
