Transaction fees are an expense that must be considered during the trading process. You may not realize it until you look, and then it's shocking. A single transaction fee of eight U can cost you dozens of yuan, so frequent trading must take into account the erosion from fees. You might feel like you're making money, but when you take a closer look, the overall loss becomes apparent, all due to fees. Because with high leverage, the fees are not based on how much you actually invest. They are based on how much you are using; if you use one hundred times leverage, you will be charged fees based on one hundred times the capital. When you play with high leverage, it all turns into fees, and real money is gone. $BTC
