The handling fee is the most intuitive way to save money directly in hand. Just talking about it doesn't feel real; let's do the math: Taking 1000U as an example: The contract trading fee rate on Binance is 0.05%. If I open a position with 1000U at 100x leverage, the trading fee for one transaction would be 1000 * 100 * 0.05% = 50U, meaning that 100U is lost just in opening and closing the position once. Those who have traded contracts know that it's quite normal to open positions several times a day. Let’s calculate based on opening and closing positions 3 times a day; over a month, the handling fees alone would amount to nearly 10,000U. If you trade contracts long-term, opening positions of 1000U each time, the total handling fees for a year would be 108,000U, equivalent to around 800,000 RMB. We also welcome everyone to recommend this to friends around you, especially those who frequently trade contracts; it’s very necessary. If you're trading high-frequency with large positions, you could save enough for a SU7 in a year.
