Recently, I've been thinking about the funding rate issue. The 24-hour average rate difference for a certain cryptocurrency is about -0.15%. It doesn't seem like much, but when you do the math carefully, it's quite interesting.

I tried opening a position with 200 USDT multiplied by 10x leverage for testing. The result was that in one day, nearly 70 USDT was earned just from funding fees. Converted to RMB, that's about 500 yuan a day, totaling 15,000 yuan a month. This number looks quite attractive at first glance—like finding a stable cash flow channel.

However, there are some details worth considering: the rate level fluctuates, and leveraged positions also carry risks. But if you can seize those time windows when the funding rate is unusually high, and manage your positions reasonably, this arbitrage idea can indeed generate significant profits. For experienced traders, this could be a good auxiliary income method.
