This coin has been in my hands for a while. Before logging into spot trading, the performance of the contract market was very interesting——regardless of how the market was shaken out or how it declined, the fee rate always remained high, which is a common phenomenon for many coins.

The trend yesterday left a deep impression: from 0.18 down to 0.16, then back to 0.18. This kind of wave pattern itself is nothing special. But the key turning point appeared——the fee rate suddenly flipped to a negative value. This signal is very worth paying attention to. When the fee rate reverses, it indicates that the market expectations have subtly changed, and the enthusiasm for shorting is decreasing. This is exactly the trading window that some institutions and veterans will watch closely. In the short term, this kind of fee rate reversal period often provides many operational ideas.
