$RIVER has another terrifying point: the initial value of my position was only around 4500 USD, but after the increase, the value of the position rose to over 6000 USD. The fee calculation amount also changed from over 4000 USD to over 6000 USD. Assuming the price continues to rise, the value of my position will continue to expand. With the same fee rate, I will have to pay more funding fees, so really don't short, or just the funding fee alone can ruin a person.
