Now the phenomenon of malicious funding rates exceeding -1% is becoming more and more common. This is a typical malicious manipulation behavior to harvest retail investors, where a large amount of spot chips are concentrated in the hands of manipulators and platforms. Therefore, they can suddenly raise the spot price significantly. At this time, whether retail investors chase high to go long or short the contracts, they can only be harvested with no power to fight back. The platform is seriously derelict in its duties, not only failing to supervise but even colluding to participate in harvesting retail investors. Many retail investors have serious complaints but are helpless.
