Ban's main force adopted the first way of playing. If the capital fee rate is changed to once every two hours, then the spot market will be quickly destroyed and the futures premium will quickly return. Collecting the capital fee twice should be enough to raise the premium again. These prices haven't fallen yet, and the contract position has started to drop a lot, which should be caused by the bearish action. My friends also asked me if it's worth buying at the bottom and if it will rise. I don't know, but I just want to say that Zhuang sold all the spot goods to the big smart ones. Who will pull the market? I don't know, so I won't copy the bottom.
