How does OKEX borrow/Repay work in the context of USDT? I am unable to borrow USDT to leverage long my positions. Support have told me that this is because there is no more left to borrow? I'm very surprised by this, but is there anyway to profit from this? I.e. Can I loan my USDT at a high rate? Additionally - is this a common occurence? Is there some way to monitor the available borrow amounts?
