Actually all the coin was dump to the bottom.UST price was going down then the expected one.Because the price of all the crypto currency was reduced,but I don’t know why the topic was started only for the UST.The price of coin which was increased is only the USDT.Because the buying of new crypto currency by the investors was happening only with the USDT.USDT only had huge demand for now.
