Maybe I'm missing something obvious, but exchanges like Kraken actually offer margin trading on pairs such as USDT/USD and USDT/EUR. https://support.kraken.com/hc/en-us/articles/227876608-Margin-trading-pairs-and-their-maximum-leverage https://support.kraken.com/hc/en-us/articles/227876608-Margi... If somebody (probably a non-US-person who is allowed to do margin trading there) is convinced that Tether will tank, why can't they just go on such exchanges and initiate a short? Is the fear that the exchange itself will become insolvent after the crash, and you won't be able to withdraw your fiat out of it in the end?
