Interesting idea. On the topic of shorting Tether itself, 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-Margi 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? I'd be curious to hear thoughts on this.
