i have been interested in shorting tether since 2017.

if i had gone through with it, i would have paid 5 years of interest for close to no return, including in 2018 when crypto fell 90%.

also, if enough people are levered short, crypto traders could short squeeze you. the price just needs to go up temporarily.

also, there's counterparty risk. is the exchange you're trading on going to stay up if tether goes to 0? depends on which one.
