I've been wondering, what's the downside with Tether shorts? If it remains stable, then the shorts don't move in value. USDT is unlikely to moon above $1.00. If it collapses then the shorts print money. All you pay is the fees associated with creating and maintaining the positions. Seems like it's all upside.
I'm assuming there's some counterparty risk with exchanges blocking trading of synthetic derivatives if the underlying asset is imploding?
