There are other stablecoins than Tether. And also, if you don't have any other options, what exactly you are selling USDT for? You must get something in exchange for it, not? So if you think that something is better, why didn't you use it at the first place? I could get it if it was a huge difference - USDT is at 0.50 or something - but if you sell at 0.995 then your preference for USDT was never that strong. For active money trader, it may make sense - if you manage billions, any tiny optimization in risk/reward can yield millions. But if we're talking about retail customer, it makes little sense.
