On kraken, one can short Tether against the US Dollar. Since Tether is usually pretty close to $1, I wonder if it’s worth it to open a short in case it’s all falling apart. I mean, in case of a crash the price of tether would most certainly fall, right?
If Tether controls the price of Tether, they can simply cause Tether to spike to $2 or $10 for a few days or weeks, before leaving. Tether may drop below $1 afterwards, but you might get short-squeezed on the way out.
There's no way you can win vs an entity that fully controls the price.
