Well, it's a good thing they don't have anything like this in their Terms:
> "There is no contractual right or other right or legal claim against us to redeem or exchange your Tethers for money. We do not guarantee any right of redemption or exchange of Tethers by us for money. There is no guarantee against losses when you buy, trade, sell, or redeem Tethers."
Oh, wait, that's exactly what is in their Terms...
