Have you used Tether.to to withdraw USD to a bank account? If so when?
I'm pretty sure you can't do that.
Here's some reassuring terms from here
https://tether.to/legal/"PURCHASE AND REDEMPTION OF TETHERS: The Site is an environment for the purchase and redemption of Tethers. Once you have Tethers, you can trade them, keep them, or use them to pay persons that will accept your Tethers. However, Tethers are not money and are not monetary instruments. They are also not stored value or currency. 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."
Would you entrust your money to something with those terms? It is however back to dollar parity.
Those terms probably aren't too far off the terms of many other more legit places, but 'more legit' is the key phrase.
