These triggers are stable altcoins and when created they are certainly backed up with a valid USD alias the correct USD.
But remember if the USD back is not correct then it is certain that the price of Tether will decline so sharply and this will have a negative effect on Tether.
So, to win the EThereum market at number 2, the better it is to create Tether quickly, but there must be another backup that is valid, aka not lying!
