I don't think so, but what do you think?
(Maybe I am naive, but is there any direct connections between Tether and Bitcoin?)
Tether is being used as a fractional reserve scam to prop up the price of bitcoin.
If tether collapses, then all of the fake money propping up bitcoin also collapses, causing a price drop to $400 or below.
(Price before Tether started manipulating the bitcoin price.)
At this price the miners will all go bankrupt, and the btc network will freeze.
