This title should be updated to “patio11 thinks Tether is on the early stages of a bank run”. The title implies fact, but this is just one persons tweet.
As far as I know, there's no way to actually redeem your USDT from Tether itself. How can you have a bank run on a "bank" that doesn't offer withdrawals?
Can buy BTC on Bitfinex and sell on a real USD exchange. Explaining the premium.
The question is, can the people behind tether buy enough of it at high enough price to bring back price to 1$
