the US dollar is also a scheme. I'm waiting now for more than 100 years to see it fall but it still doesn't happen. So this USDT is based on the same thin air?
They could hold the scheme up for so long because most of printed dollars are outside US borders. A likely scenario for a collapse of USD is when all the dollars come back to the US
Lot of dollars are in US companies that are in tax havens. All we need is a president that invites them in with a so called "tax holiday"... Oh, wait, it's already happening?
