Why certainly? It would be quite remarkably dumb. In theory, a fiat-backed stablecoin is only supposed to be exposed to the fiat it is backed by.
Also: We just saw a supposedly reputable exchange blow up. These are the people who have lied enough to actually prompt US regulators to act: a hard bar to clear.
It's not "next level stupid" -- they will make billions. You could say (particularly with hindsight) that they could have made a fortune with a legitimate stable coin. But I don't think the economics would have worked for a legitimate stable coin to scale up fast enough to keep up with the scam ones.
I guess folks need to make their own decisions about whether being shy of sunlight suggests a need or a lack of need for disinfectant.
(Also, the original claim I was responding to was not that USDT is not backed by BTC or ETH, it was that USDT is backed by currency reserves. I don’t really know enough about these things to know if the goalpost needed to be in its original position, but I do feel obligated to point out that I see it moving.)
Well, except in the broader sense of crypto contagion. Tether is certainly exposed to BTC and ETH, both of which are plummeting this week.
