you can't redeem tether directly for USD from Tether
I've heard this for years, but the claimants never explain: How are all the exchanges staying afloat....I mean would exchanges keep purchasing Tether and can never redeem....how would those exchanges be getting USD to fund their operations.
Moreover, Tether is banked by Cantor. The ex-CEO is now Sec of Commerce, he has famously public said "Tether has the money"
