PS in my opinion Tether doesn't have the fiat to back USDT like they say BUT they do hold a lot of crypto, which they are likely selling in mass right now to get the fiat needed to back their made up Tether tokens. IMO this mass crypto offloading is one of the major reasons for this recent crypto dip (dumping large amounts of their crypto holdings to get fiat to try to get themselves out of trouble... which may or may not work in the end).
