Good overview of the stable coin class. I would add that Tether is super shady, they lie constantly and their connection to Bitfinex is also super shady. Watch CoffeZilla's expose on Tether and it's quite obvious they're a bunch of scammers. Unfortunately they're deep in the cryptoverse, so hopefully people stop using USDt and gradually their influence wanes. Their so called "backing" is total garbage, yet another of their lies. So stay away from holding USDt for any significant amount of time. Also USDt, USDC, and Paxos BUSD are highly centralized and can be frozen if the companies feel so inclined. This centralization of stable coins is a weakness in the crypto markets since they can be targeted by regulators especially in the good ole USA.
