The banking system is behind most of the cryptocurrencies. They want to familiarize us with crypto, it is the first step to make us accept the CBDCs, which was always the plan. I already hear many crypto libertarians saying: "I use USDT because it's more convenient, the value is stable" 
You really think banks are behind crypto? If they were behind crypto, they wouldn't had been against it in the first place. Their response of launching CBDCs of their own, tells us they're afraid Bitcoin will take over the mainstream economy. If they don't do the move, people will simply abandon Fiat for Bitcoin. With the introduction of CBDCs like the Digital Dollar and the Digital Euro, banks will be able to stay in power for a little while.
In fact, CBDCs will give banks and governments more power than usual as they will be able to have a full scope of people's finances. Every transaction will be visible on a digital ledger only they can control. They can't do that with traditional paper money, though. For the end user, the Digital Dollar would work almost exactly the same as credit/debit cards. The person won't notice any difference at all (except banks). Bitcoin's been going strong since day one, so it's likely it'll live alongside the US Digital Dollar for generations. Just my thoughts
