Is Ethereum a Token Version of Tether?

Users god tether as a balance for the us. D balance. Similar to how strike is working a in america and el salvador, when you send that us d balance to some one else, what is happening is the dollars are being sold for bitcoin instantly. And then on the receivers side, if the receivers a strike user, that bitcoin is then immediately being sold or us Dollars. If that's in el salvador or argentina, my understanding is then it gets converted into tether.
