What is diff between USDT and USD?

USD stands for the United States Dollar, which is globally recognized as a reserve currency and widely used in international transactions. It is issued by the Federal Reserve System and serves as the official currency of the United States.

In contrast to USD, USDT represents Tether tokens, a type of blockchain-based cryptocurrency. Unlike other cryptocurrencies that are mined or issued through complex algorithms, Tether tokens are backed by an equivalent amount of traditional fiat currencies held in reserve.

The primary purpose of USDT is to provide a stable alternative to the volatile nature of many cryptocurrencies. By pegging its value to the US dollar, Tether aims to offer a more predictable and reliable store of value within the digital asset space.
