USDT, or Tether, is one of the first and most popular stablecoins, issued by Tether Limited. The main difference between USDT and traditional cryptocurrencies like Bitcoin or Ethereum lies in its peg to a real currency—the US dollar. This means that the value of one USDT is usually equivalent to one US dollar, making it more resistant to the volatility characteristic of other cryptocurrencies. The peg is maintained by backing each issued token with real US dollar reserves or equivalent assets. Unlike other cryptocurrencies, the USDT cryptocurrency provides stability and predictability due to its peg to the US dollar, making it ideal for use in international trade.
