USDT (Tether) is a stablecoin — a digital currency whose value is pegged to the US dollar: 1 USDT is always worth approximately 1 US dollar. This is maintained because the issuing company holds reserves (cash, US Treasury bonds, and other assets) equal to the amount of USDT in circulation. Unlike Bitcoin or Ethereum, whose prices can swing sharply up and down, USDT was specifically designed to stay stable — in Zorion you can use it just like regular dollars: hold it, send it, spend it, but faster and without being limited by banking hours.
