Tether (USDT) is a type of cryptocurrency known as a stablecoin, which aims to keep cryptocurrency valuations stable. Tether is pegged to traditional fiat currencies like the US dollar and the Euro, with the company claiming that it is backed by equivalent fiat currency reserves. This connection is supposed to result in a more stable digital currency, less prone to the intense volatility common in other cryptocurrencies. This stability makes Tether a popular choice among crypto investors, especially in countries like Germany where people seek efficiency and security in financial transactions.
