USDT, or Tether, is the most widely used stablecoin in the cryptocurrency market. Unlike Bitcoin or Ethereum, which experience significant price volatility, USDT is designed to maintain a stable value pegged 1:1 to the US dollar. This means one USDT token should always be worth exactly one USD, making it a critical bridge between traditional finance and the crypto world.
For beginners entering the crypto space, understanding USDT is essential as it serves as a safe haven during market volatility and provides a familiar unit of account. This guide covers everything you need to know about USDT—from its basic concept to applications, benefits, and how to get started.
