USDT, or Tether, is one of the most widely used stablecoins in the cryptocurrency market. Designed to maintain a 1:1 value peg with the U.S. dollar, USDT provides traders and investors with a stable digital asset that minimizes volatility while enabling seamless transactions across crypto platforms. Because of its reliability and widespread acceptance, USDT has become a cornerstone of digital asset trading—often serving as the primary trading pair for other cryptocurrencies like Bitcoin, Ethereum, and more.
For anyone entering the world of crypto trading, understanding how to buy and trade USDT is essential. This guide walks you through everything you need to know about USDT, including how to purchase it on leading exchanges like OKX, how to sell it for fiat currency, and best practices for secure transactions.
