What Is a Crypto Trading Pair? How Do BTC/USDT Pairs Work?

Definition of a Crypto Trading Pair

1. A crypto trading pair represents a direct exchange relationship between two digital assets on an exchange platform.2. It consists of a base currency and a quote currency, where the base currency is the asset being bought or sold.3. The quote currency serves as the pricing unit — it determines how much of that asset is needed to acquire one unit of the base currency.4. BTC/USDT means Bitcoin is the base currency and Tether is the quote currency.5. This structure enables price discovery, order matching, and liquidity aggregation across decentralized and centralized venues.
