#TradingPairs101 *Coin pairs* (or trading pairs) in cryptocurrency represent the two different cryptocurrencies that are being exchanged in a trade. When you trade crypto on an exchange like Binance, you're not just buying or selling one coin—you’re swapping it with another. A coin pair shows the value of one coin relative to another.

For example, the pair *BTC/USDT* means you're trading Bitcoin (BTC) against Tether (USDT), a stablecoin. If you buy this pair, you are using USDT to purchase BTC. If you sell, you're exchanging BTC to receive USDT. Another example is *ETH/BTC*, which allows you to trade Ethereum against Bitcoin.

Coin pairs are important because they help determine pricing and liquidity. Common base currencies in pairs include BTC, ETH, BNB, and USDT. The first coin in the pair is the *base currency*, and the second is the *quote currency*.

Trading pairs allow users to find the best routes for their trades. For example, if a direct pair doesn’t exist between two tokens, you might trade through a third coin like USDT.

Understanding how coin pairs work is essential for analyzing charts, placing orders, and maximizing trading opportunities in both spot and futures markets. It's a core concept in crypto trading strategy.
