#TradingPairs101 When you trade on Binance, you’re not just buying or selling a coin—you’re interacting with a trading pair. A trading pair shows what two assets you’re exchanging. For example, in BTC/USDT, you’re buying Bitcoin with Tether or selling Bitcoin to receive Tether. The first asset (BTC) is the base, and the second (USDT) is the quote currency. Understanding trading pairs helps you track price movement, choose the right market, and plan your entries or exits. Always double-check the pair before trading—mistakes can be costly. Whether you’re spot trading or using futures, know your pair before you place your order.
