$BNB BNB (Binance Coin) is a popular cryptocurrency used primarily on the Binance exchange. A BNB coin pair refers to a trading pair that includes BNB and another cryptocurrency, such as BNB/USDT, BNB/BTC, or BNB/ETH. These pairs allow traders to exchange BNB for other digital assets or stablecoins. BNB trading pairs are commonly used due to BNB's liquidity, low transaction fees, and integration across Binance services. BNB also powers Binance Smart Chain (BSC), enabling fast, low-cost DeFi transactions. By using BNB pairs, traders benefit from faster execution, discounted fees, and access to a wide range of trading opportunities.
