When we talk about a cryptocurrency trading pair, we are referring to two digital assets that can be exchanged for each other on an exchange or trading platform. Pairs are written with their initials separated by a slash, such as BTC/USDT or BNB/BTC.

In the case of the $BNB/BTC pair, it means that you can buy or sell Binance Coin ($BNB) using Bitcoin (BTC) as the base currency or vice versa. This pair is especially useful for traders looking to diversify their portfolio within the crypto ecosystem without the need to convert to traditional currencies.

Similarly, the BNB/USDT pair allows you to exchange BNB with Tether (USDT), a stablecoin pegged to the value of the dollar. This facilitates fast and efficient transactions by trading with a stable reference.
