When we talk about a cryptocurrency trading pair, we refer to two types of digital money that can be bought and sold against each other on an exchange or trading platform, such as Binance. It is most common to find these pairs written with their abbreviations next to each other and separated by a slash, like BTC/USD or ETH/MXN.

Following these examples, the BTC/USD pair means that you can buy or sell Bitcoin with US dollars (USD). Similarly, the ETH/MXN pair means that you can buy or sell Ethereum with MXN, or Mexican pesos.
