Currency pair is one of the basic concepts for trading on the crypto and other markets. The currency pair compares the value of one currency to another and indicates how much of the quoted currency is needed to purchase one unit of the base currency.
For example, BTC/USD is a currency pair that shows the price of BTC in terms of USD. In this case, Bitcoin is a base currency, while the US Dollar is a quoted one.
Currency pairs represent markets where one currency can be exchanged for another one. When you buy a currency pair, you buy the base currency and sell quoted one (for example, buy BTC for USD in BTC/USD pair). Conversely, when you sell a currency pair, you sell the base currency to get quoted currency (sell BTC to get USD in case of BTC/USD pair).
In the crypto market, there are two types of currency pairs — crypto-to-fiat and crypto-to-crypto. The first type means trading cryptocurrency against fiat currencies (ETH/USD). In the second type, cryptocurrency is quoted to another crypto (ETH/BTC).
