What is crypto trading pair?
If we trade BTC for ETH, the trading pair will be BTC to ETH or BTC/ETH. Here, the first currency mentioned in the currency pair (BTC) is called the base currency, and the second currency (ETH) is called the quote currency. Since it is a pair, you can always buy one currency while selling another. In other words, a trading pair tell you how much of one cryptocurrency you can purchase with a given amount of a different cryptocurrency.
