Trading pairs refer to the assets that can be traded against each other in the markets, such as BTC/USD or ETH/USDT. In each pair, the first asset is known as the base asset, and the second is the quote asset by which the price is measured. Understanding trading pairs is essential to determining how to buy or sell assets. Some pairs are common and have high liquidity, making it easier to execute trades. Choosing the right pair affects trading costs and strategy. In the world of cryptocurrencies, currency pairs are one of the most important fundamental trading concepts. Knowing how to use them is a first step for any successful trader.
