Trading pairs 101 is the foundation of trading on cryptocurrency and traditional exchanges. A trading pair shows which currency can be exchanged for another. For example, the pair BTC/USDT means that you can buy or sell Bitcoin for the stablecoin USDT. The first currency is the asset you are buying or selling (base), and the second is the currency in which the price is expressed (quoted). Understanding trading pairs helps to analyze the market, find profitable deals, and effectively manage a portfolio. This is a key skill for any trader, especially beginners.
