The #TradingPairs101 (trading pairs) are the basis of any cryptocurrency exchange. They represent the value relationship between two assets, for example, BTC/USDT. The first currency (BTC) is the base, which is what you buy or sell. The second (USDT) is the quote currency, with which you conduct the transaction. Understanding these pairs allows you to exchange one crypto for another, monitor relative prices, and take advantage of market opportunities.
