#TradingPairs101 Trading pairs are the foundation of the cryptocurrency market, allowing the exchange of one cryptocurrency for another, or cryptocurrency for fiat money. For example, BTC/USDT means that you are trading Bitcoin (BTC) against Tether (USDT). The first currency in the pair is the 'base' currency, and the second is the 'quoted' currency. The price indicates how much of the quoted currency is needed to purchase one unit of the base currency. Understanding trading pairs is critically important for effectively navigating exchanges, as they determine available exchanges and the liquidity of assets.
