#TradingPairs101 In cryptocurrency, a trading pair consists of two digital assets that can be exchanged for each other. It's similar to traditional forex pairs (e.g., EUR/USD). The first cryptocurrency listed is the base currency, and the second is the quote currency. For example, in BTC/USDT, Bitcoin (BTC) is the base, and Tether (USDT) is the quote. When you see this pair, it indicates how much USDT you need to buy or sell one BTC.
