#TradingPairs101 TradingPairs101 introduces the concept of trading pairs, which represent the two assets being exchanged in a trade, such as BTC/USDT or ETH/BTC. The first asset is the **base currency**, and the second is the **quote currency**. A pair shows how much of the quote currency is needed to buy one unit of the base currency. Trading pairs are essential for navigating both centralized and decentralized exchanges, enabling users to move between cryptocurrencies or between crypto and fiat. Understanding trading pairs helps traders identify arbitrage opportunities, measure value changes, and select the most efficient route for exchanging their assets.
