#TradingPairs101 Trading pairs are combinations of two assets traded against each other on an exchange, forming the basis of transactions in cryptocurrency, forex, and stock markets. In crypto, pairs like BTC/USD or ETH/BTC allow traders to swap one cryptocurrency for another or for fiat currencies like USD or EUR. The first asset is the base currency, and the second is the quote currency, indicating how much of the quote currency is needed to buy one unit of the base. High-liquidity pairs, such as BTC/USDT, offer tighter spreads and stability, ideal for beginners. Understanding pairs is crucial for navigating markets, executing strategies like arbitrage, and managing fees effectively.
