#TradingPairs101 A trading pair shows how one cryptocurrency is exchanged for another, like BTC/USDT. The first asset (BTC) is what you're buying or selling; the second (USDT) is what you’re using to buy or measure value. Popular pairs have more liquidity and lower spreads. If you're trading altcoins, you'll often go through a base like BTC, ETH, or USDT. Understanding pairs helps you choose efficient trades and manage risks better. Always check the pair’s volume and volatility before trading.
