#TradingPairs101 A trading pair in crypto represents two different currencies you can trade between — like BTC/USDT or ETH/BTC. The first currency is the base, and the second is the quote. If you trade BTC/USDT, you're buying Bitcoin using Tether or selling Bitcoin for Tether. Choosing the right trading pair can impact your trading strategy, fees, and potential profit. Popular pairs usually have higher liquidity and lower spreads. Knowing how trading pairs work helps you navigate the market more efficiently and diversify your portfolio across stablecoins, altcoins, and major cryptos.
