#TradingPairs101 A trading pair in crypto shows which two currencies are being exchanged. For example, in the BTC/USDT pair, you're trading Bitcoin for Tether. Choosing the right trading pair can affect fees, liquidity, and even your profit potential. Major pairs like BTC/USDT or ETH/BUSD have higher liquidity and tighter spreads. Lesser-known altcoin pairs may offer big gains but come with higher risk. Always check volume and market depth before executing a trade. Understanding trading pairs is key to navigating the crypto market efficiently.
