Trading pairs are essential in crypto and traditional markets, representing the value of one asset relative to another. In crypto, a trading pair like BTC/USDT means you can trade Bitcoin for Tether (a stablecoin). The first asset (BTC) is what you're buying or selling, and the second (USDT) is what you're using to make the trade.
There are two main types: crypto-to-fiat (e.g., ETH/USD) and crypto-to-crypto (e.g., ETH/BTC). Popular pairs tend to have higher liquidity, making trades faster and prices more stable. Less common pairs might offer opportunities but come with higher risk and volatility.
Understanding trading pairs helps you navigate markets efficiently. If you're holding a coin and want to buy another, you need to find a pair that supports the swap—or use an intermediary like USDT. Being aware of available trading pairs can help you plan trades smarter and avoid unnecessary conversions or fees.
