Trading pairs allow you to exchange one asset for another, such as BTC/ETH or ETH/USDT. Each pair shows how much of the quoted asset (the second asset) is needed to purchase one unit of the base asset (the first asset). Choosing the right trading pair involves considering liquidity, volatility, and your trading strategy. For example, stablecoin pairs like BTC/USDT are great for minimizing fiat volatility, while crypto-to-crypto pairs can be used to diversify your portfolio in altcoins. Understanding pairs is crucial for identifying market opportunities and building a balanced trading approach.
