Each pair shows how much of the quote asset (the second asset) you need to buy one unit of the base asset (the first asset). Choosing the right trading pair involves considering liquidity, volatility, and your trading strategy. For example, trading pairs with stablecoins, such as BTC/USDT, are very good for reducing the volatility of fiat currencies, while crypto-crypto pairs can be used to diversify your portfolio in altcoins. Understanding pairs is very important for identifying market opportunities and building a balanced approach to trading.
