#TradingPairs101 The trading pairs are the basis of any operation in an exchange. For example, in the pair BTC/USDT you are buying or selling BTC using USDT. There are crypto to crypto pairs, like ETH/BTC, and crypto to fiat or stablecoin pairs, like SOL/USDT. Choosing the right pair depends on your strategy: if you are looking for stability, opt for pairs with stablecoins; if you are looking to take advantage of market movements, you can trade between altcoins. In addition, pairs with higher volume usually have lower spread and greater liquidity. Understanding how pairs work will allow you to make smarter decisions.
