Trading pairs are essential for operating in the crypto market. They indicate two currencies involved in a trade, such as PEPE/USDT or BTC/ETH. Understanding the pairs is important to know which crypto you are buying and with which you are paying. I usually trade mainly with pairs based on USDT, as it makes my profit calculations and portfolio management easier. With each move I make, I look at the volume of the pair and whether there is sufficient liquidity. For those who are starting, I recommend studying the most traded pairs and avoiding those with low liquidity.
