Trading pairs are the foundation of any transaction conducted on cryptocurrency platforms. When you trade in the currency market, you are actually buying one currency and selling another. For example, when trading the BTC/USDT pair, you are buying Bitcoin and paying for it with the digital dollar USDT.
Trading pairs are used to measure the value of one currency against another and help in understanding the real-time performance of the currency. Choosing the right pair affects liquidity, fees, and even the speed of order execution.
