#TradingPairs101 In cryptocurrency trading, a "trading pair" represents the exchange rate between two different assets. It's how you determine how much of one cryptocurrency you can get for another. For example, in the BTC/USDT pair, Bitcoin (BTC) is the base currency, and Tether (USDT) is the quote currency. This means the price you see reflects how many USDT you need to buy one BTC.
