In the cryptocurrency market, "trading pairs" are the basic units of trading, referring to the exchange relationship between two assets. For example, BTC/USDT indicates trading Bitcoin (BTC) with Tether (USDT). The first asset is the "base currency," and the second is the "quote currency," with the price representing the value of one unit of the base currency.

Choosing the correct trading pair not only affects trading liquidity but also relates to conversion costs and potential arbitrage opportunities. Common trading pairs include ETH/BTC, SOL/USDT, etc., while some platforms also offer fiat currency trading pairs, such as BTC/USD.
