The #交易对 trading pair is a trading combination in digital currency trading, consisting of two different digital currencies or one digital currency paired with one fiat currency, used to represent two assets that can be exchanged for each other. For example, on the Binance exchange, BTC/USDT is a common trading pair, representing the exchange relationship between Bitcoin (BTC) and Tether (USDT). Traders can use this trading pair to buy BTC with USDT or sell BTC to exchange for USDT.

Here are some common types of trading pairs:

• Mainstream currency trading pairs: Such as BTC/USD, ETH/USD, etc., consisting of mainstream digital currencies like Bitcoin and Ethereum with fiat currencies like the US dollar, these pairs are relatively active and closely watched.

• Stablecoin trading pairs: Like USDC/BTC, DAI/ETH, etc., combinations of stablecoins with other digital currencies. Due to the relatively stable value of stablecoins, they are often used for hedging or as an intermediary medium for trading.

• Altcoin trading pairs: For example, LTC/BTC, XRP/ETH, etc., are trading pairs between other digital currencies outside of mainstream currencies. The price fluctuations of these trading pairs are usually larger and have higher speculation.
