The trading pair #交易对 represents a combination of two assets exchanging with each other in the financial markets and cryptocurrency space. For example, in the forex market, "USD/EUR" indicates that the former is the base currency and the latter is the quote currency, representing the amount of quote currency that can be exchanged for 1 unit of the base currency; on cryptocurrency trading platforms, "BTC/USDT" indicates the exchange relationship between Bitcoin and Tether. Through trading pairs, investors can conveniently conduct asset conversion, arbitrage, and risk hedging operations. Different trading pairs are influenced by factors such as supply and demand, economic data, and policies, resulting in varying price fluctuations. Investors need to closely monitor market dynamics and, in combination with their own risk preferences, make informed decisions on which trading pairs to invest in.
