In virtual trading, trading pairs are a key concept, which are combinations of two cryptocurrencies used for trading. They are mainly divided into two categories: primary trading pairs, such as the common BTC/USDT, which are transactions between major cryptocurrencies and stablecoins; secondary trading pairs, like ETH/BTC, which are transactions between non-stablecoin cryptocurrencies. When selecting trading pairs, it is important to pay attention to liquidity, trading fees, and platform security, as these will affect the trading experience and profits, with Binance Exchange being the first choice.
