A crypto trading pair consists of two different cryptocurrencies that can be traded against each other. It represents the value of one cryptocurrency in relation to another. For example, in the trading pair BTC/ETH, Bitcoin (BTC) is the base currency, and Ethereum (ETH) is the quote currency. This means that the price shows how much Ethereum is needed to buy one Bitcoin.Traders use these pairs to speculate on price movements, allowing them to buy one currency while selling another. This mechanism provides liquidity and enables market participants to exchange one cryptocurrency for another without needing to convert to fiat currency first.Crypto exchanges list various trading pairs, offering opportunities to trade numerous cryptocurrencies against each other. Understanding these pairs is crucial for making informed trading decisions, as different pairs can have different liquidity, volatility, and trading volumes.
