$ETH An ETH pair refers to a trading pair on a cryptocurrency exchange where Ethereum (ETH) is one of the assets. For example, in the ETH/BTC pair, traders can exchange Ethereum for Bitcoin and vice versa. ETH pairs are commonly used in crypto trading to determine the value of other cryptocurrencies relative to Ethereum. These pairs are important for price discovery and liquidity, especially on decentralized exchanges (DEXs). Traders use ETH pairs to take advantage of price fluctuations, diversify portfolios, or move assets between blockchains. ETH is often used as a base currency due to its widespread adoption and strong market presence.
