$ETH An Ethereum (ETH) coin pair is a trading pair on cryptocurrency exchanges where Ethereum is one of the assets, such as ETH/BTC, ETH/USDT, or ETH/USDC. These pairs allow users to exchange Ethereum for other cryptocurrencies or stablecoins. Ethereum, as the second-largest cryptocurrency by market capitalization, is widely traded and offers high liquidity. It is favored for its role in decentralized finance (DeFi), non-fungible tokens (NFTs), and smart contract platforms. ETH pairs provide traders with opportunities for diversification, arbitrage, and access to the broader crypto ecosystem, making them a core component of most cryptocurrency markets.
