$ETH The ETH coin pair, commonly traded as ETH/USDT or ETH/BTC, is a cornerstone of the cryptocurrency market. Ethereum (ETH) is the second-largest cryptocurrency by market capitalization and serves as the backbone for decentralized applications (dApps), smart contracts, and the broader decentralized finance (DeFi) ecosystem. ETH pairs are highly liquid and widely traded on major exchanges, making them a favorite among traders and investors. The ETH/USDT pair allows traders to speculate on Ethereum's price against the stablecoin Tether, while ETH/BTC measures Ethereum's value relative to Bitcoin. Ethereum's ongoing upgrades, such as the transition to Ethereum 2.0, and its role in NFTs and DeFi continue to drive demand for ETH pairs, offering both volatility and long-term growth potential.
