Ethereum ($ETH), the second-largest cryptocurrency by market cap, plays a vital role in the digital asset ecosystem—especially when it comes to trading pairs. The $ETH pair is commonly used across top exchanges, offering liquidity and flexibility for a wide range of altcoin trades. Unlike Bitcoin, Ethereum's value isn't just driven by scarcity, but also by its powerful utility—supporting smart contracts, DeFi platforms, NFTs, and more. As Ethereum continues to evolve, particularly with its shift to proof-of-stake and upcoming scalability upgrades, its trading pairs are becoming even more influential. Monitoring $ETH pairs can provide valuable insights into altcoin strength, Ethereum network activity, and broader market trends. Traders often use ETH as a base pair to diversify their portfolios, especially during times of BTC volatility. Whether you're holding or actively trading, $ETH remains a cornerstone of the crypto market.
