$ETH Ethereum ($ETH) is the second-largest cryptocurrency by market capitalization after Bitcoin. It’s more than just a digital currency—it’s a decentralized platform that enables developers to build and deploy smart contracts and decentralized applications (dApps). Ethereum introduced the concept of programmable blockchain, allowing developers to create custom tokens, DeFi protocols, NFT platforms, and more.

Unlike Bitcoin, which mainly focuses on peer-to-peer transactions, Ethereum is like a global computer that runs on blockchain. With the upcoming updates (like Ethereum 2.0), it continues to evolve towards being more scalable, secure, and energy-efficient by shifting from Proof-of-Work (PoW) to Proof-of-Stake (PoS).
