$ETH or Ethereum, is the second-largest cryptocurrency by market cap and a leading blockchain for smart contracts. Launched in 2015 by Vitalik Buterin, Ethereum revolutionized the crypto space with decentralized applications (dApps), DeFi, and NFTs. Unlike Bitcoin, Ethereum’s blockchain enables developers to build and deploy smart contracts, automating transactions without intermediaries. With Ethereum 2.0, the network transitioned to a proof-of-stake (PoS) model, improving scalability, security, and energy efficiency. $ETH is widely used for payments, staking, and powering Web3 innovations, making it essential in the crypto ecosystem. #Ethereum #Crypto #Blockchain #SmartContracts #DeFi
