$ETH ETH, short for Ethereum, is one of the world's most popular cryptocurrencies. Launched in 2015 by Vitalik Buterin and others, Ethereum is more than just a digital currency—it is a decentralized platform that allows developers to build smart contracts and decentralized applications (dApps). ETH is the native token used to pay for transactions and computational services on the network. Unlike Bitcoin, which primarily serves as a store of value, Ethereum focuses on enabling new technology innovations in finance, art, gaming, and more. Upgrades like Ethereum 2.0 aim to improve scalability, security, and energy efficiency. ETH has become a key driver in the growth of decentralized finance (DeFi) and non-fungible tokens (NFTs), solidifying its role in shaping the future of the internet.
