$ETH Ethereum (ETH) is one of the most popular and important cryptocurrencies today. It’s not just digital money like Bitcoin. Ethereum is a whole platform where people can build apps that don’t need a central company or control. These are called decentralized applications, or dApps.

Ethereum also uses smart contracts—digital agreements that run automatically when certain conditions are met. This makes things like trading, lending, and games more secure and open.

Recently, Ethereum changed the way it works. It moved from Proof of Work to Proof of Stake, which uses less energy and is better for the environment. It also helps make Ethereum faster and more secure.

Many new projects, like NFTs and DeFi apps, are built on Ethereum. That’s why it’s still one of the top choices in the crypto world.
