$ETH ETH, or Ethereum, is a digital currency and a blockchain platform. It is considered the second largest cryptocurrency, after Bitcoin. ETH is not only a currency, but also a platform where smart contracts and decentralized applications (dApps) can be created.

Why is Ethereum important?

* Smart contracts: These are sets of code that automatically execute when certain conditions are met. They are used to create many types of applications, such as digital currencies, supply chain management, and gaming.

* Decentralized applications (dApps): These are applications that run on a blockchain network and are not controlled by any central authority.

* Finance: Ethereum is a popular platform for DeFi (DeFi), or decentralized finance. It provides many of the services of traditional finance, such as loans, exchanges, and insurance, digitally.
