$ETH

Ethereum ($ETH) is the second largest cryptocurrency after Bitcoin, launched by "Vitalik Buterin" in 2015. It is not just a currency, but a **decentralized platform** for running smart applications and smart contracts via blockchain technology.

It is distinguished by its support for revolutionary technologies such as:

- **Decentralized Finance (DeFi)**.

- **Non-Fungible Tokens (NFTs)**.

- **Transitioning to a "Proof of Stake" (PoS) system** in 2022, which reduced energy consumption by 99%.

Despite its technical superiority, it faces challenges such as:

- Sharp price volatility.

- Variable transaction fees ("gas").

- Competition from new blockchain chains.

It is a fundamental pillar in the future of web 3.0 and the digital economy.
