While Ether (ETH) is often traded as a cryptocurrency, its primary purpose goes beyond being just digital money. Ether is the fuel that powers the Ethereum network. It compensates miners for securing the network, is used to purchase gas that powers smart contract execution, and is also needed for various operations within DApps. This dual nature - being both a tradable asset and a utility token for network operations - distinguishes Ether from many other digital currencies and underpins its integral role in the Ethereum ecosystem.
