Ethereum was not built to be a mere cryptocurrency. It is a hard fork created and it is meant to be a hub where developers can code, run, and execute DApps and smart contracts. How do you view the Ethereum?

Ethereum is King of smart contract platform, such as BSC, ADA , SOL and Matic.
They are crypto currency, not just.
