Ethereum P&L: 0 ħ (≃ 0 EUR)

Ethereum is a project to create a Turing-Complete decentralized open source blockchain. It is a community project of primarily developers, and miners and exchange managers, developed primarily by developers and run by largely anonymous miners, who freely and arbitrarily decide to contribute computing resources for the benefit of the cryptocurrency mined (e.g., market value), that is created by exchanges (run by people as other projects) that approve of listing it or its sub-currencies (programs within it) as traded assets, because of easy common class interfaces, like ERC-20 or ERC-721.
