A virtual currency named ether grew alongside bitcoin. Ether is the fuel that powers Ethereum. Bitcoin and Ethereum are at times considered to be similar but that's not entirely true, as bitcoin is a cryptocurrency, whereas Ethereum is a development platform. Ethereum is considered to be the largest and the most well-established, open-ended decentralized software platform. Ether is like a vehicle for moving around on the Ethereum platform and is sought by developers to develop and run application inside Ethereum.
