Ethereum is a crypto-currency that appeared in 2013. Unlike Bitcoin, we know its creator: Vitalik Buterin. For those who don’t know, crypto-currencies are digital assets which can be used like Fiat currencies. You can use them to purchase goods (for example, from an Ethereum UK website), to make payments (for example, to an Ethereum casino), and for any other purposes: Basically, they are the digital equivalent of paper money. However, you cannot “hold” them in your hands.
