As a cryptocurrency, Ethereum’s Ether (or ETH) can be exchanged for other cryptocurrencies or converted to traditional fiat currencies (cash) via brokerages. But increasingly businesses are allowing direct conversion of Ether to products or services. We expect the number of firms allowing this to grow. Here is a list of 70 firms that accept Ethereum.
Ether can be traded with anyone who has a Ether wallet address. Ethereum is very good at facilitating peer-to-peer transactions, and it is cheaper and faster than the Bitcoin.
Since Ethereum enables Smart Contracts there can be transactions that are only executed once criteria are met. So transactions do not need the involvement of a third party or escrow service or bank.
