Ethereum will surely bloom this 2018. A lot of tokens (ERC-20) uses ETH mainnet / blockchain. This helps ethereum to increase its market since they need ETH to trade, because ETH will act as their transaction fee called as GAS. There is also a downside of course, since it is easy to create token, some use this opportunity to trick people, they are using this token to scam, and this will result to dumping of ETH. Nevertheless, ETH will have more demand in the future and will be like a bitcoin for sure.
