That ethereum coin is also I would like to invest this 2018, because it has many uses, it can be use directly as gas for tokens to be traded in the different sites , and it is establishing its name in the coin market next to bitcoin and aside from it, it is not big value when we want to invest unlike bitcoin which has a great value for investment.
Ethereum may technically allow all types of uses to be utilized, but the reality shows that no one really cares about them. Ethereum was nothing before people suddenly went crazy on ICO's, and these ICO's are still the main driver. Take away ICO's and air drops, tell me what use is there that people are genuinely interested in? Bitcoin doesn't have anything other than what it currently is, and that's more than enough for people to actively use it. The less gimmicks there are, the less there is to corrupt or bug, which is exactly why Bitcoin has been operating consistently without problems in the last years. That can't be said about Ethereum....
