Ethereum has a future if they can keep with the times and focus on innovation, why was ethereum going for 1400 at the peak times instead of 8 bucks like it started the year? Because, it was capable of creating a reason of purchasing, you bought eth to buy crypto kittens, you bought eth to fund ICO's which was billions of dollars in funding, you bought eth to build on blockchain app for it.

Basically, there was a lot of reasons to buy etheruem, right now there looks to be none, if ethereum team can create a reason once again so will the people follow and buy ethereum however if they fail to innovate and create new stuff than eventually they will be out of business and ethereum will go low while some other coin go up. I am not saying it will be zero but look at litecoin, at one time litecoin was the second biggest coin, silver to bitcoins gold, now its out of fashion, same could happen to ethereum.
