So I made a prediction on Litecoin a few days ago that sparked a lot of conversation on the thread. It was very interesting reading the different thought processes and predictions. So I decided to do the same for Ethereum, however, I think that Ethereum has a chance to go beyond the 2-5k threshold in 2018, if only they would market a bit better. I believe that they need to get these new "coinbase noobies" to understand what Ethereum is and why it's significant if they want to stand a chance of getting above that threshold in 2018.
As always this is just my opinion and I would love to hear what yours is, check out my full thoughts in the video :

It's just my opinion though. In case it goes beyond that, well it will be better for every ETH holders.
