If this can be maintained it is not impossible that Etherum prices can reach fantastic value and can even exceed 500USD by the end of 2018.
Looking at when this was originally written, it is important to remember the context. Up until around the start of November we had had a long period of several months of relative price stability across the market, which had many - myself included - believing that this was a strong signal for the start of a new bull run. It goes to show that - however much we pretend otherwise - we are all (again, myself included) making judgements in part due to wishful thinking as well as logical reason.
As for the short- and medium-term future, I think the outlook doesn't look great. I am optimistic that prices will recover in the long-term, particularly for ETH and other strong projects, but the question of how much of this is wishful thinking as opposed to logic is difficult to determine. I do think that crypto will still change the world, and this year is just a blip that will eventually be forgotten... but it is important for all of us to constantly question our own assumptions, and ask ourselves why exactly we hold certain opinions.
