According to the most rumors, last this year Ethereum will pump again. Noone can't perfectly says what will happen. Just will need to wait few months, now only patience is the key.
It is not even the first time that we will get to see Ethereum in this shape. It is a normal thing as the whole market has been in a downtrend state for a while, which I believe those who are smart enough, will know that this is a market they should really be trying as much as possible to get into now. It is just a matter of buying in now and being patient for the move to come, and those who have never been patient are the ones who usually end up not getting the best of any market in the long run. This is a good chance and opportunity I must say for those who are smart enough to take it.
I still really hope that at least at the end of this year it can go up to $ 500- $ 700 is very good, until today ethereum prices are still stuck and does not have a definite movement.
End of year predication is just based on how bitcoin is going to perform in the same time frame. Still, I suspect ethereum may not follow bitcoin as it has done in the past. Last time when I had observed, BTC was in down trend whereas eth was in finding new ATH. Hence, expecting by this year end may disappoint you but it will surely have $1k levels again still there could not be any assured thing as usual in crypto world.
