As we can see, all these predictions differ from each other. That is why, we cannot trust anyone, and we must not also start to panic if a bloodbath is forecasted. Ethereum can go up steadily, it is the most likely variant.
We need to make our own analysis from their prediction so we could detect or know something that will give benefits to us.
Ethereum could be going to down for more for a while after the bitcoin rises and like the other coins, the ethereum price still not giving a significant increase of the price, so we need to be patient for a while.
But in the long-term, I think ethereum could be back to increase especially if bitcoin can get stable in one level of the price, the update for ethereum is release, and there is good news from the project, then it will give a chance for ethereum price to increase back.
