Everything is possible in crypto currency but no one knows when it will reach that value.I think ethereum will reach $2.5k by end of 2018.Ethereum price growth is slow because of its unlimited amount so we can't compare it with other cryotocurrency price change they are limited amount.
No ETH can achieve such prices, currently their prices only fluctuate at $ 800-1000 can not be higher. So do not be too high expectations, you will fail, give a moderate goal, do not greed
It all depends on bitcoin. If that coin is going to reach high targets of 30k to 40k dollars by the end of this year then if think, ETH can also touch 5k dollars in the least. ETH is a slow mover but it is a profit yielding coin. There is some reason for which it has remained at the top of altcoins since the beginning. It is pretty okay to expect high from this asset. It has never disappointed investor so far and will do the same in future.
