The prediction of the ether's destiny for next five years is not that easy, there other factors affecting ether's future. First bitcoin, then other new projects such as tezos and waves.
If ether survives after all of these things, it will easily reach up to $1,000 within 5 years. And the crypto market will go up eventually.
I think the Ether price could reach $1000 in one to two years if the past performance is any indication.
