In the next few years this will not happen, maybe the etherium and rise in price but not so much to achieve the value of bitcoin, everything will be decided in the long term so we will wait and watch all this
The topic is quite interesting. I hope so ETH can reach value of BTC. Because I like to trading with ETH, it's pretty easy and simple. But that is just a dream, the value of ETH can't ever reach BTC. 
Everything is possible and come to think off that bitcoin did able to experience those struggles when it was just new and come to think off that ETH is only few years old which it do have still a big area on being developed and being adopted even more. We cant able to predict possible price ranges but seeing on its track we would able to see that possibility on hitting those price ranges same as bitcoin is possible. No one knows on when but its possible.
