I would be very careful with predictions for the price in two years period. For a bitcoin this is a long time because market is changing very quickly, I would say faster than before and it can't be predicted in what direction situation will develope.
We have already touched 20000$ so it looks like this would be easy to reach again and I think we will but maybe this time we would have to wait longer. But once we'll be there again further progress would go easier.
