With Ethereum having the backing of Fortune 500 companies, I think it has a long way to go. I see it at around $800 by the end of 2018. I agree with you on Ripple and do not thing it will ever move out of the range it is currently in ($0.25- $0.35). Bitcoin's price can really shoot depending upon the outcome of 1st August's events. However, chances of it crashing down are slim. Let's see what happens in the time to come.
