I don't know if you misunderstood the question or what. $10 being the new $5 means that the price can be stable at $10. It says absolutely nothing about going up or people thinking price will go up. Not in my opinion at least. This is how I understood it anyway.
Well, 5 turned out to be super stable and then turned into a huge rally. But okay, maybe I should've said "a lot of people believe the price cannot drop".
Sounds similar to "permanently high plateau," which has the exact same ring to it.
Well, can't claim to know the future. Let's see how it turns out.
