Only thing that can really stop this is a blow to the fundamentals of Bitcoin, which are legality and technical reliability. As long as those are in good shape we will very, very likely see Bitcoin grow as both a store of value and a medium of exchange. And this will also mean that the price will eventually recover, big time.
I know that, personally, I've been looking for a store of value that isn't precious metals. That ship has definitely sailed. I'm also a pseudo-Libertarian nerd, so of course Bitcoin is a natural fit for me.
Seeing more and more tools trickle out that bring Bitcoin to the layperson, I do not believe its niche-dom will last long. I give it two years before Bitcoin is a household name. Not to say everyone will use them, but they will all know what it is.
