It already is used as a hedge and will be used more in the future, although I don't think hyper-inflation is the correct term to use here.
There are 3 main factors that have always player an important role in bitcoin adoption. First and most important is what bitcoin offers as the only decentralized currency that can give you freedom. Second is the already increasing value of bitcoin that has made it a good choice to park some of your networth in. And finally when the previous 2 reasons exist and the fiat currency is losing its value (inflation) people have a strong incentive to look for an alternative which is when bitcoin comes in.
