For sure. Since bitcoin is a store of value for the long run, and is pretty much exactly the opposite of what fiat dollars represent, there should be a spike in bitcoin prices if the fiat dollar collapses. However, the actual spending value of 1 bitcoin should remain pretty constant throughout the hyperinflationary episode if there was ever to be one in the next few years.

IMO bitcoin is one of the only viable replacements for fiat currency.

A fiat collapse would actually mean that people are forced into accepting bitcoin as a result, otherwise, they'd be holding onto worthless pieces of paper.
