The things that will determine whether Bitcoin "wins" or not will not be the use cases where Bitcoin is supplementing existing infrastructure, but rather whether or not it can sustain and grow use cases where it replaces it. Even if those are fringe or even sketchy, that is what matters.

"Blockchain" initiatives at banks are just about implementing cryptography as part of solving larger technical challenges they have. Using Bitcoin as "rails" isn't there yet. Using Bitcoin in places where only Bitcoin makes sense will make it a cockroach, and open protocols that survive tend to become important.
