Big/medium banks are never going to use Ripple, theyre only trying it out and will drop it then make their own technology (not de-centralized!)
Blockchain will change how we send money, but not through banks. Theyre completely against de-centralized control of financial system. We need blockchain solutions like Kora (

What's with the matter if the banks will not going to ever use Ripple? Cryptocurrency can stand on its own, what we should consider is the market, the decentralize market that is our foundation, as long as we, people and investors still believe on a coin, no banks can interfere or determine the future of it. No one but we are.
