Honestly, I think the longer they stay out the better for both industries (crypto and banking). Cryptocurrency answers needs that legacy banking could never and will never. Keeping banks from being able to shut your freeze your account because you send money to an exchange would be more useful, possibly. I just believe the longer they stay apart and the harder they make on-boarding crypto to legacy systems, the FASTER cryptocurrency/Bitcoin and the supporting networks will solve the technical frictions and grow.
