As a customer of theirs, the idea sounded pretty good, but stratching under the surface, they're not doing all that much I don't think.

“CBA will leverage Gemini’s crypto exchange and custody service and integrate it into the CommBank app through APIs.”

It's nice for the legitimacy of the space and shows the banks corporate opinions of bitcoin, where I'd seen in the past many Australian users getting accounts closed and blackballed by banks over bitcoin trading's. I just don't think I'm going to be able to deposit bitcoin and sell it directly into my account, but we'll wait and see.
