I read recently, that Bitwala, an exchanger in germany is planning to provide a crypto based bank account.
https://www.bitwala.com/And I think, also traditional banks will jump on train.
It's nothing more than a potential service that they are planning to offer, which at first requires them to obtain several licences for. No licenses means them not being able to offer what they have been planning to offer.
And even if they do manage to get everything up and running, how long will it take before certain parties will withdraw their support? Bitwala in this case depends too much on external factors.
With how regulations change and are constantly being added, financial institutions and services will have to adapt each and every time, which is something you just can't fully depend on.
Too many potential obstacles that you have to take care of and deal with, which isn't something I consider to be a viable long term option. I really wouldn't be surprised if they eventually decide to just pull the trigger beforehand.
