I would prefer to use a bitcoin wallet over a bank. But since lack of adoption of bitcoin as of today, I have no choice but to use a bank as well.
Maybe one day it will be possible for us not to depend on a bank anymore.

I am not using bitcoins as of right now. I am holding for the moment like most people are at this point. I might sell when I think that I can benefit of the profits I will make.
Until then I will be holding and earning as much bitcoin as I can, I would have to rethink about buying bitcoin for now.
