No, It does not happen because banks are fully secured eg: central bank etc. So there is no need of adopting BTC..
From an economic sandpoint, I don't think there should have a difference between money being stolen because of a hacker, and being stolen because of a hair cut/capital control/inflation. (insurance does not protect against this)
You can ask to an argentina guy whether he prefers peso to BTC.
The only difference is that stealing btc by hacking can't happen on a global scale.
