Banks being hacked piss of people, pissed off people may or not may go to Bitcoin after that. I think its a minority until its more mainstream.
some of them will not decide to go with bitcoin or anything else, but simply they will put their money in their house in a safebox
so don't be so sure about the fact that the falling of the banks might help bitcoin's adoption, if they cannot trust banks they will not trust anyone with their money, i know their mentality, because it was mine too before knowing about bitcoin...
Thats not an option in europe from where I am from. We are disarmed in europe, you cant even defend your home if burglars come in and even if you do the fucking law will put you in prison for daring to defend your home.
Best option in europe is to just not have valuables at home to not become a target. Bitcoin is an ethereal object, you can sure steal my external hard drive where i store my priv keys but good luck breaking triple encryption fucking burglars.
