Hackers will always be social engineers at the first place, not magicians, and will exploit human stupidity.
Bitcoin is sensitive only on bad karma. Not on brute force! Bitcoin as idea is ideal of freedom, and if they cannot take your
freedom, they will lie about it in worst ways.
I think even hacker will not hack all bitcoin wallet although they can. But hack by any negative purpose is still include in cyber crime. Probably developers are create some thing to make bitcoin stronger against hacker.
