Yea some people worry about the 'wrench attack' not realizing there is one, and only one, way that will even be attempted is if a person is a walking billboard. Nobody gonna be robbing me for mine cuz nobody would have any reason to think I even know what a bitcoin is. I also dont have any wallets on my primary phone. That one is phone only and I dont carry the one with all my private shit unless I know Ima need access to something of the sort.
