For some people who understand technology well than it will shaken them ofcourse and could perhaps make them trust more in BTC but for someone that is blind on it then it will create a massive doubt for them, basically because their thoughts is that if such secured banking system could be hacked what would prevent a simple BTC wallet to not be hack
Also that people tend not to trust themselves into securing their own possesion which is why most people trust bank to secure their possesion and it takes them less trouble to secure things by themselves
