if I have to choose I still choose for the bank because your money is insured if something happens and I also do not trust a unstable currency that can fall down on a day..
I think its too risky to do this!
That's true our money is more safe with the banks as if we our bank account gets hacked then banks will help us in recovering our money but the same is not the case with bitcoin wallet, once bitcoins lost its impossible to recover them.
if a person will make the extreme security for his bitcoin wallet and will activate all the keys for strong security then itis not possible for someone even for a well trained hacker to hack your bitcoin wallet. So you can rely on bitcoin wallet.
