Honestly bitcoin is way better than banks, know of someone whose account was hacked and a whole sum of 68million was removed from the person's account.
You don't expect a basic thief or a basic bank hacker to have the mindset that the person they are about to steal from has everything in bitcoin, most of them only know of bank savings.
I understand that a person can be forced and obtained of their secret pass phrase by a robber but that would be 1 robbery case out of 500 cases. It is still very rare for it to occur.
So bitcoin is still the best, it is the last thing any thief will want to think of.
