Bottom line is that no one should believe banks, that is corporation and they don`t care for little man, all they think about is profit and more profit, and if you are rich they will be nice if you are poor you will not be able to enter the bank.
Even wealthy individuals aren't totally safe. There are enough examples of how banksters notify the government of a certain country, that you have millions in potentially black savings stored there. It's a disgusting practice. Obviously, it's done to cash in rewards from the government in question. I am not a wealthy individual myself, but I am happy that Bitcoin allows me to store a good portion of my wealth outside the poisonous banking and governmental system. Thieves they are!
