I think this would be the taughts of uninformed individuals because it's easier to trust something when you have no other alternatives or something much better. As you can see, I stroke out all because they is not even one worth convincing about why people should store their money in the banks....

Over time, the banks which were meant to save our money for us, becomes greedy and worst than the thief which we hide them from, there's no such thing as secure for people who takes unnecessary charges from us on every transactions we make and the money we store with them.
Sometimes you get your money frozen on the air and when you get to your respect banks they give you shit reasons which would have been solved by their systems without you coming over .. that's not peaceful, it's obviously stressful and the same banks will go behind our back to loan out these supposedly stored funds of millions of individuals to big companies and make money for them selfs but fail to pay us interest like they are supposed to..

so I don't advice anyone to store a dime in banks... Divide your portfolio, make your self your own bank so you don't have to answer to some centralized thief's every time you want to take money.. bitcoin still remains the best digital currency for that and over time your funds or investment grows, while entrusting it with BTC ..
