Banks are thieves, it's fucking unwise to entrust our wealth with banks, never should anyone leave whole portions of their money in the bank, if for any life sudden incident, at your dismissal everything ever owned are going down the pit, not a single dime will be transferred to your family or children. .
I use to hear about how bankers could go around the community inquiring and investigating about certain customers they are no longer seeing visiting the bank anymore and their account balance just been static without any transactions long enough from when they stopped visiting the bank. This inquiries is purposefully not for the interest of the bank account owner but to know if the person is deceased so they can steal the money from the account in that there family members none is also with knowledge about the very account. I never believed about this initially when I heard until a banker friend confirmed it among some of their bosses.
If you have accounts with banks make sure to inform your family members about them and the documents if possible, don't be extremely secretive so you don't leave your family to poverty while some strangers enjoy your wealth should the unthinkable happens to you in a flash.
