1] Every village has a mad man ....and a thief! Banks are not an exception.
2] Your deposits are SAFE at the bank. When a bank is robbed, it is not customer's money that is stolen; it is the bank's [read shareholder's] money. The customers will get their deposits paid in full....
....unless the bank collapses under the weight of theft
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
