I think,in bank our money is safe because many authorities are behind which have expertise to handle the money. No doubt ,banks use our money and they invest that money in stocks and bonds which are risky and from our money they buy assets by which they get benefits but now is time ,we have to understand the the whole concept about the money and bank and how banks use our money and how they double and triple our money by investment in assets and how they get benefits from our money? Every person should learn books and they should be habitual of reading books because this habit will give them excel in life.
The bank knows very well how to use every money of its customers in several things that can make them profit because it is very impossible for the bank to just keep the money of the customers without using it at all. Because apart from the bank who has to pay each of its own employees, the bank owner also really wants to increase his wealth through other important assets in this world so the bank will never stay silent by saving money but they will always move to make money multiply through their own customer funds.
