If you want to save your money all you have to do is to invest and make your own bank account so that you have a money that can use in the future.
I agree with you sir. If you really want to save money on a very long period of time and you want to earn as well, it's better for you to invest it in a bank so that time goes by the money that you've invested is growing, like a land time goes by the price of the land is increasing.
