The oldest method is to keep it in a shoebox and hide it under your bed. Of course there is a risk of it being stolen or losing it in a house fire. People seem to take this risk so not to have the bank know about it thus not paying taxes on it. In a way that is saving money. Most if not all countries do not allow this way in saving money as it is illegal but if you are in one of the few countries that allow it then you saving.
But at the same time, the banks will pay you interest for storing your money in their bank. So technically you will be earning money, which is more spending money for you.
There are banks that offers great interest when you opened an account and save money there. This is what other people don't see because some of the banks in their location are vary per offers. Good thing one of the banks here in my country really offered a great deal when storing money there and we, my wife, are living proof for it. That's is only one of our ways to save our fiat money aside from our usual doings.
