It is true that banks are very important and no one can refute that, however we must take into cognizance how the economic activities associated to a particular country affect the banks within that country.

For instance, there are major countries were banks have folded with lots of money of some persons who felt their monies were safe in those banks, this singular action lead to the death of many because, people could not recover from the money they have lost, then how trust worthy or how much trust can we give to these bank.

Now, when we talk about money and investment, I  recommend Bitcoin and other cryptocurrencies most especially Bitcoin, because these are world recognized currencies and have the ability to last long and as  inflation take place you make Good money from them.
