There is no place to make an safe investment, if you are investing your money then you should be mentally prepared with the risks associated with it.
This is very correct! Even with a bank that is regulated by the authority have risk of becoming bankrupt. You must be prepared and should invest what you can afford to lose. There are lots of scenario where bank closure leaves alot of their client broke. Because all of the client is in that bank as saving, when this bank close and declare bankruptcy they can only refund a portion of your investment.
In my country if you have saved your money with Government sector banks then your money is safe as those banks are into existence since 100 years and they will never go bankrupt for sure.
