This is my opinion.Banks won't make you rich.saving in bank can never do that,because of interest rate that bank gives you is too tiny.You saving will be simply be eaten up by the sleepy monster called inflation. As a example I will take ,When I'm in grade school,each day I received 10Rs (my country currency) from my mother.It was enough to by me 2 meals,but in now 10Rs enough to buy 2 candies.

Banks are just for keep your money safe!

Yes,if you invest your money in bank it won't make you rich so better invest your money in bitcoin because there's a great chance that you become rich in here.
