Which is why banks encourage people to follow the crowd and put in high yield saving accounts or normal saving accounts.
And they in turn use this monies to invest / trade and get more out of it, and pays the consumer low interest rates of 4 and below.
It comes with risk but if one knows how to manage it, the positive outweights the negative, which is why banks can do this year in year out. And the masses of people are like the sheep, providing monies to banks thousands and thousands of dollars for the banks to get richer.
So we all ought to learn and do it ourselves and make our monies grow.
