5% a day = 35% a week.
If there was such a method that were actually legal, we'd all be rich. There are people still living in the street, so no.
Even worse, banks here offer you a massive 0.6% interest on your savings annually. I can remember letting my money rest in my savings account for like 4.5% years ago. And now the interest is not even worth making jokes about. That low is it. And the current 0.6% interest rate will be lowered to 0.5% within 2 months!!
They trade you money with other banks and get alot more for it at a higher interest for lending it out
So that 4.5% interest are just pennies compared to what they get for trading with your money.
Think about that the next time you look at how much interest you are getting from holding any of your money in a saving account.
I am fully aware of that, but it was just to show what a huge difference there is between right now, and how it was back then. No one is going to hand over a certain amount of interest. So yes, compared to what the bank does, my old 4.5% is nothing more than a joke.
