Money deposit

[The Raven]

Have you ever decided to deposit your money and generate an income on year basis? It is a long waiting time but it is a sure profit. The concept of this is very simple. In order for banks to give loans to others, they need money. So, when people deposit money there, bank promises to give them small percentage more after a year while they use that money to give loans to other people. Of course, the percentage they take from other people is 20% or less which is insane income. 

Now, that is not important for you, what matter is your deposit money. More you give, more you get because it is based on percentage. Thoughts on this?
