This is the most common scam that people easily bite, well, we can't blame those people who are the victim of this kind of scheme because all they just want is income. The problem is, they believe in things that are too good to be true, promises in ponzi schemes is obviously a lie, because who on the earth will give you too much profit by doubling the amount of money you invested to them in just days, or even week.

That alone is fishy as hell, but since it is all about earning big money, people take the risk, and they always suffer in the end of course, crying, asking for help to get their money back.
