I do not know if it is greed, or if our people just ignore all obvious signs of a ponzi. No matter how much ponzi organizers try to disguise and hide that they are not a ponzi, there are some common basic signs that gives them away.
These obvious signs are what I hope we can discuss about. Some of them that I have noticed are;
1) You always need to bring someone or people.
Because it is a pyramid scheme that they hope to benefit from, there is no way it can thrive without you bringing someone in new.
2) They sometimes associate their scheme to an international person as the founder, or claim it is also done in other countries.
Associating the scheme with an international body of person gives it some level of sophistication I bet, This is why they always do it this way so that they can attract gullible Nigerians more who always have the thinking that something from an international body is always better than what is present in our country.
3) Always the promise of quick returns.
What other signs have you noticed?
One of the things I have noticed with the Ponzi scheme is the convincing comments commented under the said advert, after over hyping the scheme. Once I notice mostly positive comments on an adver I consider it to be a Ponzi.
I also know a Ponzi scheme's when ever an investment advert do make a huge promises and assurance that are too good to be true or hard to believe, like asking someone to make an investment of 100,000 and get the opportunity to withdraw 1Million in a week.
I have also noticed that a Ponzi scheme always give a huge reward for referring someone, I have seen where a 6k referrer reward have been given to someone that invested 15k which is almost half of his investment. That is the sign of luring.
