It is a scam and forbidden in many countries. Look out!
In some countries they can put you in jail for this ponzi scheme. I know that there a now some investigations by authorities in several countries. The so called leaders will have to account for themselves.
I hope that the readers will think very carefully when they consider to put their money and energy into this scheme. I am not a personal victim of this ponzi scheme but someone who inform and warn authorities.
This must stop because a lot of people have lost their money. For example a lot of poor people in South Africa and the Philippines. You can watch some examples in a BBC documentary. You can find it on Youtube.
A ponzi scheme will always drop down. It is not the question if it wil drop down, but when it will drop down.
Take care and stay safe!
