My opinion on the matter
I found the answer and it is pretty much a legal scam. They call it multi-level marketing which basically means that you just have to recruit or convince people to buy starter packs from the company so they can in return sell it to more people. You earn your money through the network you build. Your network consists of the people you recruit plus the people they recruit. If you get enough people in your network then you can make a lot of money, but you would need thousands to do so. The problem is that this growth can't continue forever and 90% to 99% of the people who join lose money.
