You have to do extensive promotion to get referal under you who actually activates as it is hard to get anybody to pay 22$ for membership only. So overall cost of advertising will be more than your income from referals. I like to remain quite far from this type of pyramid structure.
It is indeed a lot of hardwork and promotion to get people to sign-up and activate. However I've also known people who joined MLMs such as Forever Living Products, USANA, JEUNESSE, etc who paid hundreds of dollars for a membership and yet earn a tiny fraction of that in commissions. I usually stay away from MLMs / Pyramid too coz I don't know how to sell lol. This happened to be the first one since it's all about bitcoins and I thought it's not too bad to try with $22.
