Here is a interesting, hypothetical situation. What will you do if there is a MLM scam going on and it is in early stage. It is assuring 10% monthly return in bitcoins (of course it has that referral bonus part as well but it is optional, you don't need referral as you are getting 10% on your investment.). B'cause of it's early stage, people are investing happily and getting returns monthly. In short equation of incoming source money > outgoing money. By looking at situation, let's say this scam/scheme will go on two more year. There are some people who rip benefits from these kind of scams/schemes as they invest very early and in large chunk.
Will you invest in such scheme well before it vanishes with bitcoins/money?
Well, this is how really very important to us here to not take the risk in joining this kind of investment which is the ponzis scheme like MLM. A lot of people being victimized by this kind of strategic investment. Because the only who can benifits this kind of investment is the leader of the members. So we should be aware in this kind of investment.
