Again it seems to me that I will buy the pack, then refer someone and when the user will buy any pack I will get the bonus? It looks like pyramid schemes, does not it? That means they take money from me, then they take money from my referral and pay me. One day they will away with all the money from the investors. Very risky investment plan Imo. We should aware of it.
You cannot get referral rewards for just referring, your referrals should invest because that's how a Ponzi scheme works, there should be money coming in so those who are in the upper level can cash out if no money is coming in, then it's the end of the road for the program, everyone is obliged to refer and invest.
