To many scams like this happened from the past so hopefully new investor in the scene would do a research and learn something from history so that this mistake will not happen again in present times.
It's more of a system adopted by ponzi scheme operators to me , I can just conclude it a sibling to ponzi scheme scams even though it might not be directly scamming at first , I hate anything that deals with the referral system because you can never know how far you will get placed on their pyramid system, it's more like first come first serve, the lower part of the pyramid investment are used as payoffs profit to upper part of the pyramid and little to them back, when it collapses they suffer most of the loss.
Hence, most people are after bonuses ? getting more profits for their investment ( more like greediness sometimes) so people will continue to get scammed
, most people think they can trick the system and opt out ASAP they make small profit and not know how far they will be dumped on the pyramid plus how long it's being running... research helps too hopefully uninformed gets informed .
