This isn't exactly and MLM but it is absolutely a ponzi. I thought you guys might enjoy some of the commentary on it as it is the completely opposite of the MLM "we love them they are the best this isn't a scam!" posts.
The basic community commentary is "This is a ponzi lets see how much money they can flip before it explodes!" It is an interesting look into the mentalities of the first adopters of other scams. I think it is interesting that in this unique situation the losers are seen as those that get stuck holding the bag, not innocents that poured their life savings into something they truly believed in, as they aren't attempting to mask the ponzi behind complex systems and confusing lingo.
Also, interestingly, when they do take the money and run, it will be extremely hard to track them down and unlike the Zeek issue where those that profited over a certain amount are being sued it will be nearly impossible to track down anyone that profited off of it.
I just find the open mentality of the community interesting, different from the normal scams. Probably because the crypto world has watched so many people take the money and run, it is expected in almost any venture now.
