I'm not sure exactly how it would work but assuming the guy is running some kind of ponzi scheme, wouldn't he be collecting the fund for himself and then use part of the fund from the newcomers to pay the early joiners? And why would he put the price into bitcoin. And somehow you will need a lot of funding to actually push up the market to that scale. Like I've said earlier, I'm still skeptical whether the recent rally and this is somehow related.
