This is definitely risky but I think it's a genius way of creating a Ponzi scheme game. Token economics and incentivization structure is very interesting. Had a bunch of friends who got in already and are almost breakeven. They understand the risk and are playing the game as an experiment to see how the game ends up and see if they can apply or take away tidbits from the economic structure of the game and experience.
The short version is supposedly not created by the same team and might be a legit scam. Have not touched that one.
