It was not a good ponzy formula except for the first 50 maybe. The way of using bitcoin and the blockchain was good so maybe some better long term concept will emerge out of it.
i could think of a game where every one can only deposit a fix amount and it get distributed randomly between x/10 of the participants. Some account will win some will lose.
I like it. Something like that could easily work for a sustainable linear (non-pyramidal) redistribution scheme that was still entertaining.
spended 1 BTC, got back 0.5422... i think they got 50% of the fundings.. some users added 30 BTC or 50BTC so that was huge win for this scammers

This actually adds up. Checking my copy of received.txt, you were depositor number 65. There were 140 total deposits in the game so there were 75 beneath you. These 75 show up in
blockexplorer. Furthermore, the amounts of those distributions are correct. I added two columns to received.txt to make
this. Sum the last column to get your 0.5422.
