I don't know why people even consider participating in this
the chances to win are close to zero (thats even if the game is legit which I doubt)
typical greed based ponzi style game which is now in abundance, but this one managed to get 3+ mil worth of ether somehow
to me its just an elaborate scam with the creators able to take the win this way or another while the rest simply donate their eth for nothing
find a better way to spend your crypta, please
If this is legit then the chance is depends on how much money and luck you are because the last one that buy the key is going to win. Of course you are compete with every single players around the world so you assume this has a zero chance but in the end there is a winner which won huge amount of eth. But do not really believe what was happened anyway since there is no clarification about this game either
