Thanks!

I noticed another BitCoin doubler, but it doesn't say whether the coins are ever returned in a loss, instead of your method "give lost money back, but take a punishment %"
So I think there are only two....
The default game was:
If no more players (entries) come in 7 days, the game is over and no one gets any money back (if they didn't get doubled yet).
My game is:
At the end of the round (midnight) it will take what the bank has left and split it between each entry that hasn't gotten paid (which is weighed by how much that entry put in), minus 2% per user as in the FAQ.
