So, this will be a fun way to make coins. It will work in a pretty simple way..

You can bid anywhere from 1 coin to 100 coins, and pick a winner of a death battle..

If you pick the winner, your coins are doubled. (You get 100+ coins on top of the reimbursed coins you ponied up for the bid if you bid 100.. replace these numbers with your bid amount if you need an example.)

If your pick loses, you lose the coins you bid.

If it's a draw, everyone gets reimbursed.

Pretty Simple, and these will be tweaked as this goes.

Have fun, and don't screw up xD.
