Let us see the scores of people in arena while spectating, and also let us bet gold on who will win. If you bet, say, 25 gold, and the person you betted for wins, you get 75 coins. The amount you bet is multiplied by 3 whenever the person you betted for wins. The cap for betting gold should be 500ish, and if the person you bet for loses, you lose the gold you betted.
