Not really, someone has been betting big on the 97% so actual winnings are quite low! The 'won today' lists only the payouts but doesn't subtract the bet amounts. Same goes for the leaderboard. In this case someone bets 50 btc on 97% and the won today lists it as 50.2211 when won but actually only 0.2211 was won.

On an unrelated matter: what's up with the low maximum bets? The max you can win at the moment is 0.125 at any given percentage. It used to be much much higher! AS recent as May you could win 65 btc on a single bet. Did the site loose a good part of its bankroll?
