I'm here to say that not only I won 0.01 BTC in the Dice-Bet Wagering Competition and my account on Dice-Bet was credited with 0.01 BTC, but I also have successfully withdrawn this amount, without any problems or delays whatsoever. In fact, it was super fast. Thank you, Dice-Bet!

Regarding a shorter time frame for a new Wagering Competition, I think it's a good idea because mostly players are fighting for the top places during the last day, so why wait so long for the showdown?
