where did you find this site  
I think I didn't see an official thread for it , and you are saying that you don't own it
the main page seems cool , but how can we trust this site since we don't know anything about it
and it only has 78 users with less that 7k bets
I prefer to stay away since someone tells his story with this site

Edit thanks to Panjul here is the thread
https://bitcointalk.org/index.php?topic=1102719.0 it seems that they launched their site today
