They will not pay it... And isn't their fault is the fault of the users for play in the worst casino they find.

I'm really sad about OP because the win was really huge, to bad you don't win that amount on a trusted casino like Bitdice, Luckybit or Just-Dice...

Next time verify how much has paid the casino in the past to a single user, that's a nice way to know if you can trust them.
