Two days have passed since I requested payment. I wrote to support Betnomi to find out the reason for the delay, but they said they had no information 
I also wrote to bitcointalk user betnomi.com, but even there I was not informed about the reason for the delay.
Again this long delay for withdrawal repeats for Betnomi, and I am not surprised they are still doing manual withdrawals.I also wrote to bitcointalk user betnomi.com, but even there I was not informed about the reason for the delay.
Maybe try talking with support but you will have to wait for official stuff to reply something in forum.
One good thing about Betnomi is they are not so strict with kyc like some other casinos.
