As of withdrawing your winnings, I personally withdrew $700+ from my poker wins last year, without any problems, and within 2 days, approximately. I can't say how long exactly it took, but I don't remember any worries on my side.
Issue, small and a bit inconvenience is withdrawal request will take a little time for approval. Within 2 days as you said and as I experienced too. I did not experience more than one day for approval but a few hours, half a day. Maybe it is still issue with impatient users.
If Betnomi team can boost up their approval time, it will be very good for Betnomi users.~
I'm not sure if that's necessary. We all can wait a few hours(2 days max) until our withdrawal is confirmed. I personally have no problems with that. What we don't want is someone else logging into our account and withdrawing our money to who knows where. So, I'd rather they don't speed up the approval time. Let them properly check everything.
