Is there a problem with your payout system? I request a payout earlier and the transaction is failed. It seems like the wallet is out gas.
How much are you tring to withdraw? is the amount under the minimum withdrawal requirement?
https://windice.io/faq#f34Admin got our offer, still no response tho. Joining our site would be much easier and faster, then implementing in-game exchanger, and with some other benefits along

It is becoming popular to add in-game exchanger, this gives easier effort for everyone who wants to convert their payouts or balance if its needed.
I haven't come across any such built in exchanger along with the gambling platform. Maybe that could make the platform a step ahead of the other gambling websites in advancement. Windice right now easy accessible and has got the simple interface that anyone could make use of, but adding more features might make the page congested.
