I just deposited 0.001 BTC and do same basic martingale (base bet 0.00000500 BTC) and doubled my deposit in ~400 bets (2 times 200 automatic bets and a few manual bets).
And I won 0.0011 BTC so I requested withdrawal of 0.0021 BTC and status was pending.
So I wrote in chat asking what is wait time for withdrawal to be approved and got answer that double-spending is thief and my request just canceled?! What double spending?! I just doubled money, what's wrong with it?

Well, it's better to move this into Scam Accusations board because you have strong evidence against them,
https://bitcointalk.org/index.php?board=83.0Just scroll down and move to that appropriate board and quoting as well to show the images.
Probably someone will help you there and get warn others.
Moving it to Scam accusation board is the best thing to do, however it is fine here in gambling board since 999dice is a gambling platform. You can just make another thread on scam accusation board. As far as I know there are already threads about 999dice, so try to add this.
I've been seeing a rally about 999dice, it is very confusing coz there are people that tells it is not a scam site and the other way around. Now that you have proof, maybe it is the time to believe that it is really untrusted, spread awareness on this one. Looks like 999dice hate a instant doubler player.
