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?
