The bet results are based off BTCC buy price and the volume. If any combination of the hash with those values in the same second is a loss, then crazybtrade can state that they used those values to calculate the bet and that it was automated.
It's not to say that the bets aren't automated, but there's the chance for larger bets to be processed manually (and then used to scam)
all bets automated, 0.0005-0.25
BTCThere is no link between that transaction and PuraPuraBego.
Although PuraPuraBego may have stated "although this double spend, fund will be filled back to my account", that could have just as easily been a miscommunication error - it's heavily implied that instead of double spend, they meant "unconfirmed input".
I'm not sure why you wouldn't want to refund (at least some of) the bets given that they were confirmed. Do you seriously mean to say that PuraPuraBego had won all 9 of those bets? Do you have the history for that?
I'm asking the question again:
How did you manage to "lose" your wallet? It couldn't have possibly had only one address in it (which was the one that gained the 0.9 BTC) could it? If it in fact
is only one address, then how did you initially fund the wallet?
this does not matter: lose or win. we not pay cheater.
This happen real-time.. when i post about, bets has been not confirmated.. after my post he said that will be ok. but this fact of double-spends
Since your game is real-time based and bet was confirmed later, maybe his bets didn't processed in your site but in that case at least you should have refunded BTC. Just because that you saw it unconfirmed and the game didn't rolled doesn't means someone is a cheater.There are many onchain games like Luckyb.it etc. which only rolls the game after confirmation but I have never heard any onchain games running theory of not processing/refunding bet if the bet was confirmed after some hours or took time. Also I think your game wasn't developed to process stucked transactions in which I think bets above of PuraPuraBego should be refunded atleast.
