First things first, cheating is absolutely not allowed on this site. If you get caught cheating, you lose your account and all coins. We are very clear about that in the terms of service. We never cheat our users, and expect the same in return.
Below is an example of a recent double spend on BVC:
https://archive.is/hR49i
The 2.1 BTC was sent to 16nuq6EU9wRgpXK9BLN1iz5hEWb2Xg966o which is a deposit address on our site. The transaction has a very miners low fee of only 0.000001 BTC, which means that it will generally take a long time for the transaction to get confirmed.
However, this is the transaction that actually got confirmed:
https://archive.is/T1lGY
This new transaction has a higher miner's fee, and because it made it into the blockchain, it invalidates the first transaction.
This means that the user was able to credit his account on our site, play the games on our site, and then invalidate the transaction as though it never happened.
The reason why the user decided to try to invalidate the first transaction is that he played a single 2.1 BTC game of Dice and then lost. He can then revert the transaction and get his coins back. If he were to win in that game of Dice, he just lets the original transaction continue until it confirms and eventually he can withdraw his winnings.
In the past few days we were able to find quite a few double spend attempts with similar deposits, mostly coming from a handful of addresses. We were able to stop most of the attacks by making it impossible for the user to withdraw his winnings.
A lot of the double spend attacks were coming from this particular address:
https://archive.is/5bTKf
If you follow through some of the transactions you can see that blockchain.info is declaring them to be double spends.
So, we know without a doubt that some accounts were used for double spends. We can then compare these invalid accounts with the account that unibtc4real claims is legitimate, to see what similarities there are. If there are enough similarities, it should then be possible to associate this account with all of the other illegitimate ones, and declare this to be an attempted double spend.
I will list those similarities now:
=======
The double spend accounts all used a tiny 0.000001 BTC miner's fee. Unibtc4real's account also used a 0.000001 BTC fee.
The double spend accounts were created around the same time as Unibtc4real's account.
The double spend accounts played Dice, betting the full balance in giant bets. The double spend accounts would bet 10+ BTC in single bets. Unibtc4real's account also played dice for enormous bets. His account has giant bets for 11, 12, 13+ BTC. It is rare (and risky!) for our users to make such giant bets on our site. The reason for doing this in a double spend attack is to quickly win or lose the coins so that you have enough time to undo the transaction if you lose.
The double spend accounts mostly played Dice with about an 80% chance of winning. Unibtc4real's account also played Dice at the 80% win setting.
The double spend accounts sent me emails as two different people saying that their funds were locked. However, I was able to see that they are the same person, since both of those double spend accounts were funded by 18zRryZwo7KefNGiFM5SLBsMVZA4TPwaLd . So the double spend user has no problem sending emails pretending to be someone else. Unibtc4real also sent me emails saying that his funds were locked, but he accidentally used two different email accounts with two different names, despite the conversation continuing as though he were the same person. So the double spend users and Unibtc4real both switch between different aliases.
The double spend emails were sent at 7:56 and 8:27 am (EST). Unibtc4real sent his emails at 7:46, 8:02, and 8:51. So if you sort the timing of the emails, you get 7:46, 7:56, 8:02, 8:27, 8:51. These times are all very close to each other, and could imply that it is the same person writing all emails within the same timespan.
=======
Each single piece of evidence is not strong enough to claim that Unibtc4real's account is associated with with the double spenders (the accounts that we 100% KNOW were double spending). But taken together, all of these similarities lead us to believe that Unibtc4real's account is controlled by the same person that controlled the double spend accounts.
So that's what we know. Any feedback would be great!
I will try to answer as much as i can regarding your accusations..
The address that you gave has no relation at all to my account. My deposit address on my account is 1PbKZZXPLVLzfhsKQxtXjujRa2a5vmpb9p, and looking at the taint analysis of my deposit address, it has no relatation at all to the address that you gave. You just throw out an address that has mutliple transactions with double spends and just say its me lol. But then again, blockchain says otherwise.. https://blockchain.info/taint/1PbKZZXPLVLzfhsKQxtXjujRa2a5vmpb9p
Regarding the fee..this one is ridiculous lol.. I did lower the fee for my transaction since, the volume of the transaction is big that it does not need a bigger fee. The transaction even tho with low fee, still has high priority due to the fact that the transaction is bigger. When a transaction has a low fee or even 0 fee, as long as it has high priority, its almost impossible to be double spent as miner's mem pool already seen the transaction and will reject any same transactions. The total output of my transaction is 18.362049 BTC which was big enough to have a lower fee and yet get high priority and won't need to wait days to get confirmed.

Regarding the time. My account was created/generated almost same time as the deposit which is 2015-05-13 07:54:54. I don't know what time you where double spent since you have not given anything that relates the time of my account to the time of the said double spents..
And about betting lol. How many people have bet the same 1 btc on 40% 50% etc.. Having the same bet as someone else does not mean they are the same person. I do admit that i did bet big amounts but not at 80%. I did bet basing on the max profit on the site which is 0.5.. so have a bankroll of 10btc, i bet on around 94.4% above.. Which contradicts your statement that i was betting at 80% which is not possible on betting at 10btc+..
Now regarding the email. I did emailed you and two email accounts, and i never said on my emails that i was a different person.. I first sent an email to you via my hotmail account http://s28.postimg.org/s226h3lq5/email1.png And after some minutes i thought that you might not be receiving my emails, so i did emailed you again on my gmail account, and i did literally said that i was the same person that emailed you from my hotmail.. http://s28.postimg.org/kjefuq4zh/email2.png
You never replied to either of my emails, so i dont see where we even had a conversation lol. I did sent you an email, but how can you say that i accidentally uses two different account. When i emailed you on my gmail account i already said that it was me who emailed from hotmail, So where is the "accidentally" there?
Also you said that you have mostly caught the double spent accounts and locked them from cashing out, IF i was the culprit, and i know that my doublespent accounts are already locked, then WHY would I even bother depositing another 10BTC if i already know that you guys are already on it...Someone that has a knowledge to double spent big amount of btc is smart enough not to deposit anymore and just walk away..
You have said it your self, Your evidence are all mere speculations and implications with no hard proof. All the things you have given are not even related to the account in question in here..
The mere FACT that my account which has 1PbKZZXPLVLzfhsKQxtXjujRa2a5vmpb9p as a deposit address are not involved nor was a double spent..
Im raising this issue to scam accusation since there is not hard evidence given, and the fact that my account was not a double spent transaction nor is involved in any. You can't just take my 10BTC with just mere speculations... I can only see three things that will end this, one, you unlock my balance let me play normally like any other players, two, give back my deposit of 10btc since i never lost that at all and we can part ways.. or three, i will have to live to the fact that 10 btc was stolen from me, and you will have to live to the fact that you have stolen 10btc from someone you wrongfully accused. and ofcourse negative feedback..
