We believe that the evidence provided is sufficient to suggest that a double spend was attempted.
I don't think you have presented any evidence of a double spend attempt against DirectBet.eu by the OP.
When you send out a transaction with extremely low fees and a few hours later double spend it with extremely high fees, and you then repeat on the same pattern over and over again, that can not possibly be wallet misconfiguration or user error or fee saving. That's intentional fraud.
1. This is not what happened.
2. This would only be fraud if the sender of the original transaction received some kind of benefit from the original transaction and the recipient of the transaction provided that benefit while relying on a 0/unconfirmed transaction.
That being said, even if you disagree with the above, please note that Bitcoin Sportsbooks realize that due to the anonymous nature of Bitcoin, it may not always be possible to show to the public bullet proof evidence of fraud attempt.
If you cannot show the public this evidence and keep the better's money anyway, then you will be viewed by the public as untrustworthy.
For this reason, there is a standard universal rule among Bitcoin Sportsbooks that entitles them to confiscate coins when they believe a fraud is involved. Notice that we say "believe", not "prove".
So you might be able to weasel your way out of a lawsuit, but this does not change the public perception of your site if you have confiscate money like you have to the OP
Here is the rule of NitrogenSports :
If Nitrogen Sports believes that any customer has intentionally acted in bad faith or has engaged in fraudulent activity, Nitrogen Sports reserves the right to take any steps necessary.
I have personally trusted Nitrogen Sports with large amounts of BTC, while sending them transactions with 0 fees, placed a bet, won the bet prior to my deposit receiving a confirmation, and then withdrew without any issues after the transaction confirmed. Sometimes their spam filters will prevent me from getting instant credit for a 0 fee transaction so I will wait for a single confirmation.
I would not however trust your site with any of my money if I wanted to place a sports bet.
During the past 2.5 years we have developed extensive knowledge, experience and tools that allow us to distinguish between fraud attempts and regular bets.
So you have never fallen victim to people double spending loosing bets?
Did on what day directbet send agreement? Never.
As we informed you from the very beginning, in order to proceed you first need to pass a
standard KYC procedure to authenticate the contact information that you provided for the agreement and we will then prepare the agreement for you to sign.
That is BS and you know it.
