I had another talk with the Gamdom support team and I can't say they have helped in resolving any of my questions and doubts.
I wanted to know how exactly they process withdrawals and asked to speak to someone who knows. The support agent said she doesn't have that info, so I spoke with her. I asked what happens with the Bitcoin deposited to the casino? Do they convert it to fiat, a stablecoin, or does it remain in the original currency. She didn't know and couldn't answer that question. I asked why is the requested BTC withdrawal amount sometimes a little less and other times a little more than what the player asked to withdraw. Support responded by saying that the players receive exactly what they requested. Later during our talk, she says that the amounts can change. I informed her that those two statements are contradictory because you can't claim that players receive the exact amounts only to say that those "exact" amounts can be different. She said she didn't understand my original question.
I stated that if Gamdom doesn't convert the deposited BTC into fiat or stablecoins, it makes no sense that withdrawal amounts change. If I have 0.003 BTC in my account, why is there a possibility that I will get more or less than that if you aren't doing some swaps back and forth that causes the difference? Of course, she couldn't answer that either and knows no one who knows. When I asked if I could speak to her supervisor or another colleague, she said there is no one else there.
To conclude,
Gamdom will not be added to the table for the time being.
Since I don't have anything against the casino nor do I believe them to be fraudulent, I will try one more thing. I am going to tag yahoo62278 in this post. He runs their
signature campaign. @yahoo62278 do you know anyone from the Gamdom team who knows more about their internal operations? Someone you spoke to maybe to set up that campaign of yours?
