OP, this link you provided when I click I see this:
http://nitrogen.eu/I think you are talking about this site:
https://nitrobetting.eu/To be honest I'm not surprised by this decision coming from them, if you're really talking about
https://nitrobetting.eu. look at their thread:
Nitrobetting.eu - Unmatched BTC Betting and EntertainmentThe casino representative here on the forum does not post on their ANN Thread, but has constantly created random threads in this gambling section, which in my opinion could be because the casino does not have enough funds to pay for advertising, which of course advertising does not always guarantee good results, by this I mean that it is possible that the casino is facing financial crisis, a red flag that people should be aware of, because looking at the past of the casino, looking at the behavior of the casino representative and adding That's what you wrote about all free contests, so my thought that they are probably in financial trouble may be right.
This doesn't mean that I'm accusing them of anything, but that people need to use the casino with some caution, something like if a person deposited $100,000 in the casino to play, then they start depositing $500, play and if win withdraw, then deposit again if you want to play. I know some people may think I'm exaggerating, but there are certain signs that should not be ignored and should be seen as signs to be careful from now on.
