I think we should wait for the official announcement before concluding that the gambling site has been hacked. What was seen from Gandom was unauthorized connection on one of their automation servers.
It was said that users funds are safe, but which we can not believe for now because of the transfer of such amount of money. So we can not believe the gambling site wallet has not been hacked until an official statement that says otherwise.
Edit:
If Felix Römer is the founder of Gandom, the $3 million hack is true according to his post on X.
$3 million is the amount the founder gave but some sources say that it was slightly higher than that, I have reasons to believe that he only put it at the figure so players wouldn't fee like the casino is going bankrupt or something. You are right about not believing that the players funds are safe just because they said so, it is possible for them to be going through a serious set back at the moment but trying to keep it cool so that players won't lose hope in the casino. They are currently back online but we still await further informations.
Well that is the best thing they could do for now, then see what are the other counter actions done.
But since they go back operating now, I think best to look if Gamdom operations goes back to normal or their players will encounter withdrawal delays or other issues.
I don't see people complaining about their funds and it seems they handle this situation well.
Guess lets just see if they recover like Duelbits or they start to fall down after they experience some tragic incident.
