I have noticed several times lightlord's unresponsive and payment delay.
All time there is issue I think the issue arises when the site make loss and cant afford the payment of hunters and/or gamblers. The issue of hotwallet might be true but it is difficult to trust as this type of staying offline as well as payment delay is usual fact.
I do not know if that is the case here. As far as I recall, there is a post from lightlord from a few years ago (I am sure I can find it again if needed) in which he disclosed his cold wallet addresses. The last time I checked, he still owned a significant amount of BTC (although he moved them to a new wallet in the meantime).
Both casinos owned by Lightlord have functioned flawlessly over the years. I am sure that the problem is not money, because if it were, it would not work for so many years. I am convinced that Lightlord is telling the truth and it is about his health. We only don't like how he is behaving at the moment, i.e. he does not inform about the situation.
