As for the calls to "change something", if he's cheating then limiting the maximum bet won't stop him winning, and if he isn't cheating and is just lucky then limiting the maximum bet will only slow his inevitable losses. I don't see how it helps in either case.
One thing that I can change that will protect investors is whether the site is up or not. If I take it down they won't lose any more. But I suspect that most investors wouldn't like that decision. They want the site to stay up so they can win their coins back again. The ones who want this to end have the option already of divesting.
I'm quite tempted to just give up on this whole thing. It looks like the site is simply at nakowa's mercy. He's promised me in the past that he won't play any more, but never sticks to his word. So what do I do? Continue to let the investors take these horrific losses?
Dooglus, if you can find ways to demonstrate / reassure yourself and investors that the RNG is good and the site has not been compromised, I think that's all you can do.
This event sucks in the short term, but in the long term, assuming the site/RNG are secure, all this publicity could work out in favor of the house.
