They only stuck around a while longer to see how much more money they could get away with scamming from their customers.
From what I saw, they did not gain money by sticking around. They lost money in various ways. One of them being a lot of CSNO being sold in the buyback program. Another one was exploits. Other legitimate winners. Some players lost too, of course. They scammed customers only after I left and I doubt anyone played serious amounts there anymore at that point. None of that speaks for anything other than incompetence. If they did as you say, they should have packed their bags years ago. But they didn't, they stuck around.
When I spoke to investors about it, the ones I spoke with concluded that the point hope was lost when they let go of long-time employees like me.
EDIT: I'm certainly not here in any way to defend BitDice. I'm defending myself because there's only speculation and claims that I somehow knew what was going to happen. Yet there is no proof of that or of any ill intention on my part. It's all just speculation. I've given a solid amount of background from my perspective because I think it's important. I unfortunately don't have anything else to give. Despite the fact that the tone here is very accusatory, I've taken significant time to respond questions.
