Just to add, if people are investing here that means they are ready to loose and gain both, which is same with all whether it is a ponzi or gambling site.
Does it?
Maybe it means they believed OP's claim that they
will be able to double their coins.
I think people take gambling games too seriously. Lighten up, we all know what it's about. We get that it's a ponzi, it's never a guaranteed profit (then again, when ever is gambling in general?). No one's going to cry about it when the owner does eventually leave. And if they do cry, they shouldn't be gambling in the first place. It's the nature of gambling, you win some, you lose some.
