I still think it doesn't hurt to try out and approach some new altcoin casinos as they always need new players. We need atleast somewhere for casinocoin holders to spend their coins so we have a use for it.
What are you waiting for? How many casinos have you already approached.
Although the notion of "having a place where to spend their coins", doesn't quite work, as I already pointed out. The CSC would gradually flow into the casinos' hands due to the house advantage and then they would be stuck there, as there is no liquid market for them.
I would like to approach them but I'm just a nobody. Most exchanges and Casinos would only take you more seriously if someone from the dev team approaches them.
When people gamble and loose the CSC, they will buy more to keep on playing. This would keep the demand up.
And once we get accepted at 3-4 Casinos, most exchanges will take us more seriously because there is a use for this coin.
More exchanges also means more demand.
