I am not convinced if your website is really a provably fair casino in the navigation tab I really don't see anything just "home" Also you don't show any proof that your casino is fair like how to verify the bets, how the bets was made. This really a shady website.
We can’t say if the site is fair or not, until and unless some people personally verify it.
The main point is that, does the site has enough bankroll to fund winner’s winnings?
With that being said it will be great if the owner can sign a message from it’s cold wallet which has sufficient funds for the players.
Moreover if the owner can run some sort of promotional campaign here at Bitcointalk, then surely people will give a try to the site and will play there.
Still at first the owner needs to give clarification regarding the site’s Bankroll.
Waiting for a positive response OP.
