I don't have any experience with development within the ecosystem of crypto casinos, though if you would like to read my opinion I would say that one of the most important things to keep in mind when comes to building and casino different from others already in the market is the graphic design and artistic work which is implemented on their user interface and on their original games; kind what stake does with their original casino games, basically, mixing their user interface with their games.
There was also a very well made dice website called Neodice which pulled off a very attractive design on their web and invited to deposit and play immediately.
So of you have the chance to hire a graphic designer with experience on Ider interfacesz it is something you should do if you want your service to bright among others who are more generic and copy/paste style.
