A good looking casino site will be nothing if no one will discover it. This is where marketing comes in play. There are many ways to market a casino and not only via sig campaign in this forum but since bitcointalk is the most biggest crypto forum then they can expect to have a better result here than any other crypto forum.
A month long sig campaign can be a good start and they can evaluate the result. If they like it, they can continue extending the campaign but if not then they are free to cut it off. There's also forum ads which can be done via action and bounty campaign which can cover social media promotion and other promotion on general websites.
