The first and basic things which a Gambler asks is that,
What's the bankroll of the site?
This means how you gonna pay your winnings to the winners?
A signature with the bankroll funds can really help you to get trusted gamblers to the site.
Moreover if you want your site should be overcrowded, then you need to make the best promotions possible.
Good luck

Actually most of gambler don't ask about how big the bankroll, but rather about how provably fair on new site (there is on their site)
