First of all welcome to the forum. Secondly what you can do is that get a Copper Membership here in the forum in order to post pictures and make the announcement thread look for attractive.
The bonus is for just 10 users ? That’s to be honest very low. If you could possibly increase it to 100 users anyhow, then surely some potential users will join the site and give you a good feedback.

Moreover you also claim that you the first to offer live support at your site? But I see stake.com and many other sites already do this before. It’s nothing new.
Great to see you guys are accepting major altcoins to play with. Just now you need some good promotion campaign to get potential gamblers.
Wishing you best of luck for the future.
