You wrote you have bank rolled just 100$? Or you have kept more funds ready, do you have any gambler reference?
So you registered your site in the year 2017 and you do not know any other dice sites strange find it hard to believe this.
I would recommend you to get a legendary vouch copy done, as this looks like the season of new dice sites.
You need to provide a sign message for users to know you have the funds. Good luck if this site is legit.
