Im developing a gambling project.
How original

That's what Bitcoin needs, another gambling site... But Ok, it's a free world

I believe that users must trust a site where they bet their money, but a gambling site draws attenction

People who gamble is not a very good example of people who know how to manage risks

So you might get away with it. They will bet small amounts and lose them in hope of one big win, so there's not much trust involved.
