Seems very scammy, and even more so when you see the crappy website, and the fact that it's a new user.
You should start by signing a message from an address with more than $20k in BTC, to prove that you have the funds to pay out winners. You don't state how winners will be picked, so now might be a good time and look into a good provably fair implementation for your site. But, your stats also seem quite faked so I guess you were just hoping to scam some poor person.
The latest "winner" of your website is the address
1FfmbHfnpaZjKFvyi1okTjJJusN455paPH which contains/contained the BTC that the FBI seized, quite a while ago. Do you really think people will believe that the FBI is playing your lottery? Yeah, right.
GTFO scammer.
