First of all, it is a gambling website.  You must pay to play, and you are not guaranteed your money back.   Who would have told you this wasn't gambling and would have recommended you post an active site requesting real payment in Project Development?  I'm guessing we won't get any answer to that, but you should move this thread to Gambling.  I am telling you it doesn't belong here, and you can quote me on that.

Second, I agree with shield132.  If this is a passion project, why would you produce a vanilla game probably written by AI?    Looks to me like a quick project you already completed to make secondary income.    I like the idea, but you should show us your passion and not concentrate so much on making $.  Did the lighting integration even take up any significant portion of this project?

Finally, no regulation, no oversight and no way to recover your money should the website have a planned/unplanned hack/inside job or whatever, which would probably happen at the peak of the marketing plan when the amount of bitcoin in their custody also peaks.     Your passion is not a developing project, and this thread does not belong here - your site should have the same exposure and chances as every other gambling site so newbies do not expect additional security.  Please move it.
