I haven't blatantly called you a scam. I've pointed out facts and offered you a way to get around the trust issues.
If you don't want issues, simply fund the bank roll with your private investments you currently have. You don't need more funding. Coming from someone who has been in this Bitcoin gambling scene a while, increasing your max bet from 5 BTC to 20 BTC is going to make pretty much no difference in terms of profits. Increasing investments however will dilute your profits.
By wanting investments you are only lowering your profits. That's if your end game plan is to not run off with funds. Considering you are completely anonymous and have no reputation to lose, running off with the funds seems like a logical route considering the profit incentives.
Good luck with your website though, I'm out.
On the front page you have posted huge red writing (now made just bold, appreciated) saying "If history serves us correctly, everyone who invests in this will lose their money." and that you are "always right".
I respect the warning to users to invest and gamble smartly, but I think it's a little over the top and unprofessional considering there is no actual reason to not trust us. But that's just my opinion.
No one 'has' to invest. They can simply gamble and treat it as a site with no investment options, I believe that should be up to them. We are not going to send 490+ BTC to a user we don't personally know on the bitcointalk forum. The investors that are currently in trust me and the site. Others can make their own decision and within time we hope we can grow to have more users doing the same.
