How not to start and run a gambling site;
https://bitcointalksearch.org/topic/tothemoonis-moneypot-in-space-825009The nature of bitcoins, being anonymous, coupled with the internet being fairly anonymous as well, leads people to act in ways that they probably wouldn't if they were running a bricks and mortar business.
The problem is it can lead to a "fuck you" attitude, and like some people previously mentioned, trust is the all important factor.
I can only guess at what your going to face, in terms of public relations, but its safe to say the following will happen;
You're going to get a lot of people saying your a scam, why? because they can and their bored and trolling.
You're going to get a lot of people with problems that might be your fault might be theirs, most people will blame you anyway.
You're going to have to be patent with everyone, unless they are actually trying to scam you, because no one cares you're having a bad day.
If the immediate response is to say "fuck you" to any of the above, you've lost, because while you may be anonymous, your site isn't, it is a brand.
And it's your sites brand that you represent.
You are the spokesmen and if people don't like you or your attitude, then they're not going to like your site.
