I don't think the Bitcoin Casino is the right idea. We do not fully know what will happen with this currency tomorrow or even during the game itself. It would be a shame to lose a bitcoin and see a bitcoin rate twice as high the next day. I'm a stickler for an old-school, like the casinos described here http://www.modernaustralian.com/9165-the-future-of-gambling-sponsorship-in-australia. Dollars are still a harder and more stable currency. And there will never be a problem with payments and cashing, unless you choose a decent casino and not some passers-by.
