So you want to play poker but for some obscure and incomprehensible reason don't want to have anything to do with Bitcoin
Not me, of course, but, most of the people don't want to have anything to do with Bitcoin. They avoid it like the plague, sometimes to the point that they don't want to even hear about it. I know this from my own experience, and I think you know this too.
I'm talking about regular people, people with lack of knowledge. Casino owners are not like them. They are either educated themselves or have educated advisers, so they are not afraid of Bitcoin, but they must take into account the views of their customers.
So, I still think that, for the moment, the the best way of implementing Bitcoin in land based casinos is exchanging them for chips by casino cashiers.
