I have no idea if casino will ever accept bitcoin as exchange for chips that is used in gambling.
THEY WILL, some of them are accepting bitcoin already!
1, Online casino, LIVE or AUTOMATED are now accepting bitcoin as a money to bet on their site.
2, In this a casino can accept bitcoin like a credit card did and exchange into chips to play and bet on the game.
3, Casino are gambling place, the owner loves to gamble in anyways, having bitcoin in the casino and get it as a payment for the chip they can use bitcoin another source of income, like this. Ex. 1BTC = 1000US worth of chips while at the end of the day 1050 CHIPS = 1 bitcoin. that's cool for the business right? and the up of market value in the community is a good deal for the casino too.
If the casino management starts accepting bitcoin then they will arrange everything for it. Like if they use like credit cards or something else but one thing is clear that all the gamblers would have bitcoin wallet and will know about bitcoin value. Otherwise they will not be able to use gamble in bitcoins.
For casinos it is also not easy to accept bitcoin because the price is not stable and they may lose their money because of the decreasing price.
