Has anyone considered this yet? A in-real-life Bitcoin casino with Bitcoin machines where you can scan QR codes on them and deposit your BTC on there and start playing. I think it would be pretty cool, no longer would have to deal with annoying coins which are always dirty and are pretty disgusting to touch specially while you are eating/drinking while you play. The machines would be able to do things normal machines can't do, and stealing funds from the casino would be next to impossible since there are no physical money to stuff, it's all digital and encrypted.
Who will be the first person to start a successful physical Bitcoin business?
Theres certainly possibilities of it happening and it might happen at some point but not yet. They would need to use a system that doesnt need confirmations when you deposit and it would help if the deposit was "casino wide" so you would not need to deposit for every different game. Not sure how to achieve this in way that makes sense, but someone will figure it out.
