I have no idea if casino will ever accept bitcoin as exchange for chips that is used in gambling.
You can realize of course, but casinos are more profitable than cash. And as an alternative is a very good idea, not many will certainly use such a service, but still.
profitable easy and convinient for them if this will happen.its not impossible really,coz some visa cards now for btc.so it will be more easy to use.i just dont know which casino will start this idea.this is very good one if ever.
