There is many Casino accept btc.
I suppose he means in real life, I think we may come tot he point where casinos are going to accept bitcoin but when that day comes then that means that bitcoin is already accepted everywhere, since I do not think casinos are going to adopt bitcoin earlier than any other industry.
We just need to wait and watch for this thing to happen. I think this is really a great idea to use bitcoins in casinos and there is no harm in it. In fact, this will increase the market value of bitcoin and will help bitcoin in becoming more popular.
In my opinion, bitcoin can be used just like paper money at almost every corner of the world. We just need to wait for that time when well be having no need of keeping paper money.
