This article shows why I personally would not be investing in a casino -
http://www.coindesk.com/bitcoin-poker-site-operator-to-pay-25000-fine/Just dodging regulation to run the site if done wrong you get in big trouble. It's not a small deal operating a casino if you are operating in a place with laws. Most try to go to places to dodge these laws on hosting.
Satoshidice doesnt allow US based gamblers, and to my knowledge there arent any strict gambling laws elsewhere, especially not where I live.
But that article you put out just proves the opposite. That guy got fined because the big oligarch casinos dont like competition and they used regulation to kick them out.
So with your example you just proved how corrupt regulation is and how evil political tool can it be ( ban of BTC in Taiwan rings a bell?)
You know some people are using VPN's and Proxy's to get through to satoshidice. But blocking US I would agree gives them better chance of not being taken down.
How are the laws in Europe and China on gambling sites online? Just curious if anyone lives there and knows if legal/illegal.
What country are you in realbitcoin is I can ask? I do admit I am more familiar with us, many other countries I don't know as well I am not a lawyer.
