Do you need it spelled out for you? OK, let's assume that he hires a lawyer. Where is that lawyer going to file a case? If they file it in a U.S. court, it will be immediately thrown out because overseas companies are not within their jurisdiction. So now he needs to find out where the laws do apply to Betcoin. According to their terms of service, it appears they're operating under the laws of Hong Kong or possibly Curacao. So now he hires a lawyer in Hong Kong to file a court case there. It's going to get thrown out, or maybe he'll get arrested, because he's just admitted to online gambling in Hong Kong, which is strictly illegal. OK, let's find a lawyer in Curacao, because maybe that's where they have an e-gaming license. The reason that businesses get e-gaming licenses in Curacao is because they don't care if your company is reputable or not and won't prosecute you as long as you give them money for a license. Now what?

If he had been playing in a B&M casino in Las Vegas, he would have some legal avenues to pursue, but he wasn't. Obviously, the issue with playing on overseas casinos like Betcoin with sketchy or no licensing is that if something like this happens, you have no legal recourse, as demonstrated in jasonort's situation.
