For selfish AP reasons, I have always been on the fence about wanting too many online regulated casinos if theres a risk of shutting down the places "licensed" in Curacao and God knows where else.
Short-term it will definitely present more opportunities, especially for those that won't step foot into the unregulated online casino scene. Eventually, online casinos will tighten up once they Corner the market. Promotions will tighten up greatly once all the advantage players start descending and more coming out of the woodwork. One a good aspect about having online casinos regulated and license is the fact that you'll probably almost always get paid. As we all know that can be a problem with the offshore joints. Your choices will be No Doubt be limited. Right now there's probably about two thousand different choices online, unfortunately, there is only around 300 that allow players from the United States, give or take a hundred, some either don't care or they don't really say. There's also other ways to get around that.
With the online regulating casinos come strict laws that you could be prosecuted for violating. Of when it comes to the offshore places, I'm not sure who the hell's going to come after you. Kind of like card counting, you might be breaking rules, but not laws.
If you're in the affiliate game it might be pretty hard for the small guy to get a gig being an affiliate and I'm sure they're not going to be giving great deals.
