I won't say this site is legit or not. Many people will think it's not profitable to create a zero-edge gambling site, but don't you think it can be good and profitable as well as others? It's probably the last option to bring more users to the site, to bring more traffic to it. The owner won't get profit from their users but still could get profit from the traffic. It could be a perfect marketing strategy anyway.

I'm not sure it will run for long time, but at least they will have many users at first.
