Hey did you read their comments before commenting?
I have just highlighted where op said it's for specific casino, meaning this is a casino based site and of course he is right and I can't be sure of running their service. Most times it's important for these upcoming site to use some reputable manager whom that can easily relate with the community to build trust from the forum here because sometimes it's hard for people to easily trust such services.
I did and that was why I quote both of you because of the respond he gave to you. And as it is a casino based services for specific casino. It still looks like a bilateral services. The service sound awkward. "Exchanger for Stake". And this is what in the website.

Though I am not arguing with you since I am not familiar with the service. I am only confused that there is nothing related casino in the site but those who using the service know it better therefore I close my case here. And might probably test the service to know more.
I was also afraid of testing the site because I didn't know how it works, though when I clicked it gives me exactly what you share here but wasn't that cool with it, I think the best is for them to launch a review campaign where people would have to test their services and give feedback to it and of course for them to gain attention and exposure here running a review campaign would be the ideal thing to do.
