(Can someone help me remember about a btc site)

does anyone here know about a btc website that allows trading and investing btc
You can play roulettes on that site.
And there's a section for promo codes.
I still have a promo code for that website and I don't know whether it's still valid or not.
Please help me if anyone knows that site.
It has a purple background. And before entering that site, it will first verify your browser.
It does not send a message to your e-mail when signing up.
And you invest 0.1 to 0.5 btc minimum.
If you know that website please reply to this topic.
And you can ask any questions in case you may have found that site to be sure.

Thanks in advance.
