If you're a new player you should watch out on this site.

I joined the site a few weeks ago to play the bigbtc, and won it. I was ShitVacuumer. The site didn't pay my winnings, changed the password on my account so I can't log in, and ignores my emails.

They wouldn't dare rip off their regulars, but if you're new and hit a big score they probably see you as an easy mark to fuck over.
