Incidentally, I used Google webmaster tools to remove the site from the search engine results.....Up until then it was ALWAYS on the first page (top 10) when most bitcoin betting related phrases were used in a search.
Valuate.com put the value of the domain at $60......I would take half that amount in bitcoin.
Why did you spoil that google positioning if you planned to sell that domain it doesn't make sense.
SEO of that caliber always helps the site to be more valuable, no matter what content is currently on it.
