An audience that cannot be bought as a list
Zano is a privacy-focused cryptocurrency. To grow real-world usage, the project wanted to be accepted as a payment and deposit option on online gambling platforms, with the strongest fit among privacy-coin friendly and no-KYC operators. That audience is valuable and notoriously hard to reach. There is no clean list to buy.
Three things make this market resistant to normal prospecting. Coverage: operators are scattered across gambling-specific domain extensions but plenty of the best sit on plain .com, .io or .gg, so a single source misses most of them. Qualification: a gambling domain is not proof of an active site, and an active site is not proof it takes crypto, both have to be verified at the page level across thousands of sites. Contactability: even once confirmed, most operators block scrapers and publish no contact data. closed:in's brief was not to run a campaign, it was to engineer the targeting layer itself and hand it over for Zano to run.
