Cryptobounty.com is a "social-based betting game."
Unlike traditional online gaming software, the winners and losers are not chosen by a pseudo-random number generator or a provably fair system. CryptoBounty's main feature is what is called a 'social-based betting game'. As a result, the game has been wildly successful among people who prefer to take their gambling odds in their own hands.
CryptoBounty is one of the largest Bitcoin gambling websites, being launched in Spring 2013, and the unique idea behind was replicated by many casinos. This blend between Bitcoin and the "Ponzi scheme" has proven to be successful ever since the website's inception.
