This app (when installed on an iPhone 5s) was going for $100,000 on ebay just a week ago.
"Flappy Bird crazy time comes after the game’s developer, Dong Nguyen, a 29-year-old from Vietnam, announced that he had decided to
pull the game from the iTunes App Store and Google Play. Nguyen was reportedly raking in some $50,000 per day from advertising revenue from the free mobile game, which reached the top of the App Store charts and was downloaded millions of times.
While Nguyen considers the game “a success,” he
explained on Twitter that the game “ruins his simple life,” which appears to be the reason he took the game down."
