There are many ways such little cash bonuses can be left 'in the blockchain' for people to discover. Imagine a video/podcast which offers various obscured glimpses of a private key's QR code... the first viewer to freeze-frame and stitch-together collects the prize.
Or imagine any other riddles/puzzles with a solution space resistant to brute-force search. The prize for the first solver can be left in the blockchain, with a private key derived from the solution.
After 'easter eggs' (in real life or software), these could be called 'eggcoins'. (I find a prior use of that term related to a geocached souvenir coin.)
