People have spent $1.3m buying virtual cats in the CryptoKitties game

"Launched a few days ago, CryptoKitties is essentially like an digital version of Pokemon cards but based on the Ethereum blockchain. And like most viral sensations that catch on in the tech world, it’s blowing up fast.
Built by Vancouver and San Francisco-based design studio AxiomZen, the game is the latest fad in the world of cryptocurrency and probably soon tech in general.
People are spending a crazy amount of real money on the game. So far about $1.3M has been transacted, with multiple kittens selling for ~50 ETH (around $23,000) and the “genesis” kitten being sold for a record ~246 ETH (around $113,000). This third party site tracks the largest purchases made to date on the game. And like any good viral sensation prices are rising and fluctuating fast. Right now it will cost you about .03 ETH, or $12 to buy the least expensive kitten in the game."
