In the current quest to blockchain everything, CryptoKitties is a blockchain game where you breed, raise and trade virtual cats.
It’s proved to be a good stress-test of ethereum with a high volume of transactions.
Clones of the game are becoming popular in China, where the government is cracking down on crypto-currencies. Good thing this is only a game about virtual pets, and couldn’t possibly be used as a substitute for money. wink-wink
Gotta catch em all!
