So how much does it cost to play CryptoKitties? The short answer is a little or a lot, depending on what you want.
Cat prices vary from half a dollar to six figures. A cat’s initial selling price is set by the owner. From there it will either gradually descend to a predetermined minimum price or gradually rise to a predetermined maximum price and remain there until the auction ends. The same method applies to putting a cat up for siring. It’s the invisible paw of economics.
Breeding two of your own cats costs a flat rate of 0.008 ETH plus the transaction fee. If you’re breeding one of your Kitties with another player’s cat, you pay the siring price the player set, plus the 0.008 ETH breeding charge and the transaction fee.
So for the most part, the market determines the value of a Kitty. The only Kitty prices we set are for the new Generation 0 cats released every fifteen minutes (until November 2018, when we run out). We sell these cats from our account called Kitty Clock – hence the nickname “Clock” cats. And even then, we don’t really set their price. The starting price of each new Gen 0 Clock Kitty is determined by taking the average selling price of the previous five Clock cats and adding 50%.
So there you have it. You don’t have to be a high roller to enjoy this game. You just need to love cats.
