Cryptokitties is like a proof-of-concept of what is possible on Ethereum - imagine kitties replaced with other in-game items etc. Unfortunately, it's also revealed that Ethereum, once again, can't handle high volume.
WHAT A LESSON FOR THE WHOLE CRYPTOWORLD!!!!!!!! I tried the game, as I am just curios, how it actually works. And I need to confes, the POW is not confirmed for the ethereum network. We will see HUGE problems in coming month for the cryptoworld, if there are no more reliable projects in place, which can handle much, much higher transactions also with a LOT lower transaction fees.
