No I don't own any.
You can get cheap kitties for about 1 USD. But I am not sure how much money you can generate with these cheap kitties. Breeding also costs some ethereum. I was looking for info on how profitable is if you start from the bottom but I cannot find any clear information anywhere.
Recently there was a vox-docu about crypto kitties. I am not sure if this created a large influx of new users.
I see. I guess in the long run, it probably won't be profitable unless they add more useful/fun features to the game itself. Then again, the internet is cat-crazed, so we can never say for sure. Haha..
