The Spectacular Collapse of CryptoKitties

CryptoKitties, the early Ethereum blockchain game, peaked in late 2017 and has declined sharply since, and the article attributes this to breeding that saturated the market and to high gas fees. Daily sales peaked in early December 2017 and by March 2018 averaged under 3,000, while today the game is lucky to break 100 sales a day. Xiaofan Liu of City University of Hong Kong says the breeding mechanism diluted rarity, and Mihai Vicol of Newzoo says gas fees reached $100 to $200 per transaction. Bryce Bladon, a founding member of the team, agrees the breeding criticism is valid.
