Look at the data behind the sudden rise and fall of CryptoKitties

CryptoKitties, one of the first games built on Ethereum, arguably brought NFTs (non-fungible tokens) to mainstream attention. But now, more than a year later, the game has faded into obsolescence. 

CryptoKitties boomed in popularity in December 2017 — at the peak of the crypto bubble. The game consumed around 15% of Ethereum’s traffic and drove the median transaction fees to upwards of $3, which is more than 100 times higher than the current fees.
