Activity on the popular cryptocurrency game CryptoKitties has spiked nearly 1,000% overnight to reach 641 ETH volume over the past 24-hours.

Update: It appears that the surge in traffic was caused by one single massive purchase as pointed out by Reddit user u/iloverainbowbelts.

According to DappRadar, the crypto-based game recorded a total of 1,161.79 ETH worth of activity in the past seven days. The 24-hour volume alone represents over 55 percent of CryptoKitties’ total activity for the week.

We initially suspected that the spike may be related to the upcoming milestone, the birth of the one-millionth CryptoKitty virtual character, however, we later uncovered the single big purchase as mentioned above.

We’re getting closer and closer to the birth of the 1,000,000th CryptoKitty! To celebrate this eggciting milestone, 20 Exclusive Kitties will be born between August 29 and the arrival of the 1,000,000th Kitty.

User growth

Although still near all-time lows, active users seem to be forming a slight uptrend in sync with the general crypto market.

Active users peaked at over 14,000 back in December 2017. Since then, it has gradually gone down and stabilized around 300-400 daily users.
