However, Grumpy Cat's owner owns trademarks associated with Grumpy Cat, and it seems she has become aware of the coin. On May 18, she minted an NFT and transferred it to the Grumpy Cat Coin deployer address. The NFT image is a copy of a cease and desist letter representing Grumpy Cat Limited. The letter describes the coin offering as a "blatant and willful infringement of our client's trademark rights", and insists that the coin creators stop all activities related to the coin offering or face legal action. The letter also mentioned that the URL of the project website — grumpycat.fyi
— was a violation of the Anti-Cybersquatting Consumer Protection Act. The project subsequently changed its domain to gccoin.fyi
in an apparent effort to avoid this issue.
Simultaneously, a message addressed to holders of the Grumpy Cat Coin was posted to Grumpy Cat's Twitter account, describing the token as a "desperate, sad attempt to scam unwitting traders" by "SlumDoge Millionaire and their cohorts".
