In the 10 years since Chris Torres created Nyan Cat, an animated flying cat with a Pop-Tart body leaving a rainbow trail, the meme has been viewed and shared across the web hundreds of millions of times. Nyan Cat was sold to a user identified only by a cryptocurrency wallet number. The price? Roughly $580,000.

Nyan Cat isn’t the most expensive NFT to be sold – A Crypto Punk variant was priced at over $1 million. The NFT-based art market is now surging along with the cryptocurrency markets and is estimated to be worth over $100 million.
