You know Nyan Cat? The legendary GIF, which depicts a gray feline with the body of a Pop-Tart soaring through space (and leaving a rainbow-colored chemtrail), recently sold for $590,000 in an online auction put on by the meme’s original creator. No, GIFs that anyone can find and share for free usually aren’t considered commodities, and yes, this has something to do with the latest crypto-related trend you might have heard of: NFTs. Also hopping on the NFT, or non-fungible token, craze in recent weeks: Lindsay Lohan. Mark Cuban. The band Kings of Leon, which is releasing a new album not in the usual manner but as an NFT. The experimental pop singer Grimes made headlines earlier this week when she made about $6 million selling artwork, much of which featured flying babies, that came in the form of NFTs.
