What did the most expensive digital work and NFT sell for?

The breakthrough came in 2021, when Christie's auctioned a digital collage by the artist known as Beeple for 69.3 million dollars. It shook received ideas about what could be auctioned at all and set off a boom in NFTs (digital certificates of ownership), which was followed by a steep fall. Even so, it was the moment digital art entered the major auction league.
