ATu tour of Elon Musk. This Tuesday, the multi-billionaire boss of Tesla put on sale a piece of electronic music of his composition for sale on Valuables. At auction, it was ultimately valued at over a million dollars. “I’m selling this song about NFTs as an NFT,” Elon Musk tweeted. Another example, one more, of the excitement around this technology, after the sale by the artist Beeples of a digital image for 69 million dollars. Also after the sale by Chris Torres of his “gif” Nyan Cat, after that of Jack Dorsey, the boss of Twitter, who marketed his first tweet. Also after the American group Kings of Leon released their album in the form of NFT.
