Elon Musk and Katy Perry are among the 15,000 Twitter accounts tokenized by BitClout, a "celebrity network." The site appears to be a scam, according to security firms. In just one week, the site is said to have made $160 million. Bids for an NFT of Jack Dorsey's first tweet topped $2.5 million recently. According to BitCl, the price of the tokens is loosely tied to a given profile's relative popularity.
