Twitter's CEO, Jack Dorsey, sold the first tweet he published in 2006 as a non-fungible token or NFT, for over USD 2.9

An NFT is a digital asset that can include a jpeg, video clip, or tweet that runs on the blockchain, a 'digital ledger' that verifies authenticity.

According to United Press International, Dorsey sells a digitally signed version of the tweet, which he uploaded on March 21, 2006, and reads "just prepared my tweet".

The sale was made via Valuables, a digital platform that allows tweets signed by the creator to be bought and sold.

Bridge Oracle CEO Sina Estavi bought the tweet after getting into a bidding war with tech entrepreneur Justin Sun.

"This is not just a tweet! I think years later people will realize the true value of this tweet, like the Mona Lisa painting," Estavi said on Twitter.

Dorsey said on Twitter that he will convert the money made from tweets into Bitcoin and donate it to the charity GiveDirectly, which helps those in Africa who live in poverty.
