Twitter CEO Jack Dorsey sells NFT of first-ever tweet for $2.9 million

Twitter CEO Jack Dorsey has sold a non-fungible token (NFT) of the first-ever published tweet for $2.9 million to an investor who goes by the name @sinaEstavi. 

Earlier this month, Dorsey minted the tweet using Cent, an Ethereum-based service that allows users to mint, sell and bid on NFTs of tweets. Dorsey's message, which he sent March 21, 2006, reads "just setting up my twttr."

Dorsey has said he will donate all the proceeds of the auction to GiveDirectly, a non-profit organization that sends cash directly to families living in extreme poverty. It appears after Dorsey received the funds, he transferred them to crypto exchange Kraken.
