Twitter founder Jack Dorsey's first ever tweet has been sold for the equivalent of $2.9m (£2.1m) to a Malaysia-based businessman.
The tweet, which said "just setting up my twttr," was first published on March 21, 2006 and was auctioned off by Mr Dorsey for charity.The Malaysia-based buyer Sina Estavi compared the purchase to buying a Mona Lisa painting.
The tweet was bought using the ether cryptocurrency, a rival to bitcoin.
It was sold as a nonfungible token (NFT) on Monday to Mr Estavi, the chief executive of technology firm Bridge Oracle.
An NFT is a unique digital certificate that states who owns a photo, video or other form of online media. Each NFT is unique and acts as a collector's item that can't be duplicated, making them rare by design.
