The first tweet is being offered for sale by Twitter CEO Jack Dorsey.
With the highest bid being $2.5 million, as reported by CNBC.
Jack Dorsey seems to be selling the first tweet as a non-fungible token, or NFT.
The Twitter CEO posted a link to a website called “Valuables”, where his March 21, 2006 tweet “just setting up my twttr” was up for auction.
According to the website, the highest bid was $2.5 million from Sina Estavi, CEO of Bridge Oracle.
These assets are registered on a blockchain, which is a distributed database similar to the networks that support bitcoin and other cryptocurrencies.
However, unlike other currencies, one NFT cannot be exchanged for another in the same way as dollars or other assets can.
Each NFT is one-of-a-kind and serves as a collectible object that cannot be duplicated, making them extremely rare.
Crypto collectibles have become extremely popular in recent months, with everything from musicians to rock bands minting their work.
In an online auction last month, a digital rendition of the Nyan Cat meme from 2011 sold for nearly $600,000.
Some buyers of NFTs believe that, thanks to blockchain, they will be able to prove ownership of a virtual object.
