Twitter celebrates its 20th anniversary with its first tweet, and its NFT was sold for $2.9 million.

CoinFeed reported on March 22nd, citing cnBeta, that Twitter co-founder Jack Dorsey's first tweet, "just setting up my twttr," posted on March 21, 2006, marks its 20th anniversary. This tweet has been archived at the Computer History Museum and holds a separate Guinness World Record; its NFT version sold for approximately $2.9 million in 2021, further solidifying its status as an internet historical artifact. Since then, Twitter has undergone several major transformations: Elon Musk acquired it and renamed it X, which was subsequently merged into xAI, and xAI later became part of SpaceX.
