NFT whale Jeffrey Hwang, also known as Machi Big Brother, dumped 1,010 tokens for 11,680 Ether, or $18.6 million, within 48 hours, according to data from Nansen,

The major selling event included 90 Bored Ape Yacht Club NFTs, 191 Mutant Ape Yacht Club NFTs, and 308 Otherdeed NFTs.

Nansen's simian psychometric enhancement technician, Andrew Thurman, spotted the trading activity over two days and said in a discussion on Twitter on February 25 that it's possibly the largest NFT dump ever.

Thurman speculated that Machi Big Brother's swift purchase of 991 NFTs again may have been an attempt to register some profits while simultaneously engaging in one massive wash trade to produce huge disproportionate airdrop profits or transparent market manipulation.

One of the major recipients of the Blur token airdrop from fledgling NFT marketplace Blur is apparently Machi.
