Vitalik dumped the Meme Neiro on Ethereum. Neiro transferred 17.1 billion Neiros (4% of the total) to Vitalik's address, and used this to promote Vitalik as the largest holder. Vitalik then sold the 17.1 billion Neiros in exchange for 44.4 ETH, causing the price of Neiro to plummet by 60%. @EmberCN
