Vitalik Buterin's Ethereum address is reportedly engaging in rapid sell-offs of various meme tokens, according to on-chain data from Arkham. The transactions, occurring several times per minute, suggest the use of automated scripts to liquidate airdropped tokens, with individual sales ranging from tens to hundreds of dollars. This activity mirrors a similar event in 2021 when Buterin sold or donated large volumes of meme tokens, including SHIB, impacting market stability. The current operations have sparked speculation about whether they are manually initiated or fully automated. Given the significant market influence of Buterin's address, meme coin holders are advised to remain vigilant for potential selling pressure.
