Ethereum co-founder Vitalik Buterin has sold 493 ETH, potentially linked to his recent donation plan. On-chain analyst Aiye reported that Buterin transferred 16,384 ETH, valued at approximately $44.75 million, from his personal address to a multisignature address four days ago. The sale of 493 ETH commenced today, aligning with Buterin's January 30 announcement to support open-source software and hardware development.
