An Ethereum whale, known for holding 1 million ETH from the ICO, transferred 2,000 ETH (worth approximately $4.63 million) to a multisig address 8 hours ago, potentially indicating an impending sale. The receiving address is reportedly used as a dedicated selling address, with ETH often being moved to OKX shortly after receipt. The funds originated from address 0x2bf...E4087, which frequently interacts with block builders BuilderNet and Titan build.
