According to @ai_9684xtpa, an ancient Ethereum whale who initially held 150,000 ETH from the ICO has transferred 2990 ETH (worth $7.97 million) to Kraken nine hours ago, potentially for selling. Over the past six days, this whale has moved a total of 15,000 ETH (worth $39.33 million) to exchanges, completing the liquidation of this address's ETH holdings. Four other addresses still hold a total of 60,000 ETH.
