According to on-chain analyst Aunt Ai (@ai 9684 xtpa), a whale who received 1 million ETH during the Ethereum ICO withdrew 13,600 ETH (approximately $47.01 million) from the Kraken exchange between July 14 and August 4 at an average price of $3,457. This was the first time in two years that this address had withdrawn ETH from an exchange rather than sold it. Subsequently, between August 18 and 28, the investor sold 5,300 ETH on-chain at an average price of $4,152, earning $3.68 million in profits from this swing trade.
