BlackRock has been actively trading significant amounts of cryptocurrencies, particularly Bitcoin (BTC) and Ethereum (ETH), over the past week. The asset manager initially sold large quantities of BTC, with transactions totaling over $836 million on August 26 and multiple sales exceeding $190 million on August 25. Concurrently, BlackRock has been aggressively purchasing Ethereum, with notable buys including $314.9 million worth of ETH on August 25 and $233.6 million on August 21. The firm also made several smaller purchases of BTC, including a $63.4 million buy on August 26. Overall, BlackRock's trading activity indicates a strategic accumulation of Ethereum while intermittently selling Bitcoin. These moves reflect a growing institutional interest in Ethereum as a core digital asset amid volatile market conditions. Other institutional investors, such as Fidelity, have also participated in large Ethereum purchases totaling $337.7 million. The substantial volume and timing of these trades suggest a nuanced approach by BlackRock to balance its crypto portfolio between BTC and ETH.
