BlackRock has significantly increased its cryptocurrency holdings, purchasing nearly $1 billion in Bitcoin and Ethereum over the past week. The majority of this investment was directed towards Bitcoin, with BlackRock's iShares Bitcoin Trust recording approximately $732.6 million in net inflows over five trading days. Key accumulation days included April 20 and April 22, with inflows of $256 million and $246.9 million, respectively. Ethereum also saw substantial investment, albeit on a smaller scale, with BlackRock's Ethereum ETF attracting around $199 million in net inflows during the same period. April 20 marked the highest single-day inflow for Ethereum, reaching $89.3 million. This surge in institutional investment reflects a broader trend of increasing demand for cryptocurrency ETFs as the market shows signs of recovery.
