BlackRock scooped up over $1.8 billion of these cryptocurrencies in a week
BlackRock's Bitcoin (BTC) and Ethereum (ETH) ETFs saw $1.87B in net inflows last week, driven by institutional demand. IBIT attracted $1.33B, while ETHA added $536.8M. The inflows contributed to a strong week for U.S. spot crypto ETFs, with total inflows reaching $2.6B. Bitcoin's rebound and regulatory discussions also boosted investor sentiment.
