According to @rovercrc, BlackRock’s ETH holdings increased 65% over the past 30 days while BTC holdings rose 4%, implying ETH accumulation is 15x faster than BTC and signaling an ongoing ETH rotation at the world’s biggest asset manager (source: @rovercrc on X, Aug 16, 2025). For trading, the reported tilt provides a reference for monitoring ETH/BTC relative momentum and institutional allocation trends using these holdings changes as a signal (source: @rovercrc on X, Aug 16, 2025).

According to Crypto Rover, BlackRock currently holds $4 billion worth of Ethereum (ETH), signaling a significant move by traditional finance into the crypto market (source: Crypto Rover, Twitter, June 3, 2025). This large-scale investment by one of the world's largest asset managers is likely to increase institutional confidence in ETH and could drive further inflows from other major investors. Traders should monitor potential impacts on ETH price volatility and liquidity, as well as possible shifts in market dominance between Bitcoin and Ethereum.

According to @OnChainCollege, BlackRock now controls almost 2% of the total Ethereum (ETH) supply as a result of ongoing ETF inflows. This substantial accumulation signals heightened institutional interest and could tighten ETH liquidity on major exchanges. Traders should monitor ETF flow data and BlackRock's holdings closely, as increased institutional ownership may impact price volatility and longer-term supply-demand dynamics (source: @OnChainCollege on Twitter, June 2024).
