🚨 BlackRock’s Massive Ethereum Transfer: The Facts

BlackRock made headlines on December 16, 2025, by transferring 47,463 ETH (worth about $140 million) to Coinbase Prime. This move, tracked by on-chain analytics and reported by major crypto news outlets, coincided with a sharp 6% drop in Ethereum’s price and significant outflows from US-listed Ethereum ETFs. The event sent ripples through the crypto and automated trading communities, raising questions about institutional motives and the broader impact on liquidity and copy trading strategies.

🔍 Why Did BlackRock Move 47,463 ETH?
