BlackRock-linked wallets deposited 5,212 BTC and 20,000 ETH to Coinbase, a combined transfer worth over $430 million that has drawn immediate attention from on-chain analysts and traders watching for signals of institutional selling pressure. The deposits were flagged by on-chain tracking platform Lookonchain, which identified the wallets as linked to BlackRock. Coinbase, specifically its Coinbase Prime service, was the receiving venue for both the Bitcoin and Ethereum transfers.
