Recent Digital Asset Transfers to Coinbase Prime
BlackRock has been actively transferring substantial amounts of Bitcoin (BTC) and Ethereum (ETH) to its Coinbase Prime account. Recent reports indicate a significant inflow totaling approximately $293.3 million in BTC and ETH. This influx includes an estimated $293.49 million in BTC and $79.83 million in ETH, as observed through blockchain data. The asset manager has executed a series of deposits from its dedicated wallet addresses to the exchange since the beginning of the current month.
💡 The specific rationale behind these ongoing transfers is not yet public. However, discussions within the cryptocurrency community suggest potential reasons such as portfolio rebalancing, custodial adjustments, or even preparation for asset sales. These inflows have occurred consistently for four consecutive days, coinciding with a generally positive momentum in the cryptocurrency market.
Substantial Inflows into Coinbase Prime
In a notable development, BlackRock executed a transfer of approximately $185 million to Coinbase and Prime just yesterday. This recent transaction involved the deposit of 1,198 BTC, valued at around $129.09 million, and 15,121 Ether, worth approximately $56.1 million. Over the span of the last five days, BlackRock has moved more than $1 billion in BTC and Ethereum to Coinbase’s institutional custody platform, attracting considerable attention from market observers and industry participants.

On-chain data from Arkham Intelligence reveals that on October 31, BlackRock transferred 3,496 BTC, valued at approximately $383.9 million, alongside 31,754 ETH, worth around $122 million. Following this, the firm made further deposits on November 1st, amounting to an additional $506 million in combined ETH and BTC value. These outflows from its iShares ETFs represent a significant movement of over $1 billion within a brief five-day period.
Performance of iShares ETFs and Custodial Holdings
The iShares Bitcoin Trust (IBIT) and the iShares Ethereum Trust (ETHA) currently manage a combined total of roughly $100 billion in assets. IBIT ETFs hold approximately $85 billion, while ETHA manages $14 billion. Ether’s share within these trusts stands at 3.3%, and Bitcoin’s share is currently 4.01%.

These extensive transfers are likely a component of standard custodial rebalancing procedures, potentially influenced by investor sentiment and market dynamics. BlackRock appears to be actively managing its significant cryptocurrency positions across its suite of iShares ETFs.
Coinbase currently holds a substantial amount of BlackRock’s digital assets, estimated at approximately $17.6 billion, making it the primary custodian among exchanges for the asset manager. Since March of the previous year, BlackRock’s total withdrawals to various exchanges have reached $17.95 billion. Circle holds an estimated $350 million, and the firm has deposited $3.25 billion since March 2024. Falcon X has also received around $100 million, with the remainder of the funds deposited on the Coinbase exchange.
Market Performance Amid Institutional Movements
Despite the ongoing large-scale transfers, BlackRock has yet to approve a Solana ETF, even as inflows into Grayscale’s GSOL and BSOL on the NYSE continue to rise. Currently, Solana ETFs collectively hold approximately $513 million in assets. SOL ETFs saw inflows of $70 million on Wednesday and close to $220 million over the past month.
Recent analyses suggest that institutional flows from ETFs and corporate treasuries are progressively supplanting retail investor activity in the cryptocurrency market. This shift is underscored by observations that the average cost basis for Bitcoin wallets has reached around $55,900.
💡 Data indicates a decline in smaller Bitcoin holdings since 2023, with many smaller holders redirecting their assets to exchanges like Binance. In early 2023, these smaller holders were depositing approximately 552 BTC daily into Binance. This figure has since decreased to around 92 BTC per day, signaling a trend towards institutional accumulation. The evolving regulatory framework in the U.S., particularly the approval of ETFs, has enabled institutions to gain exposure to crypto assets without direct interaction with exchanges.
At the time of this report, Bitcoin experienced a 4.5% decline on its daily chart, falling below the $104,000 mark. BTC was trading around $101,226. Ethereum, concurrently, saw a 5.5% drop on its daily chart, trading below $3,390.
Final Thoughts
BlackRock’s significant asset movements to Coinbase Prime highlight the increasing institutional engagement with digital assets. While the exact motivations behind these substantial transfers remain a subject of market speculation, they underscore the evolving landscape of cryptocurrency investment and custody. The performance of major cryptocurrencies like Bitcoin and Ethereum is closely monitored in light of these institutional activities.
