As concerns about kidnappings and digital hacks mount, notable Bitcoin holders are increasingly exchanging their Bitcoin for shares in BlackRock’s iShares Bitcoin Trust (IBIT). This trend, recently highlighted by the head of BlackRock’s Digital Assets division, Robbie Mitchnick, signifies a shift in how large investors are managing the safety of their cryptocurrency assets.
In an interview with Barron’s, Mitchnick remarked, “Right now, this is the best it’s ever been,” indicating a significant rise in demand for these swaps, primarily driven by the need for enhanced security. Customers are increasingly vocal about their concerns, with the leading motivation cited as “security and peace of mind.”
The process operates through a spot exchange mechanism, where Bitcoin holders transfer their assets to the fund via an intermediary, acquiring newly issued IBIT shares without having to liquidate their coins first. This operation is facilitated by partnerships with firms like Galaxy Digital, Talos, and Virtu, which enforce minimum transaction sizes.
According to Barron’s, BlackRock’s trading volume has reached an estimated $3.6 billion, a figure that may be understated as not all transactions are processed internally. Previously, Mitchnick indicated to Bloomberg that swaps facilitated by IBIT had exceeded $5 billion, marking a substantial increase from $3 billion reported in October 2025.
Mitchnick directly linked the growing trend of swaps to external events influencing investor sentiment. For instance, he stated, “People are motivated to switch all or part of their holdings when they see something happening in the outside world, whether it’s a kidnapping, a ransom, a custody failure.”
Regulatory Development and Expanded Access
A pivotal regulatory change occurred on July 29, 2025, when the SEC approved changes allowing Bitcoin and Ether spot funds to issue and redeem shares based on physical assets, transitioning away from the previous cash-only framework established in January 2024.
Since this regulatory shift, access to IBIT has broadened. The fund initially required a minimum investment of around $30 million, but this has since decreased to between $1 million and $2 million, as reported by Barron’s.
Tax implications also play a critical role in the appeal of these exchanges. Exchanging appreciated Bitcoin for IBIT shares is typically viewed as a transaction that does not trigger capital gains taxes, although individual circumstances can vary as noted by Bloomberg. Additionally, Mitchnick highlighted that estate planning could be more straightforward when managing assets within a private banking framework.
After the exchange, the Bitcoin is securely held by custodians at IBIT, which is affiliated with Coinbase Prime. Mitchnick referred to this system as an “institutional-grade cold storage model,” and as of November 6, the fund held 795,921 BTC, valued at around $60.4 billion.
Analyzing Demand Metrics
While the creation of IBIT shares is counted in the fund’s reported flows, it’s important to note that these transactions do not involve new Bitcoin purchases. Therefore, the reported figures may inflate perceived demand since the underlying coins are simply reclassified under a different investment format.
Conversely, cash flow illustrates a downturn. IBIT contributed to roughly $1.21 billion of the U.S. spot Bitcoin ETF’s net losses amounting to $1.28 billion during the week ending November 6, marking its poorest performance since June, according to data gathered by Pharcyde Investors.
Growing Threats to Self-Custody
Concerns regarding the safety of cryptocurrencies have been intensified by documented incidents of criminal activity. In France, authorities recorded 77 incidents of crypto-related kidnappings, extortions, and home invasions in the early months of 2026, surpassing total cases from the previous year, according to the OCCRP. In one notable case, Ledger’s co-founder was kidnapped along with his spouse, resulting in significant injury.
Similar incidents have been reported in the United States, including a failed initiative in Connecticut aimed at compelling families to relinquish their Bitcoin holdings. Respected Bitcoin security expert Jameson Lopp maintains a public index of assaults against cryptocurrency owners stretching back to 2014, further highlighting the risks associated with self-custody.
This shift towards exchanging Bitcoin for IBIT shares challenges the fundamental ethos of Bitcoin, which was founded on the principle of decentralized monetary control without intermediary involvement. By converting to IBIT, holders relinquish direct custody of their keys, placing trust in BlackRock, its custodians, and the associated market makers.
