Bitcoin ETF custody centralizes authority, leading to significant repercussions from a single operational mishap.

When markets are inactive and Bitcoin is fluctuating, the custody agreement determines who is authorized to act.

A spot Bitcoin ETF resolved a challenging issue for finance. Bitcoin previously existed as software, keys, and operational responsibility. The ETF transformed it into a ticker that appears alongside all other tickers.

This convenience came with a structural compromise. Most ETF purchasers gain exposure while another party retains authority. Gannett Trust presents this as a conscious decision between convenience and control, grounded in what Bitcoin explicitly delineates.

Ownership resides in keys and authorization, rather than in a declaration indicating economic exposure. Traditional markets obscure these distinctions. Bitcoin does not, which is why the documentation may seem familiar while authority is held elsewhere.

This separation once felt philosophical. It became operational as Bitcoin transitioned from trading to treasuries and long-term portfolios, where risks encompass governance, key-person reliance, operational failures, and continuity planning. Thus, when issues arise, who possesses authority?

The ETF generates exposure, while custody establishes power

When you acquire a spot Bitcoin ETF, you are purchasing shares in a trust, and the trust holds Bitcoin via a custodian.

In the case of stocks and bonds, the operational layer appears abstract because the legal and technical frameworks have developed in tandem. With Bitcoin, the technical framework is the ownership framework, with keys enabling movement and authorization establishing control.

SEC filings clarify the structure. One spot Bitcoin trust prospectus indicates that “each Share represents a fractional undivided beneficial interest in the net assets of the Trust,” while “the assets of the Trust consist primarily of bitcoin held by the Bitcoin Custodian on behalf of the Trust.” This statement encapsulates the entire issue. Shareholders possess shares, the trust owns bitcoin, and the custodian safeguards it.

A recent SEC filing for another bitcoin trust employs the same fundamental architecture, again detailing bitcoin held by the custodian on behalf of the trust and shares as beneficial interests in the trust’s net assets. The phrasing may differ by issuer, but the structure remains consistent.

This is where power consolidates. “On behalf of the trust” signifies a custody relationship, and custody centralizes operational authority. It also concentrates points of failure, as access control, signing policies, operational resilience, business continuity, and legal processes reside within that relationship. Retail shareholders cannot redeem shares for bitcoin in the same manner that a native holder can freely move bitcoin.

Bitcoin’s balance-sheet era transforms keys into governance

Gannett Trust’s report elucidates why this is a pressing issue currently. Bitcoin is shifting from speculative positioning to strategic ownership, with durability, control, and administrative rigor becoming core considerations alongside liquidity.

In this context, due diligence takes on a new form. Rather than concentrating solely on execution, the focus shifts to governance. Who holds authority, how is it exercised, and how does it persist over time? The report highlights the risk categories that gain significance when assets transition from trading accounts to balance sheets: governance failures, ambiguous decision rights, operational breakdowns, and continuity planning.

This list will resonate with anyone familiar with traditional finance. Bitcoin introduces a unique aspect because the authority layer is technical. If an organization loses the capacity to authorize movement, it literally loses control.

ETFs appear to provide a workaround. For many investors, the ETF shifts the custody issue into a regulated framework. The custody contract effectively becomes the governance contract. The sponsor, trustee, custodian, prime execution agent, and authorized participants become part of the control framework, even though the buyer perceives they have acquired a straightforward Bitcoin position.

Gannett Trust characterizes the trade as a decision between convenience and control. Derivative exposure provides simplicity and operational familiarity. Native ownership offers control and sovereignty, necessitating purpose-built governance and administration.

As Bitcoin becomes integrated into long-term structures, the persistent question is who holds authority, how it is exercised, and how it endures over time.

This is a custody question masquerading as a portfolio question.

The scale indicates the direction of the default

The structural argument would hold little weight if ETFs remained small. With over $54 billion invested in spot Bitcoin ETFs as of Feb. 25, it has become integral to market infrastructure. Approximately 1.47 million BTC are in spot Bitcoin ETFs, with an additional 3.27 million BTC held on exchanges.

These figures serve dual purposes. They illustrate a new class of holders becoming substantial enough to influence liquidity and market microstructure, and they demonstrate that paper rails are becoming the primary on-ramp. When millions of coins are contained within institutional wrappers, new participants first perceive Bitcoin as an instrument rather than an asset in a wallet.

This distinction is significant because learning influences behavior. A buyer who understands Bitcoin through ETFs views it as a market-hours asset, a brokerage asset, a compliance asset, and a statement asset. Conversely, a buyer who learns Bitcoin through native custody perceives it as a bearer asset with continuous settlement. Both groups may hold Bitcoin long, but they occupy different power dynamics.

The ETF share class can expand while the number of individuals controlling keys remains static. Over time, this may resemble a class system: exposure holders versus owners.

Gannett’s report considers the divide as structural rather than semantic, rooted in Bitcoin’s design. Once this is acknowledged, the next question becomes practical. What potential issues could arise within the intermediary stack, and what implications do they have for the buyer in each scenario?

The plumbing risk: concentration and the trading window

Begin with custody concentration. The spot Bitcoin ETF market rapidly converged on a pattern: a limited number of major products, a few custodial arrangements, and one crypto-native custodian appearing repeatedly. Coinbase served as the custodian for eight of the 11 spot Bitcoin ETF listings at launch.

Concentration can yield efficiencies through standardized processes, economies of scale, consistent controls, and simplified interfaces for asset managers. However, it also creates a single cluster where operational resilience and governance become system-wide concerns.

Next is the trading window. Spot bitcoin ETF investors are restricted by market hours for trading, while bitcoin trades continuously across various venues and jurisdictions. If Bitcoin experiences a gap on a Saturday, the ETF position cannot adjust until the market opens. Those who can move the underlying asset are situated within the custody stack, while everyone else remains in the share market awaiting its reopening.

This disparity prompts an uncomfortable yet clarifying question. Which market do you genuinely own exposure to if you possess ETFs: the continuous Bitcoin market or the listed share market that references Bitcoin?

When something fails, authority appears different depending on the lane

A helpful approach to understanding the two lanes is to concentrate on authority paths, meaning the routes through which decisions and actions occur when conditions change rapidly.

In native ownership, the authority path traverses the keys. Who can sign, under what circumstances, with what approvals, who can rotate keys, where backups are stored, and how continuity is maintained across life events and organizational transitions. These specifics constitute the governance layer.

In the ETF lane, the authority path flows through institutional roles: sponsor, trustee, custodian, authorized participants, listing venue, and broker. The investor’s decisions are primarily financial: buy, sell, size, rebalance. They gain simplicity and accept that authority resides within a framework of contracts and counterparties.

People often perceive ETF convenience as an upgrade to the user interface. In reality, it represents a reallocation of operational agency. It may seem like a beneficial feature, but it can become a layer of fragility once ETF holdings grow sufficiently large that custody and operational practices become systemically relevant.

A spot Bitcoin trade can accommodate some disorder. A balance-sheet asset necessitates robust governance. The ETF buyer delegates governance to institutions, while the native holder incorporates it into key policies and procedures. Neither lane is inherently superior. The risk lies in misinterpreting the lane you have selected.

The new Bitcoin class system: exposure holders and owners

Spot Bitcoin ETFs have thrived because they made Bitcoin comprehensible to the largest capital pools globally. They transformed keys into a fee line item and custody into a service relationship, providing a version of Bitcoin that fits within the conventional wealth framework.

The resulting divide is one of the most significant structural characteristics of Bitcoin’s institutional era. Exposure and ownership are distinctly separated, and allocators face a choice between convenience and control. Bitcoin is among the few assets where ownership is a technical reality, which brings the authority question to the forefront.

The scale clarifies the direction. Approximately $54 billion worth of BTC is held in ETFs, indicating a market that favors paper rails even when the underlying asset was designed around bearer control. The market can accommodate this, and the buyer can accept it. The failure mode arises from mislabeling it as ownership when it is delegated authority.
