Crypto ETPs and Bitcoin ETFs

The structures, and why they are not funds

Crypto ETPs face the same constraint as gold (Chapter 23): a single-asset vehicle cannot be a diversified fund.

• United States: spot bitcoin products are grantor trusts, not '40 Act funds. The trust holds bitcoin with a custodian; your shares represent an interest in the trust. Practical consequences: no fund-level investor protections from the Investment Company Act, and a distinct tax treatment.
• Europe: crypto exposure comes as ETPs/ETNs, typically physically-backed and collateralised, sitting outside UCITS entirely (Chapter 75's taxonomy). Verify collateralisation and segregation, because the range here spans genuinely well-structured products and thinner ones.
• Futures-based products predate the spot versions and hold CME futures rather than coins, importing the roll mechanics of Chapter 23: a structurally different and generally inferior exposure to spot for a buy-and-hold holder.

The identification habit from Chapter 75 applies with force: read whether you own a claim on segregated assets, a collateralised note, or an unsecured promise.

Custody: the thing that actually differentiates products

For a gold ETC, custody is a solved, centuries-old problem. For bitcoin it is the product's substance, and the questions are specific:

• Who is the custodian, and is custody segregated? Are the fund's coins held in identifiable addresses distinct from the custodian's other holdings and its own balance sheet?
• Cold storage and key management. What proportion sits in offline storage, how are keys generated and split, and what are the multi-signature arrangements?
• Custodian concentration. A significant share of US spot bitcoin ETP assets sits with a small number of custodians. That is a genuine concentration risk at the industry level, disclosed and infrequently discussed.
• Proof of holdings and audit. How often are holdings verified, by whom, and is on-chain attestation published?
• Insurance, and precisely what it covers: usually a limited sum against specific loss types, not a blanket guarantee.

An investor comparing two spot products on fee alone, while ignoring these, is optimising the smallest variable in the decision.

The fee war and the flows

The 2024 launch produced an unusually aggressive fee competition: several issuers launched with waivers and headline rates far below the incumbent trust structure, which converted from a closed-end product carrying a much higher fee. Current spot bitcoin ETP fees cluster at roughly 0.15–0.25% (2026), with the converted incumbent still at 1.5%: low by crypto standards, and several times a broad equity index fund's 0.03–0.07%.

Two structural notes:

• The converted incumbent had traded at large discounts and premiums to its holdings for years as a closed-end vehicle: a textbook demonstration of Chapter 4's mechanism, and its conversion to an ETF collapsed that gap almost immediately once creation and redemption began. It is the cleanest real-world illustration in this book of what the arbitrage window actually does.
• Flows were record-breaking, and they came substantially from investors moving out of direct holdings and out of the older structures, as well as from new allocators. Rapid asset gathering is not evidence about the asset's merit; it is evidence about the wrapper's convenience.

The honest investment discussion

Per house rules, both sides, then our view.

The case for a small allocation. Bitcoin has a fixed supply schedule and a fifteen-year track record of surviving repeated declared deaths. Its correlation to equities has been variable and at times low, offering diversification in some periods. The ETP wrapper removes the operational risks that historically caused most retail crypto losses, exchange failures, lost keys, phishing, which is a real reduction in the ways an investor can lose everything for non-market reasons.

The case against. It produces no cash flows, so there is no earnings-based valuation anchor: its price is what the next buyer will pay. Volatility runs several times that of equities, with multiple historical drawdowns exceeding 70–80%. Its correlation with risk assets has often risen exactly when diversification was needed. The regulatory environment remains capable of changing materially. And the "digital gold" thesis is a claim about future adoption rather than an observed property.

Our view, labelled. If held at all, bitcoin belongs in Chapter 61's satellite sleeve at a size where a total loss would be survivable and boring, which for most portfolios that means low single-digit percentages. The wrapper does not make the asset less volatile, and an allocation sized as though it did is the error this chapter exists to prevent. We take no position on whether bitcoin will succeed; we take a firm position on sizing an asset whose distribution of outcomes is this wide.

Beyond bitcoin

Ether products followed spot bitcoin in the US and exist across Europe. The structures are comparable; the asset's characteristics, supply mechanics and regulatory classification differ meaningfully, and the staking question: whether the product can earn staking rewards, and what that does to its risk and tax profile: is a live structural issue worth reading on any specific product.

Basket and altcoin products exist mainly in Europe, where the ETP route permits them. Diversification within an asset class this correlated does less than it appears, and index construction here is young.

"Crypto-adjacent" equity funds hold miners and exchanges. These are equity funds with leveraged operational exposure to crypto prices and to equity markets simultaneously: a different instrument entirely, and one frequently mis-sold as crypto exposure.

A worked example

An investor with a €250,000 portfolio decides on a 2% bitcoin allocation (€5,000) through a European physically-backed ETP.

• Structure check (Chapter 75): physically-backed, collateralised, segregated cold storage, named custodian, monthly attestation. Not a plain unsecured note.
• Sizing check (Chapter 61): at 2%, an 80% drawdown costs €4,000, or 1.6% of the portfolio. Annoying; not plan-altering. Written thesis, no price-based exit, review annually.
• Two years later: the position has fallen 68% at one point and recovered to +40%. Her portfolio-level experience of that round trip was a swing of roughly ±1.5%, which she noticed in the way one notices weather.

The lesson is not about bitcoin's direction, which nobody in this chapter claims to know. It is that correct sizing converted an asset with a 70%-drawdown history into a position she could hold without ever facing a decision, which is precisely what Chapter 61's fence is for.
