Who Makes Money When You Own a Bitcoin ETF?
Direct answer: When you own a spot Bitcoin ETF, the ETF sponsor earns an annual management fee on your assets. A Bitcoin custodian holds the underlying Bitcoin on behalf of the ETF trust and earns custody fees. When you trade the ETF shares, your broker, the market maker, the exchange, and the clearinghouse each earn. The ETF structure adds a cost layer on top of the underlying Bitcoin price movement.
The spot Bitcoin ETF structure
Spot Bitcoin ETFs, approved by the SEC for U.S. listing in January 2024, hold actual Bitcoin in custody. Each share of a spot Bitcoin ETF represents a fractional ownership of Bitcoin held in a regulated trust. Unlike futures-based Bitcoin ETFs (which hold Bitcoin futures contracts and must periodically roll those contracts), spot ETFs track the Bitcoin price directly, minus fees and expenses.
The trust structure means that shareholders in a Bitcoin ETF do not own Bitcoin directly. They own shares in a trust that owns Bitcoin. This distinction matters for several reasons: the trust structure inserts the ETF sponsor and custodian between the investor and the underlying asset, each charging for their services.
The ETF sponsor (management fee)
The ETF sponsor, whether BlackRock (iShares Bitcoin Trust, ticker IBIT), Fidelity (Wise Origin Bitcoin Fund, FBTC), Invesco Galaxy (BTCO), ARK 21Shares (ARKB), or others, earns an annual management fee on assets. This fee is deducted from the trust's Bitcoin holdings by selling a small fraction of the trust's Bitcoin holdings each day, reducing the amount of Bitcoin each share represents over time.
Major spot Bitcoin ETF sponsors priced fees at 0.20% to 0.50% annually after initial waiver periods, which were used aggressively to attract first-mover AUM. At 0.25% on $10 billion in Bitcoin, the sponsor earns $25 million annually in gross management fees. BlackRock's IBIT grew to over $20 billion in AUM within months of launch, generating substantial fee revenue for BlackRock at its stated 0.25% post-waiver rate.
These fees are meaningfully higher than the expense ratios on commodity index equity ETFs (which are near zero) but in line with or below the fees on many alternative asset ETFs and far below the fees on actively managed crypto funds (which historically charged 2% or more).
The Bitcoin custodian
The most structurally distinct participant in the Bitcoin ETF ecosystem is the cryptocurrency custodian. Unlike an equity ETF whose underlying securities are held in standard brokerage form through the DTC, a Bitcoin ETF must hold Bitcoin in secure offline storage (cold storage) to protect against theft or hacking.
Coinbase Custody Trust Company, a regulated subsidiary of Coinbase Global (COIN), serves as the Bitcoin custodian for several major spot Bitcoin ETFs including BlackRock's IBIT and Fidelity's FBTC (Fidelity uses its own affiliate, Fidelity Digital Assets, for custody). Coinbase Custody holds the Bitcoin in wallets where the private keys are stored offline, segregated per client.
Custody fees for cryptocurrency are higher than for traditional securities, reflecting the specialized security infrastructure required. These fees are typically included within the fund's overall expense ratio rather than billed separately, but they reduce what the ETF sponsor retains as profit margin from the gross management fee.
Trade-execution costs when you buy or sell Bitcoin ETF shares
When you trade Bitcoin ETF shares on a stock exchange, the same parties that earn from any ETF trade earn here too:
- Your broker earns from payment for order flow, net interest income on your cash balance, or account fees.
- The market maker earns the bid-ask spread on the Bitcoin ETF shares.
- The exchange earns transaction fees.
- The clearinghouse earns clearing fees.
Bitcoin ETF shares trade in large volumes on major U.S. exchanges, so bid-ask spreads are typically tight, similar to a liquid equity ETF. This is a structural improvement over the Bitcoin futures ETFs launched earlier, whose creation/redemption dynamics created more spread volatility.
Bitcoin ETF costs compared to direct Bitcoin ownership
Owning Bitcoin directly involves a different set of costs and tradeoffs:
| Cost type | Spot Bitcoin ETF | Direct Bitcoin ownership |
|---|---|---|
| Ongoing annual cost | Expense ratio (0.20%+ annually) | Hardware wallet: one-time cost (~$50 to $200). Exchange custody: often 0% but may earn from spread |
| Buy/sell transaction cost | Brokerage spread (tight for liquid ETFs) | Exchange fee (0.1% to 1.5% per trade depending on platform) |
| Security responsibility | Custodian holds keys; trust structure | Owner holds keys (self-custody) or exchange holds (counterparty risk) |
| Settlement and brokerage integration | Standard brokerage settlement (T+1) | Blockchain confirmation (minutes to hours depending on network) |
| Regulatory and tax reporting | 1099-B from broker; standard securities treatment | Complex crypto tax reporting; each transaction is a taxable event |
For a long-term holder, the ETF's annual fee compounds over time and represents a persistent drag on returns relative to direct ownership. For an investor who holds in a tax-advantaged retirement account and values the simplicity of standard brokerage integration, the fee may be worth the convenience.
The creation/redemption mechanism for Bitcoin ETFs
Bitcoin spot ETFs use cash creation and redemption rather than in-kind creation. This is because Bitcoin cannot be delivered through the same electronic settlement system (DTC) used for traditional securities. When an authorized participant creates new shares, it delivers cash to the trust, and the trust's Bitcoin custodian uses that cash to purchase Bitcoin on the market.
Cash creation means the fund itself is a buyer and seller in the Bitcoin market when shares are created or redeemed. This creates a small but real market impact from large ETF flows, which is different from the in-kind ETF structure where the fund does not transact in its own underlying when APs create/redeem.
Who does not earn from your Bitcoin ETF ownership
Bitcoin miners do not earn from your ETF ownership. The ETF's trust already holds its Bitcoin; each share you own represents a claim on existing Bitcoin, not newly mined Bitcoin. Miners earn from block rewards and transaction fees when new transactions are included in the blockchain, not from changes in ownership of existing Bitcoin shares.
Crypto exchanges (Coinbase, Binance, Kraken) earn from transaction fees when Bitcoin is bought or sold. The trust's custodian may use a crypto exchange to purchase or sell Bitcoin when processing cash creations and redemptions, which would generate exchange fee revenue at those moments. But as a holder of static Bitcoin ETF shares, you are not generating ongoing exchange fee revenue.
Frequently asked questions
Who makes money when you own a Bitcoin ETF?
When you own a spot Bitcoin ETF, the ETF sponsor earns an annual management fee on your assets. A Bitcoin custodian holds the underlying Bitcoin on behalf of the ETF trust and earns custody fees. When you trade the ETF shares, your broker, the market maker, the exchange, and the clearinghouse each earn. The ETF structure adds a cost layer on top of the underlying Bitcoin price movement.
What are the expense ratios of major spot Bitcoin ETFs?
Spot Bitcoin ETFs launched in the U.S. in January 2024 with a range of expense ratios. Most sponsors priced fees between 0.20% and 0.50% annually after waiver periods. BlackRock's iShares Bitcoin Trust (IBIT) settled at 0.25% after an initial waiver period. Fidelity's Wise Origin Bitcoin Fund (FBTC) settled at 0.25%. ARK 21Shares Bitcoin ETF (ARKB) and Invesco Galaxy Bitcoin ETF (BTCO) competed similarly. Fee waivers were common in the first months after launch to attract initial AUM. Verify with current fund prospectus disclosures before investing as fee structures may have changed.
What is the Bitcoin custodian's role in a spot Bitcoin ETF?
The Bitcoin custodian holds the actual Bitcoin on behalf of the ETF trust, keeping it in secure cold storage (offline wallets not connected to the internet). Coinbase Custody (a regulated subsidiary of Coinbase Global) serves as custodian for several major spot Bitcoin ETFs including IBIT. The custodian charges a custody fee for this service, which is typically included within the fund's overall expense ratio rather than billed separately to investors.
Is it cheaper to own Bitcoin directly or through a Bitcoin ETF?
The answer depends on how you calculate direct ownership costs. A spot Bitcoin ETF charges an ongoing expense ratio (typically 0.20% to 0.50% annually) plus trading costs when you buy or sell ETF shares. Direct Bitcoin ownership through a crypto exchange involves trading fees (often 0.1% to 1.5% per transaction) and possibly ongoing custody costs. For long-term holders, the ETF's annual fee can add up; for frequent traders, exchange fees may dominate. The ETF adds settlement convenience, brokerage account integration, and regulated custody.
Does a spot Bitcoin ETF hold actual Bitcoin?
Yes. A spot Bitcoin ETF holds actual Bitcoin in custody, unlike earlier Bitcoin futures ETFs (like BITO, launched in 2021) that held Bitcoin futures contracts rather than Bitcoin itself. Holding futures introduces roll costs and tracking error relative to the spot Bitcoin price. Spot ETFs directly track the Bitcoin price minus the expense ratio and custody fees, making them a more direct exposure vehicle.
