Compare U.S.-listed spot Bitcoin and Ether funds by the asset they hold, current prospectus terms, total ownership cost, liquidity and tracking, custody, and—for Ether funds—whether staking is allowed and how it works. A headline fee alone is not enough: trading spreads and premiums or discounts to net asset value (NAV) affect what you actually pay. These funds provide exposure through brokerage-held shares, not direct possession of Bitcoin or Ether.
What is the difference between a Bitcoin ETF and an Ether ETF?
Bitcoin funds hold Bitcoin; Ether funds hold Ether. The assets run on separate networks and are not interchangeable, and owning shares in either fund does not give you the ability to spend, transfer, or use the underlying coins.
“ETF” is common shorthand, but these products are often described as exchange-traded products (ETPs), and legal structures differ. Do not assume every fund is a conventional registered investment company. Check the fund’s current prospectus for its structure, investment objective, and risks.
The regulatory milestones also differ. The SEC approved listing and trading of certain spot Bitcoin ETP shares on January 10, 2024; spot Ether ETP rule changes were approved on May 23, 2024, and Ether products began public trading July 23, 2024, according to an SEC-filed company disclosure. Those actions concern listing and trading, not an endorsement of either asset. The SEC’s January 10, 2024 statement explicitly said it did not approve or endorse Bitcoin. The SEC-filed disclosure reports the Ether trading commencement date.
How do I compare spot Bitcoin and Ether ETFs?
Use the same evaluation points for each fund, and compare figures from the same date and trading conditions. A practical comparison should cover:
- Underlying asset: Bitcoin or Ether, not a diversified basket of cryptoassets.
- Fund structure and terms: investment objective, fee schedule, waiver conditions, and other provisions in the latest prospectus.
- Total cost: annual fund fee plus trading spread, brokerage charges, and any premium or discount to NAV.
- Trading and tracking: volume, median bid-ask spread, market price relative to NAV, benchmark methodology, and tracking against the underlying asset over matching periods.
- Operations and custody: custodian, security and segregation arrangements, insurance scope and exclusions, loss allocation, and procedures for forks or network disruptions.
- Ether staking: whether the specific fund permits it, how rewards are treated, and what related fees and risks apply.
None of these points establishes that Bitcoin or Ether is safer or more likely to perform well. Your choice of fund and asset should reflect your own risk tolerance and financial circumstances.
Which fees and trading costs should I compare?
Annual fund fee and waiver
Start with the fee in the current prospectus or fee schedule. Record whether it is described as an expense ratio, sponsor fee, or another charge, and note any waiver’s conditions and end date. A published fee can change, so compare current documents rather than an old list.
Rank #2
For context, BlackRock’s IBIT product page reported a 0.25% sponsor fee as of September 24, 2026. ARK 21Shares Bitcoin ETF (ARKB) disclosed a 0.21% unitary sponsor fee in an SEC-filed annual report published in 2026. These are fund-specific figures from different products, not a category average or a recommendation. BlackRock’s IBIT product page and ARKB’s SEC-filed annual report provide the cited disclosures.
Trading costs and NAV differences
The annual fee does not capture every cost. When buying or selling, compare the bid-ask spread—the gap between the price available to sell and the price available to buy—and check whether the market price is above or below NAV. Brokerage charges may also apply. These values vary over time and with market conditions; compare funds over the same period rather than treating a single observation as a standing characteristic.
A fund with a lower stated annual fee is not necessarily cheaper to own in practice. The realized cost depends on both the fund’s charges and the conditions under which you trade.
How should I assess liquidity and tracking?
Review trading volume and median bid-ask spread, then compare the fund’s market price with NAV. Also check the benchmark’s construction and how closely the fund’s results tracked the underlying asset over the same dates. These measures can change, so use dated figures and matching periods instead of comparing one fund’s current spread with another fund’s older figure.
There is no issuer-by-issuer ranking here for current liquidity or tracking: the cited materials do not establish a sufficiently current, comparable dataset for those measures. Use each issuer’s disclosures and market data for the dates that matter to you.

Read the prospectus for the individual fund, not just a general explanation of crypto ETPs. Look for who holds the cryptoassets and what happens in unusual events. In particular, check:
- the named custodian or custodians and their responsibilities;
- how assets are held and what security or segregation arrangements are described;
- whether insurance applies, what it covers, and what exclusions or limits apply;
- how the fund allocates losses if an operational or custody problem occurs;
- how it handles forks, network disruptions, and other events affecting the underlying asset; and
- how shares are created and redeemed.
Custody terms are fund-specific. For example, ARKB’s cited 2026 SEC filing names Coinbase Custody as its Bitcoin custodian; that disclosure should not be generalized to other funds.
Creation and redemption mechanics have also changed over time. On July 29, 2025, the SEC announced approval of orders permitting authorized participants to create and redeem crypto ETP shares in kind. The SEC described this as a change from prior products that were limited to in-cash creations and redemptions. The announcement does not establish that every product or participant implements the mechanism identically. Read the SEC’s July 29, 2025 release and consult the current fund prospectus for its process.
Do Ether ETFs stake?
Do not assume that all spot Ether funds either stake or do not stake. Check the exact fund’s current prospectus for whether staking is permitted and, if so, how rewards are treated and what fees apply.

SEC listing approval is not a safety rating or an endorsement of Bitcoin or Ether. In its January 10, 2024 statement, then-chair Gary Gensler said the SEC did not approve or endorse Bitcoin and urged investors to remain cautious about risks associated with Bitcoin and products tied to crypto. The SEC statement is about the Bitcoin listing action; it does not remove the risks of holding fund shares.
Fund shares can make exposure available through a brokerage account, but the investment remains exposed to cryptoasset price risk as well as fund-specific risks. Fidelity describes its FBTC and FETH single-asset crypto ETPs as intended for investors with high risk tolerance, notes that they are highly volatile and could become illiquid, and warns that investors could lose their entire investment. Those statements are Fidelity’s disclosures, not a claim that every fund has identical terms. Review the prospectus for the fund you are considering. Fidelity’s crypto-fund prospectus hub links to its product disclosures.
Quick Recap
A practical comparison checklist
- Identify the exposure. Confirm whether the fund holds Bitcoin or Ether and read its stated investment objective.
- Open the latest prospectus and fee schedule. Note the fund structure, annual fee, any waiver and its conditions or expiry, and material operational risks.
- Compare dated trading data. For the same dates or trading window, examine volume, median bid-ask spread, and market price versus NAV.
- Check benchmark and tracking. Understand how the benchmark is constructed and compare tracking over matching periods.
- Review custody and event handling. Find the named custodian, security and insurance disclosures, loss allocation, and policies for forks or network disruptions.
- For Ether, verify staking terms. Check permission, reward treatment, fees, liquidity constraints, validator exposure, and slashing risk in the current prospectus.
- Judge suitability separately from product mechanics. Consider whether you can tolerate substantial volatility and the possibility of losing your full investment; neither regulatory listing approval nor a lower fee answers that question.
