Crypto ETFs explained: holdings, fees and how they work

Short answer

A spot bitcoin or ether ETF gives you shares in a trust. A custodian holds the coins, not you. Bitcoin fund fees cited here run from 0.15% to 1.50% a year. The US SEC approved 11 spot bitcoin ETPs on Jan. 10, 2024. Large broker-dealers called authorized participants create and redeem shares, which keeps the share price close to the value of the coins the trust holds.

What happened The SEC approved 11 spot bitcoin ETPs on Jan. 10, 2024. Spot ether ETFs began trading on July 23, 2024.
Why it matters You can get bitcoin or ether exposure in an ordinary brokerage account. These trusts are not registered under the Investment Company Act of 1940, so they lack the protections of mutual funds and '40 Act ETFs.
What you pay Sponsor fees cited here run from 0.15% (Grayscale Bitcoin Mini Trust) to 1.50% (GBTC).
What to watch Fee waivers such as ETHB's 0.12% rate, and new funds listed under the 2025 generic standards.

What do you actually own when you buy a spot crypto ETF?

A spot crypto ETF is a trust that buys and holds the underlying asset itself. The coins sit with a custodian. BlackRock's iShares Staked Ethereum Trust ETF (ETHB), a staking fund, names Coinbase as custodian, according to its product brief. You own shares in the trust. You cannot withdraw the coins or send them to a wallet.

That is different from the bitcoin futures ETFs that came first in the US. Those funds held CME futures contracts rather than bitcoin, according to law firm Proskauer.

Issuers publish holdings daily. The iShares Bitcoin Trust (IBIT) page listed a 'Basket Bitcoin Amount' of 22.64 as of Oct. 23, 2026. That figure is the amount of bitcoin tied to one creation basket of shares. You will find this figure, along with net assets and the sponsor fee, on the fund's issuer page. It changes daily.

One legal point matters for buyers. Spot crypto trusts such as ETHB are not registered under the Investment Company Act of 1940, BlackRock's brief says. They do not have the same protections as mutual funds or '40 Act ETFs.

The share price moves with the price of the coins the trust holds, so you can lose money if that price falls. The ETF wrapper does not reduce that risk.

You own: shares of a trust listed on a stock exchange
The trust owns: bitcoin, ether or another crypto asset, held by a custodian
You do not own: the coins directly or the private keys

How did the US go from bitcoin-only funds to altcoin ETFs?

The spot bitcoin approval followed a D.C. Circuit ruling against the SEC's rejection of Grayscale's application to convert its bitcoin trust, according to Proskauer. On Jan. 10, 2024, the SEC approved 11 spot bitcoin ETPs in a single order, including iShares Bitcoin Trust, Fidelity Wise Origin Bitcoin Fund and Grayscale Bitcoin Trust.

Then-Chair Gary Gensler said the approval was limited to products holding bitcoin and that the SEC 'did not approve or endorse bitcoin.' Ether followed. The SEC approved exchange rule changes on May 23, 2024, and the funds began trading on July 23, 2024, according to Decrypt.

The bigger shift came in 2025. In July, the SEC allowed in-kind creations and redemptions. In September, it approved generic listing standards. Exchanges could then list qualifying commodity-based trust shares, including crypto, without a separate Section 19(b) rule filing for each fund. That cut out a product-by-product approval step, and solana and XRP funds launched within weeks.

Key US spot crypto ETF milestones, per the cited sources

What do crypto ETFs cost?

The main cost is the sponsor fee, also called the expense ratio. It comes out of fund assets, so you never see a bill. A 0.25% fee costs $25 a year per $10,000 held. A 1.50% fee costs $150.

Grayscale Bitcoin Trust stands out. It charges 1.50%, cut from 2% when it converted to a spot ETF, according to ETF Database. That is the highest fee in the original group. Grayscale also launched a cheaper Bitcoin Mini Trust on July 31, 2024, at 0.15%, seeded with 10% of GBTC's assets, Bloomberg reported.

Waivers can lower the fee for a period. ETHB's sponsor fee is 0.25%, but BlackRock waives it to 0.12% on the first $2.5 billion for 12 months from March 12, 2026.

The sponsor fee is not the only cost. You also pay the bid-ask spread when you trade, plus any broker commission. If you buy when shares trade above the value of the trust's holdings, or sell when they trade below it, you lose the difference. Issuer pages show the fee, net assets and daily holdings, so check the fund page before you trade.

Fidelity Wise Origin Bitcoin Fund	FBTC	0.25%	ETF Database

How do creations and redemptions keep the price in line?

ETF shares trade on an exchange all day, so their price can drift from the value of the coins in the trust. Large broker-dealers called authorized participants close that gap. When shares trade above the holdings' value, they create new shares by delivering assets to the trust. When shares trade below, they hand shares back and redeem them. That arbitrage pulls the share price toward the value of the holdings.

The first spot bitcoin ETPs worked in cash only, Proskauer noted. The issuer had to buy or sell bitcoin on the open market whenever shares were created or redeemed. SEC Commissioner Mark Uyeda argued that this added costs and slippage. Since July 29, 2025, authorized participants can also deliver or receive the crypto itself rather than cash.

The same July 2025 action raised position limits for options on certain bitcoin ETPs to 250,000 contracts. It also approved a fund holding both spot bitcoin and ether.

Which assets can now get a spot ETF?

Under the September 2025 generic standards, an asset generally qualifies if it meets one of three tests, according to FXStreet. It trades on a market that belongs to the Intermarket Surveillance Group. It has underlain a CFTC-regulated futures contract for at least six months. Or it is already the subject of an ETF with at least 40% exposure to it.

The SEC approved the Grayscale Digital Large Cap Fund the same day. That fund holds spot digital assets based on the CoinDesk 5 Index. Single-asset funds followed. BSOL launched Oct. 28, 2025, and stakes part of its SOL, according to Blockworks. Canary Capital's XRPC drew $58 million in first-day trading volume on Nov. 13, 2025, Decrypt reported.

Staking funds add steps that plain spot funds do not have. The trust locks up part of its coins with a blockchain network to earn rewards. That brings extra risks, including slashing penalties and limits on how quickly staked coins can be released.

FAQ

Do I own bitcoin if I buy a spot bitcoin ETF?

No. You own shares in a trust that holds bitcoin through a custodian. You cannot withdraw the coins or move them to a wallet.

Did the SEC endorse bitcoin when it approved spot ETFs?

No. In his Jan. 10, 2024 statement, then-Chair Gary Gensler said the SEC 'did not approve or endorse bitcoin.'

Why is GBTC more expensive than IBIT?

GBTC charges 1.50%, cut from 2% when it converted from an older trust, according to ETF Database. IBIT charges 0.25%. On $10,000, that works out to $150 a year versus $25.

What does in-kind redemption mean?

Since July 29, 2025, authorized participants can swap the crypto itself for ETF shares rather than using only cash. Supporters such as Commissioner Mark Uyeda said cash-only redemptions added trading costs and slippage.

Are crypto ETFs protected like mutual funds?

Spot crypto trusts such as ETHB are not registered under the Investment Company Act of 1940, according to BlackRock. They lack the protections that apply to mutual funds and '40 Act ETFs.
