In late September, U.S. investors put more than $2 billion into funds that hold Bitcoin, the largest digital currency, in a single week, the strongest week for those funds since October 2025.
Funds like these trade through brokerage accounts, the investing accounts people use to buy shares of companies like Apple, which is why they have changed how everyday people get into crypto.
What Are Crypto ETFs?
A crypto ETF is a type of exchange-traded fund, or ETF, which is an investment that trades on a stock exchange (a marketplace for buying and selling shares) just like a single company's stock.
The difference is that its value is tied to a cryptocurrency such as Bitcoin or ether, the digital currency of the Ethereum network, instead of to a company.
Because it trades like a stock, you buy it through a brokerage account, with no crypto wallet (an app or device that stores digital coins) to set up.
One example is BlackRock's iShares Bitcoin Trust, which trades under the ticker symbol IBIT, the short code used to look up a fund.
Suppose you buy $1,000 of a Bitcoin ETF and Bitcoin then rises 10%, so your shares should be worth about $1,100, minus the fund's yearly fee.
If Bitcoin falls 10% instead, they would be worth about $900, again minus the fee.
Why Do People Buy Crypto ETFs?
The appeal comes down to convenience and familiarity.
Use an Account You Already Have
If you already have a brokerage account, you can buy a crypto ETF in minutes, with no new app, password, or digital wallet to manage.
Your holdings also sit next to your stocks and other funds in one place.
Retirement Account Access
Many brokerages let you hold ETFs inside an IRA, or individual retirement account, a tax-advantaged account for retirement savings.
That can make crypto exposure possible in an account where buying coins directly typically is not an option.
Regulated Markets
Crypto ETFs list on regulated stock exchanges and file their documents with the Securities and Exchange Commission, or SEC, the federal agency that oversees investment markets.
How Do Crypto ETFs Work?
In the most common design, the fund company, called the issuer, buys the cryptocurrency and stores it with a custodian, a firm that safeguards assets on a client's behalf.
It then divides the holdings into shares, so each share is a small slice of the pile, and the share price rises and falls with the coin's price.
Funds charge for this service through an expense ratio, a yearly fee taken as a percentage of your investment.
Those fees vary widely, from roughly 0.14% to 1.5% a year across spot Bitcoin funds.
On $10,000, a 0.25% fee costs $25 a year, while a 1.5% fee costs $150.
The Main Types of Crypto ETFs
Spot Crypto ETFs
Spot funds hold the actual cryptocurrency, and they are the kind that has grown fastest since the SEC approved the first spot Bitcoin funds on January 10, 2024.
Spot ether funds followed later that year, and since the SEC approved generic listing standards in September 2025, which let exchanges list qualifying crypto funds without a separate SEC approval for each, funds tied to coins such as solana and XRP have launched too.
Futures Crypto ETFs
Futures funds hold futures contracts, which are agreements to buy or sell Bitcoin at a set price on a future date, instead of the coins themselves.
The first U.S. Bitcoin ETFs, launched in October 2021, were futures funds, and because those contracts must be replaced regularly, these funds can trail Bitcoin's actual price.
Basket Funds
A basket fund holds several coins at once, such as the Grayscale Digital Large Cap Fund, which the SEC approved in September 2025 and which tracks an index of leading digital assets.
Crypto Company Stock Funds
These funds hold shares of businesses tied to crypto, such as companies that mine coins (earn new ones by running specialized computers), rather than holding any coins.
Their prices tend to move with crypto but also with the fortunes of each business.
Does a Crypto ETF Mean You Own Crypto?
Not directly, because you own shares of a fund and the fund owns the crypto, so you cannot send the coins to a wallet or spend them.
SEC approval is also not an endorsement of crypto itself, and the agency's January 2024 statement on the first spot Bitcoin funds said plainly that approving them did not mean endorsing Bitcoin.
What Are the Risks of Crypto ETFs?
Big Price Swings
Crypto prices move far more than most stocks, and an ETF passes every move through to you.
Bitcoin fell about 75% from its late 2021 peak to its late 2022 low, and any fund holding it would have dropped alongside it, though past declines do not predict future ones, and past gains do not guarantee future gains.
Fees and Trading Hours
A fund's fee quietly trims your return every year, and ETF shares trade mainly during stock market hours while crypto itself trades around the clock.
That gap means a weekend price move shows up in your fund only after markets reopen on Monday.
Should You Buy a Crypto ETF or Crypto Directly?
An ETF is simpler and fits inside the accounts you already use, while buying crypto directly lets you hold the coins yourself, move them, and trade at any hour.
Direct buying also opens up far more coins than any ETF covers, though it means managing your own security.
If direct ownership appeals to you, Gemini lets you buy and hold crypto directly, without going through a fund.
If you go the ETF route, read the fund's prospectus, the plain-language document that lists its fee and holdings, before you buy.
