A spot bitcoin ETF is a fund whose shares trade on a stock exchange and follow the bitcoin price, while the fund holds the coins. Owning bitcoin directly means the coins sit in a wallet you control. ETF holders avoid managing keys but cannot send or spend bitcoin. Direct owners can move their coins but must keep them secure.
The main difference between a bitcoin ETF and owning bitcoin is what you actually hold. A spot bitcoin ETF (exchange-traded fund) gives you shares in a fund that holds bitcoin, and the fund keeps the coins. When you own bitcoin directly, the coins sit in a wallet you control. You can send or spend them, but keeping them safe is up to you. New to the asset itself? Start with what Bitcoin is and how it works.
This guide compares the two routes: what you own, what you pay, when you can trade, who holds the keys and how tax accounts treat each one. It explains how they work, not which one to choose. Coinmama is a cryptocurrency exchange where you buy bitcoin itself, not fund shares. See the Bitcoin price and payment options.
How do a bitcoin ETF and owning bitcoin compare side by side?
Both follow the bitcoin price, but they differ in what you hold, who holds the keys, when you can trade and what you pay along the way. The table sums up the main differences, and the sections below explain each one.
| Feature | Spot bitcoin ETF (or ETN) | Owning bitcoin directly |
|---|---|---|
| What you hold | Shares in a fund, or a note | The bitcoin itself |
| Private keys | Held for the fund by its custodian | Held by you, or by a service you choose |
| Send or spend bitcoin | No | Yes |
| Where it sits | A brokerage or retirement account | A crypto wallet |
| When you can trade | During stock exchange sessions on weekdays | Any day, at any hour |
| Ongoing costs | Yearly fund fee, plus broker costs | Network fees when you move coins; no yearly fee in your own wallet |
| Main risks besides price | The fund, its custodian, your broker (and the issuer, for a note) | Lost keys, scams and wrong addresses |
| Tax-advantaged accounts | Sometimes: IRAs in the US if your provider allows; UK pensions and Innovative Finance ISAs for crypto ETNs (cETNs) | Depends on local rules |
What is a spot bitcoin ETF?
A spot bitcoin ETF is a fund that holds actual bitcoin and whose shares trade on a stock exchange, like company shares. Its share price follows the bitcoin price, minus the fund’s fees.
In the US, the Securities and Exchange Commission (SEC) approved the listing and trading of the first spot bitcoin exchange-traded products on January 10, 2024. The SEC’s chair at the time stressed that the agency had not approved or endorsed bitcoin itself.
Most US spot bitcoin funds are set up as exchange-traded commodity trusts. That is why official documents call them exchange-traded products (ETPs) rather than ETFs. They are not covered by the Investment Company Act of 1940, the US law behind mutual funds and most ETFs, so that law’s rules on valuing and safekeeping fund assets do not apply to them. Most people still say “bitcoin ETF”, and this guide does too. For the commodity side of the story, read whether bitcoin is a commodity.
Futures-based bitcoin funds work differently. They hold futures contracts, which are agreements linked to bitcoin’s future price, not the coins themselves.
What do you actually own?
With an ETF, you own shares in a fund, and the fund owns the bitcoin. You never hold the private key (the secret code that controls coins). So you cannot move the bitcoin to a wallet, send it to someone or pay with it. When you sell your shares, you receive cash, not bitcoin.
When you own bitcoin directly, the coins are recorded on the bitcoin network under addresses that your keys control. You can hold them, send them to anyone, move them to a cold wallet (a wallet kept offline) or sell them. You do not need a whole coin either: you can buy a fraction of a bitcoin.
How do the costs compare?
Both routes cost money, but you pay in different places. A fund charges a yearly fee, while direct owners pay mainly when they buy and when they move coins.
What does a bitcoin ETF cost?
- A yearly sponsor fee (often called the expense ratio), which pays the fund’s running costs. The fund pays it out of its bitcoin, so the amount of bitcoin behind each share shrinks a little over time. Fees vary by fund, so check the prospectus.
- Trading costs: any commission your broker charges, plus the bid-ask spread (the gap between the buying and selling price of the shares).
- Tracking gaps: the share price can move slightly away from the value of the bitcoin the fund holds.
What does owning bitcoin directly cost?
- Buying costs: a fee or spread when you buy, which depends on the service and how you pay.
- Network fees when you send bitcoin. These go to the miners who confirm transactions, not to the seller, and they rise and fall with demand.
- Storage: the price of a hardware wallet, if you want one. There is no yearly fee on coins held in your own wallet.
Coinmama does not add its own fee. All fees are shown before you confirm your order. For details, see how fees work on Coinmama. Which route costs less overall depends on how much you put in, how long you hold and how often you move coins.
When can you buy or sell?
You can trade ETF shares only while the stock exchange is open, but the bitcoin network never closes. This matters most at weekends, when the bitcoin price can move while stock markets are shut.
On the New York Stock Exchange, the core trading session runs from 9:30 a.m. to 4:00 p.m. Eastern Time on trading days. Some exchanges add early and late sessions, and US exchanges are moving toward longer weekday hours: in April 2026, the SEC approved Nasdaq’s plan to trade 23 hours a day, five days a week. Even so, US stock exchanges are closed on Saturdays and on market holidays (as of September 2026).
The bitcoin network runs every day, at any hour, including weekends and holidays. The service you buy or sell through may have its own processing steps, and each transaction needs network confirmations. See blockchain delays and confirmations for how that works.
Who looks after the bitcoin?
With an ETF, a custodian holds the fund’s bitcoin. With direct ownership, you are the custodian, unless you choose a service to hold your coins for you.
How does custody work in a fund?
Your broker holds your shares, and a custodian named in the fund’s documents holds the fund’s bitcoin. You never handle keys, but you rely on the fund, its custodian and your broker. The fund itself still faces the risks of holding crypto, such as theft or lost keys. The SEC expects these funds to explain how their keys are stored (cold, warm or hot storage) and what insurance, if any, the custodian carries, so those sections of the prospectus are worth reading.
What does self-custody involve?
In a self-custody wallet, you keep a seed phrase (the backup words that restore your wallet). If you lose it and your device, nobody can restore your coins. Bitcoin transactions also cannot be reversed once confirmed, so sending to a wrong address usually means the coins are lost.
Before you decide where to keep coins, read what happens if you lose your private keys and compare hot and cold wallets. Leaving coins with a service that holds the keys is simpler, but then you rely on that service, much as a fund holder relies on a custodian.
Can you buy a bitcoin ETF outside the US?
It depends on where you live and what your broker offers. Outside the US, bitcoin products on stock exchanges often take a different legal form:
- UK: since October 8, 2025, the Financial Conduct Authority (FCA) has let retail investors buy crypto exchange-traded notes (cETNs) that trade on a UK investment exchange the FCA has approved. cETNs are debt securities that track a cryptoasset. The FCA says they are not covered by the Financial Services Compensation Scheme (FSCS).
- EU: exchanges such as Germany’s Xetra list crypto exchange-traded notes (ETNs) that track bitcoin. Deutsche Börse, which runs Xetra, notes that investors do not need their own wallets or keys to trade them.
A note is a debt of the company that issues it, so you also rely on that issuer. Products, access and investor protections differ by country, so check what brokers in your country offer and read the product documents first.
How are they taxed, and can they go in an IRA or ISA?
Tax depends on where you live and on the product, so treat this as a starting point only. Both routes can create a taxable gain when you sell.
- US: the IRS treats digital assets such as bitcoin as property, so selling bitcoin can create a capital gain or loss. Fund shares held as an investment are capital assets too, so selling them can also create a gain or loss. Each fund’s prospectus explains how it is taxed. Whether you can hold bitcoin fund shares in an IRA depends on your account, because most IRA custodians limit holdings to investments they approve.
- UK: since October 8, 2025, cETNs can be held in UK pension schemes. From April 6, 2026, new cETN purchases can go only in an Innovative Finance ISA, not a stocks and shares ISA. cETNs already held in a stocks and shares ISA before then can stay. These rules cover cETNs, not bitcoin held in your own wallet.

Which approach might suit you?
There is no single right answer, and this guide does not recommend either route. These are points to weigh, not advice.
A fund may fit better if you:
- Already invest through a brokerage or retirement account and want everything in one place.
- Only want exposure to the price and have no plans to send or spend bitcoin.
- Would rather not manage keys or a seed phrase.
Owning bitcoin directly may fit better if you:
- Want to hold the asset itself and move it whenever you like.
- Want to use bitcoin, for example to send value abroad or to pay someone.
- Are ready to learn wallet security and take responsibility for your backup.
Some people use both. Either way, the price risk is the same, because both rise and fall with bitcoin. To understand what moves that price, read how bitcoin’s price is determined.
How do you buy bitcoin directly?
You need a wallet, an account with a service that sells bitcoin, and a careful eye on the address you enter. The usual steps are:
- Set up a wallet. Create a wallet you control and write its seed phrase down offline. Our guide to what a crypto wallet is covers the options.
- Open an account and verify your identity. Services that sell crypto ask for identity checks before you buy.
- Choose an amount and a payment method. Check the fees and the final amount before you confirm.
- Enter your wallet address and confirm. Copy the address carefully and check it again.
