Spot Bitcoin ETFs vs Bitcoin Futures ETFs: Which is Better?

Bitcoin futures and spot ETFs are continuing to grab the market’s attention. As of January 2025, over 5.7% of all Bitcoin is held by ETFs. That’s more than $36 billion in net inflows into U.S. spot Bitcoin ETFs since they launched just a year ago.

However, not all Bitcoin ETFs are created equal. Some track futures contracts, while others hold actual Bitcoin.

This article explains the differences between Bitcoin Futures ETFs and Bitcoin spot ETFs.

What are Bitcoin ETFs?

An ETF, or exchange-traded fund, is a type of investment product that trades on stock exchanges. It lets you invest in an asset, like Bitcoin, without directly owning or managing it.

In 2024, Bitcoin’s network handled over $19 trillion, more than double the $8.7 trillion from 2023. That massive jump isn’t just from retail traders. 

A Bitcoin ETF gives you exposure to Bitcoin through the stock market. You buy it like you’d buy Apple, Starbucks, or Tesla shares.

What are the differences between the Bitcoin ETFs?

Not all Bitcoin ETFs work the same way. The biggest difference is what they’re investing in.

A Bitcoin Futures ETF doesn’t hold any actual Bitcoin. Instead, it invests in Bitcoin futures. In other words, agreements to buy or sell Bitcoin at a set price on a future date. These contracts are traded on regulated commodity exchanges like the Chicago Mercantile Exchange (CME).

On the other hand, a Bitcoin spot ETF holds real Bitcoin. It tracks the current price, or “spot” price, of Bitcoin in real time. When you buy a spot ETF, the fund holds Bitcoin on your behalf.

This difference changes everything, from how each ETF performs to the level of risk involved.

Futures ETFs can lag behind actual Bitcoin prices or move differently because they’re based on contracts, not the asset itself. They can also roll contracts monthly, which may lead to added costs. Spot ETFs stay much closer to the live market price.

Knowing which type of crypto ETF to invest in is key. Both are labeled BTC ETFs but behave very differently once you’re in.

Why do Bitcoin ETFs matter?

Bitcoin ETFs make crypto investing easier, especially if you’re not ready to manage private keys or use crypto wallets. You can buy exposure to Bitcoin through your regular brokerage account — no need to sign up for a crypto exchange.

They help bridge traditional finance and crypto, giving people a familiar way to invest in something that used to feel risky or out of reach.

That simplicity attracts a much wider group of investors, including big institutions. When more people have access, demand can grow, which may help Bitcoin’s price stay stable over time.

BTC ETFs can be added to retirement accounts or long-term investment portfolios without breaking rules or jumping through hoops. That’s something you can’t easily do with regular Bitcoin holdings.

For many, BTC ETFs turn Bitcoin from a fringe asset into something that feels more mainstream and trusted.

How do Bitcoin Futures ETFs work?

Bitcoin Futures ETFs don’t own Bitcoin directly. 

Instead, they invest in futures contracts, which are agreements to buy or sell Bitcoin at a set price on a future date. These contracts are traded on the CME (Chicago Mercantile Exchange).

When you invest in a Bitcoin Futures ETF, the fund manages a mix of these contracts, usually short-term ones. The goal is to track the price of Bitcoin, but because it uses contracts instead of the actual asset, the performance can sometimes drift from spot prices.

Futures ETFs also deal with something called contract rolling. That means when a contract is about to expire, the fund has to sell it and buy a new one. This process can lead to extra costs or losses, especially in volatile markets.

While the ETF is providing exposure to Bitcoin, it’s a more complex setup. Futures ETFs are often used by investors looking for short-term trades or institutions already familiar with commodity markets.

If you’re thinking long-term or want price accuracy, futures may not always behave as expected.

How do Spot Bitcoin ETFs work?

Spot Bitcoin ETFs are much simpler. 

They directly buy and hold real Bitcoin on your behalf. When you purchase a share, you get a slice of actual Bitcoin held in secure custody by the fund.

Unlike futures ETFs, there are no contracts or expiration dates to manage. The value of a spot ETF closely tracks the real-time market price, also known as the spot price, of Bitcoin.

Behind the scenes, the fund works with trusted custodians to store the Bitcoin safely, usually in cold wallets (offline storage). Coinbase is powering at least 9 BTC ETFs. That keeps your investment secure without you needing to handle keys or wallets.

Spot ETFs are especially appealing for long-term investors. You can buy them through traditional platforms like Fidelity or Schwab, and even include them in retirement accounts.

Bitcoin ETFs pros and cons

Whether you’re after long-term exposure or short-term bets, knowing the pros and cons of each ETF type is key. Below is a clear breakdown of what each offers and what you should watch out for.

Bitcoin Futures ETFs pros	Bitcoin Futures ETFs cons
Accessible through traditional brokerage accounts	Higher management and operational fees
No need to store actual Bitcoin (avoids custody risks)	The futures market can be illiquid
Available on major U.S. exchanges (NYSE, Nasdaq)	Price may diverge from BTC due to contango/backwardation
Familiar format, similar to commodity ETFs	Tracking fluctuation due to rolling, fees, and market volatility
Suitable for short-term trading and speculation	Rolling futures adds complexity and cost
Offers access to inverse or leveraged Bitcoin exposure	Poor tracking of BTC’s long-term price performance

Spot Bitcoin ETFs pros	Spot Bitcoin ETFs cons
Direct exposure	Requires secure custody, adding operational complexity
Lower fees than futures ETFs	Security risks if custodian is compromised
Simple structure, no contract rollovers	Increases BTC volatility by attracting speculative capital
Boosts BTC demand and potentially its price	Risk of centralizing Bitcoin ownership via institutional control
Allows traditional investors to own BTC without self-custody	Only trades during market hours (BTC trades 24/7)

Bitcoin ETFs performance compared: Futures versus Spot 

The performance gap between spot Bitcoin ETFs and Bitcoin Futures ETFs has widened, with spot ETFs taking the lead.

They attracted significant investor interest, amassing over $121 billion in assets under management (AUM) by early 2025, while U.S.-listed Bitcoin Futures ETFs collectively manage less than $3 billion.

BlackRock’s iShares Bitcoin Trust (IBIT) alone has accumulated more than $52.3 billion, making it one of the most successful ETF launches in U.S. history. Fidelity’s FBTC and ARK 21Shares’ ARKB have also seen strong inflows, with FBTC reaching nearly $19 billion in AUM.

In contrast, Bitcoin Futures ETFs have struggled to keep pace. The leading futures-based product, ProShares Bitcoin Strategy ETF (BITO), manages just $2.18 billion in AUM. 

While futures ETFs provided early access to Bitcoin exposure, their structure introduces tracking discrepancies and higher costs. As a result, investor preference has shifted toward spot ETFs, which more accurately reflect Bitcoin’s market price. 

For context, on average, IBIT trades over 45 million shares daily, significantly more than BITO’s 8.5 million, highlighting the growing dominance of spot-based funds.

The data indicates that spot Bitcoin ETFs have outperformed futures-based ETFs regarding asset growth and investor inflows in 2025. This trend underscores the growing demand for direct and efficient exposure to Bitcoin through regulated investment vehicles.

Key players behind Bitcoin Futures and Spot ETFs 

The Bitcoin ETF space has exploded. In 2024 alone, 43 crypto ETF launches occurred, with over half focused on spot Bitcoin or Ether. U.S. investors have access to 11 approved spot Bitcoin ETFs, and total assets across all Bitcoin ETFs have hit $120 billion just over a year since launch.

On the futures ETF side, ProShares made history with BITO, the first U.S. Bitcoin-linked ETF. Valkyrie followed with BTF, which was tailored more for active traders. VanEck also joined with XBTF, appealing to investors seeking low fees and traditional fund management.

For spot Bitcoin ETFs, BlackRock’s iShares Bitcoin Trust (IBIT) is the front-runner with $52.9 billion AUM, reaching that figure faster than any ETF in history. Fidelity’s FBTC and Grayscale’s GBTC remain major players. ARK Invest and 21Shares teamed up on ARKB, while Bitwise launched BITB, backed by a crypto-native team.

Together, these ETFs have generated $36.2 billion in net inflows and daily volumes of over $5 billion.

Management fees: Futures vs. Spot ETFs 

Even if two ETFs track the same asset, their management fees differ and may quietly dent future returns.

Bitcoin Futures ETFs	Ticker	Management Fee
Valkyrie Bitcoin and Ether Strategy ETF	BTF	1.24%
Bitwise Bitcoin Strategy Optimum Roll ETF	BITC	0.92%
ProShares Bitcoin Strategy ETF	BITO	0.95%
Spot Bitcoin ETFs
Bitwise Bitcoin ETF	BITB	0.20%
ARK 21Shares Bitcoin ETF	ARKB	0.21%
iShares Bitcoin Trust	IBIT	0.25%

Spot Bitcoin ETFs typically have lower fees than Futures ETFs, making them more cost-effective for long-term investors.

However, other factors such as liquidity, tracking accuracy, and the specific investment strategy of each ETF should be considered.

How are Bitcoin Futures and Spot ETFs regulated?

Bitcoin Futures ETFs are overseen by the Commodity Futures Trading Commission (CFTC) since they rely on futures contracts traded on the CME. 

These ETFs fall under the Investment Company Act of 1940, which brings strict reporting and compliance rules.

Spot Bitcoin ETFs, on the other hand, are regulated by the Securities and Exchange Commission (SEC). Because they hold actual Bitcoin, the SEC evaluates how the fund secures assets, values holdings, and protects investors.

Both ETF types must meet U.S. financial regulations. Still, the key differences are what they track, futures contracts vs. real Bitcoin, and which agency oversees their operation.

Buying and holding Bitcoin versus BTC ETFs

Whether you’re deciding between buying Bitcoin directly or investing in a BTC ETF, the decision is based on control vs. convenience.

Buying Bitcoin means you own the asset. You can move it, store it in a cold wallet, and use it however you want. But that also means you’re fully responsible for keeping it safe. Lose your private keys? It’s gone. There’s no customer service to help you recover it.

With a Bitcoin ETF, you don’t own the Bitcoin — you own shares representing its exposure. Buying and selling is easier, and you can do it right from your brokerage account. But you’re trusting a third party to manage everything behind the scenes.

Both options have their place. 

Holding Bitcoin directly makes sense if you’re tech-savvy and want full control. But if you’re looking for a more straightforward way to get exposure, especially through retirement or taxable investment accounts, Bitcoin ETFs are a smart alternative.
