Bitcoin spot ETF and futures ETF: explain the differences, costs and applicable scenarios at once

Many people who come into contact with Bitcoin ETF for the first time will be stuck on the same question: What is the difference between spot and futures? The name only differs by two words, but the assets, price formation, and holding costs behind it are completely different. If you buy the wrong type, a big chunk of your long-term gains may be quietly eaten away.

Let’s first clarify what an ETF is. It's traded on an exchange like a stock, but behind it is a basket of assets. Traditional ETFs may hold stocks and commodities, while Bitcoin ETFs hold Bitcoin or contracts linked to the price of Bitcoin. Unlike mutual funds, ETFs can be traded at any time during the day, and the price follows supply and demand, without having to wait for the closing price to calculate the net value.

Spot ETF: Hold Bitcoin directly

The underlying asset of a spot ETF is real Bitcoin, which is managed by the fund. When you buy a fund share, it is equivalent to indirectly holding the corresponding number of Bitcoins. For example, if a fund holds 10,000 BTC and issues 1 million shares, each share would be worth 0.01 BTC. The net value of the fund will follow the spot price of Bitcoin, and the tracking will be relatively tight.

The U.S. Securities and Exchange Commission (SEC) approved the first Bitcoin spot ETFs on January 10, 2024. By 2025-2026, products led by BlackRock's IBIT (with a management scale of about $62 billion) and Fidelity's FBTC have combined assets of more than $102 billion, with about 1.3 million BTC locked in regulated custody.

The benefits of spot ETFs are straightforward: you don’t need to manage your own wallet or private key, you can buy them through an ordinary brokerage account, and they are under a regulatory framework with higher transparency. But there are also disadvantages: Bitcoin itself fluctuates greatly, and ETF prices fluctuate accordingly; although the management fee is lower than that of futures ETFs, mainstream products also charge 0.20-0.50%, which is higher than the handling fee of buying coins directly on the exchange; and what you get is only fund shares, not real Bitcoin, and cannot be transferred or used for on-chain operations.

Futures ETF: What you hold is a contract, not a currency

A futures ETF does not touch Bitcoin spot, it buys Bitcoin futures contracts - an agreement to buy or sell Bitcoin at a certain price on a certain date in the future. So your income depends on the market’s expectations of Bitcoin’s future price, not the current spot price.

Futures contracts have an expiration date, and positions must be rolled before expiration. If the far-month contract is more expensive than the near-month contract (this state is called contango, premium), you will have to pay a little more every time you switch positions. This will add up to a considerable cost in the long run and drag down fund performance. ProShares' BITO is the first Bitcoin futures ETF in the United States launched in 2021, with a fee rate of 0.95%. Due to the cost of swapping positions, long-term holdings often cannot outperform Bitcoin spot.

Futures ETFs also have their place: for people who are familiar with the futures market and want to do hedging or short-term price speculation. In areas where spot ETFs have not yet been approved, futures ETFs may be the only option. But the disadvantages cannot be ignored: there is no direct Bitcoin exposure, returns are affected by the structure of the futures market, there are counterparty risks, and management fees are higher.

Core difference: understand with one table

Comparison items	Bitcoin spot ETF	Bitcoin futures ETF
Underlying assets	Actual holdings of Bitcoin	Holding Bitcoin futures contracts
Price driven	Directly follows the real-time spot price of Bitcoin	Influenced by futures market dynamics and contract pricing
Price deviation	Usually closely tracks the spot price	May deviate due to premiums, swap costs, and contract expiration
Liquidity management	Hold and store Bitcoin, with low transaction frequency	Rolling swaps are required when contracts expire, and liquidity management is more active
Risk exposure	Direct exposure to Bitcoin price fluctuations	Indirect exposure, superimposed with futures market complexity and swap costs
Operational complexity	Bitcoin custody infrastructure required	Futures contract management expertise required
Typical rates (United States)	Mainstream products 0.20-0.50% (such as IBIT, FBTC)	Mainstream products above 0.95% (such as BITO)

**What products are available on the market? **

The largest Bitcoin spot ETF in the U.S. market right now is BlackRock’s IBIT, followed by Fidelity’s FBTC and ARK 21Shares’ ARKB. On the futures side, ProShares’ BITO is still dominant. The Ethereum spot ETF will be approved in May 2024 and listed in July. ETF applications for other digital assets have been submitted, but may not be approved by 2026.

When choosing an ETF, in addition to the type, you should also pay attention to the fee rate, the past record of the fund manager, and how closely the product tracks the target. If it is a futures ETF, be sure to include the switching cost into your holding period.

**Who is suitable to buy which one? **

For those who want direct exposure to Bitcoin’s price through a regulated exchange-traded product, but don’t want to fiddle with wallets and private keys, spot ETFs are more suitable. The structure is simple, similar to a stock or commodity ETF.

If you already understand the futures market and can accept the complexities of contract rolling, premium drag and indirect exposure, futures ETFs can be considered. Where spot ETFs are not yet approved, it may be the only type available.

A few frequently asked questions

Q: What is a Bitcoin spot ETF? A: An exchange-traded fund that holds real Bitcoin and whose performance tracks the real-time price of the Bitcoin spot market. There are no contracts to roll over and tracking errors are generally lower. The first U.S. spot ETFs were approved in January 2024.

Q: What is a Bitcoin Futures ETF? Answer: Funds that hold Bitcoin futures contracts are betting on future prices rather than spot prices. The contract needs to be rolled over when it expires, especially in the premium market, and the performance may deviate from the spot price.

Question: The core difference between the two? Answer: The underlying assets are different. Spot ETFs hold real currency and directly track the current market price; futures ETFs hold contracts, which are subject to swap costs, premium drag and market complexity. Since the approval of spot ETFs in the United States in 2024, spot products have attracted significantly more capital.

Q: Can all investors buy Bitcoin ETFs? A: It depends on your jurisdiction and brokerage channel. U.S. spot and futures ETFs are listed on regulated exchanges and can generally be purchased through an ordinary brokerage account. Other countries depend on local regulatory approval.

Final Reminder

Bitcoin ETFs open the door for traditional investors to participate in price fluctuations without directly holding the currency. However, the difference between spot and futures will be reflected in returns in the long run. Before buying, read the fund prospectus to find out the rates, tracking methods and product features, and then compare it with your risk tolerance. Digital assets are highly volatile and you may lose your principal. Don’t treat ETFs as a tool for making sure profits.
