Bitcoin ETF: A Simple Explanation of How They Operate

What Is a Bitcoin ETF?

A Bitcoin ETF (Exchange-Traded Fund) is a financial product that allows investors to gain exposure to the price movements of Bitcoin without directly owning the cryptocurrency. Instead of purchasing and storing Bitcoin on a digital wallet, investors can buy shares of the ETF through traditional stock exchanges. These funds are typically managed by asset management firms and regulated by financial authorities such as the U.S. Securities and Exchange Commission (SEC). The key appeal of a Bitcoin ETF lies in its ability to offer regulated, accessible, and secure exposure to Bitcoin for both retail and institutional investors.

The structure of a Bitcoin ETF is designed so that its share price closely tracks the value of Bitcoin. This is achieved through direct ownership of Bitcoin (in the case of spot ETFs) or through financial derivatives like futures contracts (in futures-based ETFs). The most significant distinction lies in whether the fund holds actual Bitcoin or uses derivative instruments to mirror its price.

Spot vs. Futures-Based Bitcoin ETFs

There are two primary types of Bitcoin ETFs: spot Bitcoin ETFs and futures-based Bitcoin ETFs. Each operates differently and carries distinct implications for investors.

• A spot Bitcoin ETF holds actual Bitcoin in secure custody. The fund purchases and stores Bitcoin, and each share of the ETF represents a fractional ownership of that underlying asset. This model provides direct exposure to Bitcoin’s market price. The value of the ETF fluctuates in real time with the price of Bitcoin, minus management fees and operational costs. Regulatory approval for spot Bitcoin ETFs has been challenging due to concerns over market manipulation and custody practices.

• A futures-based Bitcoin ETF, on the other hand, does not hold Bitcoin directly. Instead, it invests in CME-traded Bitcoin futures contracts. These contracts obligate the buyer to purchase Bitcoin at a predetermined price at a future date. Because futures prices may not always align with the spot price of Bitcoin, this type of ETF can exhibit contango or backwardation, potentially leading to tracking errors over time.

Investors should understand that futures-based ETFs may not perfectly replicate long-term Bitcoin price movements due to the need to roll contracts as they expire, which can incur additional costs.

How a Bitcoin ETF Is Created and Traded

The creation and trading process of a Bitcoin ETF involves several key players: authorized participants (APs), custodians, the fund issuer, and stock exchanges.

• Authorized participants are large financial institutions that create or redeem ETF shares in large blocks known as creation units. To create new shares, an AP deposits either cash or the underlying asset (in this case, Bitcoin for spot ETFs) with the fund. In return, the AP receives a block of ETF shares.

• For spot Bitcoin ETFs, the AP typically delivers Bitcoin to the fund’s custodian. The custodian, often a regulated financial institution with cold storage solutions, securely holds the Bitcoin. Once the deposit is confirmed, the AP receives ETF shares that can be sold on the open market.

• These shares are then listed on major stock exchanges such as the NYSE or Nasdaq, where individual investors can buy and sell them during market hours using a standard brokerage account. The trading mechanism is identical to that of traditional ETFs or stocks.

• The continuous interaction between APs and the ETF ensures that the market price of the ETF stays close to its net asset value (NAV). If the ETF trades at a premium, APs can create more shares to profit from the price difference, thus bringing the price back in line.

Custody and Security Mechanisms

Security is a critical component of spot Bitcoin ETFs, as they involve holding actual Bitcoin. To mitigate risks, these funds employ institutional-grade custodians with robust security protocols.

• The custodian stores the Bitcoin in cold storage wallets, which are offline and disconnected from the internet, reducing the risk of hacking.

• Multi-signature wallets are commonly used, requiring multiple private keys to authorize transactions. This prevents any single entity from having full control over the assets.

• Regular audits and attestations are conducted to verify the amount of Bitcoin held. These reports are made available to regulators and sometimes to the public.

• Insurance policies are often in place to protect against theft or loss. Some custodians partner with specialized crypto insurance firms to cover digital asset holdings.

These measures aim to address one of the SEC’s primary concerns: ensuring that the underlying asset is securely held and verifiable.

Fees and Expense Ratios

Bitcoin ETFs charge an expense ratio, which is an annual fee expressed as a percentage of the assets under management (AUM). This fee covers operational costs, custody, management, and administrative expenses.

• Expense ratios for Bitcoin ETFs vary. Early spot Bitcoin ETFs launched in the U.S. have ranged from 0.20% to 0.90% annually.

• Lower fees are typically used as a competitive advantage to attract large institutional investors. Some providers have offered waived or reduced fees during initial launch periods to gain market share.

• Investors should be aware that even small differences in expense ratios can significantly impact long-term returns, especially in a volatile asset like Bitcoin.

• Additional costs may include brokerage commissions when buying or selling shares, though many platforms now offer commission-free ETF trading.

It is essential to review the ETF’s prospectus to understand the full fee structure, including any potential hidden costs related to futures contract rolling or rebalancing.

Frequently Asked Questions

Can I redeem Bitcoin ETF shares for actual Bitcoin?No, investors cannot redeem shares of a Bitcoin ETF for physical Bitcoin. The shares represent ownership in the fund, not direct ownership of the cryptocurrency. Only authorized participants have the ability to exchange creation units for Bitcoin, and this process is not available to retail investors.

How does a Bitcoin ETF affect the price of Bitcoin?A Bitcoin ETF can influence Bitcoin’s price by increasing institutional demand. When an ETF is approved and gains inflows, the authorized participants may need to purchase Bitcoin to back new shares, creating upward pressure on the price. However, the long-term impact depends on the volume of capital entering the ETF and broader market conditions.

Are Bitcoin ETFs available globally?Yes, Bitcoin ETFs are available in several countries, including the United States, Canada, Brazil, and parts of Europe. However, regulatory approval and product structures vary by region. For example, Canada’s Purpose Bitcoin ETF was one of the first spot Bitcoin ETFs approved, while U.S. regulators initially approved only futures-based ETFs before allowing spot ETFs in 2024.

Do Bitcoin ETFs pay dividends?No, Bitcoin ETFs do not pay dividends. Bitcoin itself does not generate income, and since the ETF holds either Bitcoin or futures contracts, there is no revenue stream to distribute. The return on investment comes solely from changes in the share price relative to Bitcoin’s market value.
