Best Bitcoin ETFs: Top Funds for Buying Bitcoin

·

The rise of spot Bitcoin exchange-traded funds (ETFs) has transformed how investors gain exposure to cryptocurrency. For those looking to buy Bitcoin without managing private keys or navigating crypto exchanges, Bitcoin ETFs offer a secure, regulated, and cost-effective alternative. Since the U.S. Securities and Exchange Commission (SEC) approved spot Bitcoin ETFs in January 2024, mainstream investors can now access Bitcoin through traditional brokerage accounts—just like buying stocks.

This shift has lowered the barrier to entry, enabling everyday investors to participate in the digital asset market with greater ease and oversight. With multiple ETFs now available, it's essential to understand which options stand out based on performance, fees, and asset size.

What Are Bitcoin ETFs?

A Bitcoin ETF is an investment fund traded on stock exchanges that tracks the price of Bitcoin. Unlike buying Bitcoin directly on a crypto exchange, ETFs allow investors to gain exposure without holding the underlying asset. This means no need for digital wallets, private key management, or concerns about exchange security breaches.

These funds are especially appealing to risk-averse investors who want Bitcoin’s upside potential while staying within the framework of traditional finance. They also open doors for inclusion in retirement accounts and tax-advantaged portfolios—something difficult with direct crypto ownership.

Top Bitcoin ETFs in 2025

While all spot Bitcoin ETFs aim to mirror Bitcoin’s price movements closely, key differences lie in their expense ratios, total assets under management (AUM), and trading accessibility. Below are the leading funds shaping the market:

iShares Bitcoin Trust (IBIT)

With over $65 billion in assets, IBIT is the largest spot Bitcoin ETF. Backed by BlackRock, one of the world’s biggest asset managers, IBIT offers a low expense ratio of just 0.25%. Its massive scale suggests strong investor confidence and liquidity.

Fidelity Wise Origin Bitcoin Fund (FBTC)

Fidelity’s entry into the space brings institutional credibility and a user-friendly experience for existing Fidelity brokerage clients. FBTC holds over $20 billion in assets and charges the same 0.25% fee as IBIT, making it a competitive choice.

Grayscale Bitcoin Trust (GBTC)

Once the dominant player in indirect Bitcoin exposure, GBTC transitioned from a private trust to a publicly traded ETF. However, its 1.50% expense ratio is significantly higher than newer entrants, making it less attractive from a cost perspective despite its $19 billion AUM.

ARK 21Shares Bitcoin ETF (ARKB)

ARKB combines Cathie Wood’s innovation-focused investment approach with 21Shares’ expertise in digital assets. With a slightly lower expense ratio at 0.21% and solid performance tracking, ARKB appeals to growth-oriented investors.

Bitwise Bitcoin ETF Trust (BITB)

Bitwise offers one of the lowest fees at 0.20%, paired with transparent operations and strong custody practices. Though smaller in AUM at $3.9 billion, BITB has earned trust among retail and institutional investors alike.

ProShares Bitcoin ETF (BITO)

BITO was among the first futures-based Bitcoin ETFs but now competes in the spot market. Its 0.95% expense ratio and lower one-year return make it less favorable compared to newer, lower-cost alternatives.

VanEck Bitcoin ETF (HODL)

VanEck’s offering rounds out the list with strong performance and no publicized expense ratio yet. With $1.5 billion in assets, HODL benefits from VanEck’s long-standing reputation in commodity and digital asset investing.

All major spot Bitcoin ETFs track Bitcoin’s price with minimal tracking error. If Bitcoin rises 1%, these funds aim to rise approximately 1% as well—minus fees.

How to Choose the Right Bitcoin ETF

When selecting a Bitcoin ETF, focus on three main factors:

  1. Expense Ratio: Lower fees mean more of your returns stay in your pocket. Funds like BITB and ARKB lead here.
  2. Assets Under Management: Larger AUM often indicates stronger market confidence and better liquidity.
  3. Broker Availability: Ensure your brokerage supports trading the ETF you choose—most major platforms do.

👉 Compare low-cost, high-liquidity investment options available through trusted financial channels.

Given that most spot ETFs perform similarly in tracking Bitcoin, the deciding factor becomes cost efficiency. Think of it like choosing between identical products at two stores—one slightly cheaper. Over time, even small differences in fees compound significantly.

Frequently Asked Questions (FAQ)

Q: What is a spot Bitcoin ETF?
A: A spot Bitcoin ETF directly holds actual Bitcoin and aims to track its real-time market price, unlike futures-based ETFs that rely on derivatives contracts.

Q: Are Bitcoin ETFs safer than buying crypto on an exchange?
A: Yes. ETFs are regulated by the SEC, held in traditional brokerage accounts, and don’t require self-custody of private keys—reducing risks like hacking or loss.

Q: Do I own real Bitcoin when I buy a Bitcoin ETF?
A: No. You own shares in a fund that holds Bitcoin, not the cryptocurrency itself. But you still benefit from price appreciation.

Q: Can I hold a Bitcoin ETF in my IRA?
A: Yes, most major brokerages allow inclusion of Bitcoin ETFs in retirement accounts—a major advantage over direct crypto ownership.

Q: Why is the expense ratio important?
A: The expense ratio reduces your overall returns annually. A 1.5% fee can erode gains significantly over time compared to a 0.2% fee.

Q: Will more crypto ETFs be approved in the future?
A: Likely. After spot Bitcoin and Ethereum ETF approvals in 2024, other major cryptocurrencies may follow as regulatory frameworks evolve.

Should You Invest in a Bitcoin ETF?

Bitcoin ETFs simplify access—but they don’t change Bitcoin’s inherent volatility. The digital asset has historically experienced sharp price swings, which can test even seasoned investors’ resolve. Emotional decision-making—buying high after rallies and selling low during dips—remains a common pitfall.

Moreover, unlike stocks or bonds, Bitcoin isn’t backed by cash flows or tangible assets. Its value stems largely from market sentiment and speculation—the so-called “greater fool theory.” Legendary investor Warren Buffett has famously criticized it, calling Bitcoin “probably rat poison squared.”

Yet, proponents argue that limited supply (only 21 million Bitcoins will ever exist) and increasing institutional adoption support long-term value as a digital store of wealth—similar to gold.

Ultimately, whether a Bitcoin ETF belongs in your portfolio depends on your risk tolerance, investment goals, and belief in crypto’s future role.

Where Can You Buy Bitcoin ETFs?

You can purchase any of these top Bitcoin ETFs through major U.S. brokerage platforms such as Fidelity, Charles Schwab, Vanguard, or E*TRADE. Most offer commission-free trading on ETFs, meaning you can enter and exit positions with minimal transaction costs.

No special account setup is needed—just log into your existing brokerage account and search for the ticker symbol (e.g., IBIT or FBTC).
