The launch of spot Bitcoin ETFs in early 2024 marked a transformative moment in digital asset investing. For the first time, investors gained regulated, stock-market-accessible exposure to Bitcoin’s price through funds that directly hold the cryptocurrency—a major leap from earlier futures-based alternatives.
This guide delivers a clear, up-to-date breakdown of Bitcoin spot ETFs and strategy ETFs, including their expense ratios, assets under management (AUM), and key differences. Whether you're new to crypto investing or refining your portfolio, this overview equips you with the insights needed to make informed decisions.
What Are Bitcoin ETFs?
Bitcoin ETFs (Exchange-Traded Funds) are investment vehicles that trade on traditional stock exchanges like the NYSE or NASDAQ. Instead of buying Bitcoin directly on a crypto exchange, investors can purchase shares of a Bitcoin ETF through their brokerage account.
These funds are designed to track the price of Bitcoin, allowing investors to benefit from its price movements without managing wallets, private keys, or storage security.

How Do Bitcoin ETFs Work?
A Bitcoin ETF functions like any other ETF: its share price reflects the value of its underlying assets. In the case of a spot Bitcoin ETF, each share represents a fraction of physically held Bitcoin. When Bitcoin’s market price increases, so does the ETF’s net asset value (NAV), and vice versa.
Because these funds trade on regulated stock markets, they offer:
- Seamless integration into traditional investment accounts
- Real-time pricing during market hours
- No need for self-custody or blockchain know-how
This structure lowers the entry barrier for mainstream investors while maintaining alignment with Bitcoin’s performance—minus management fees.
Why Invest in Bitcoin ETFs?
Bitcoin ETFs provide a secure and convenient path to crypto exposure. Here’s why they appeal to both retail and institutional investors:
- Simplified Access: No need to navigate crypto exchanges or manage digital wallets.
- Regulatory Oversight: Listed on major exchanges and subject to SEC regulations.
- Liquidity: Can be bought and sold instantly during trading hours.
- Security: Custody is handled by professional firms, reducing risk of theft or loss.
- Portfolio Diversification: Easily integrate Bitcoin into a mixed-asset investment strategy.
For those wary of crypto’s technical complexity, ETFs offer peace of mind and regulatory transparency.
Spot Bitcoin ETFs: Direct Exposure to BTC
A spot Bitcoin ETF holds actual Bitcoin as its primary asset—similar to how gold ETFs hold physical bullion. This direct ownership model ensures the fund closely tracks Bitcoin’s real-time market price.
Before 2024, U.S. investors only had access to futures-based Bitcoin ETFs, which rely on derivative contracts rather than actual BTC holdings. The SEC’s approval of spot Bitcoin ETFs in January 2024 changed the game, opening the door for trusted asset managers like Fidelity and BlackRock to enter the space.
These ETFs are ideal for long-term investors who want pure Bitcoin exposure without operational hassles.

Bitcoin Futures ETFs: Indirect Market Access
Unlike spot ETFs, Bitcoin futures ETFs do not hold actual Bitcoin. Instead, they invest in futures contracts—agreements to buy or sell Bitcoin at a set price on a future date.
While these funds aim to reflect Bitcoin’s price trends, their performance can diverge due to:
- Rolling contracts (monthly expiration and renewal)
- Contango or backwardation in futures markets
- Higher volatility compared to spot prices
Futures ETFs were the first form of regulated Bitcoin access in the U.S., launching in 2021 with ProShares’ BITO.
Are Strategy ETFs the Same as Futures ETFs?
Not exactly.
While Bitcoin futures ETFs are a subset of strategy ETFs, the broader category includes funds that invest in:
- Bitcoin mining companies
- Blockchain technology equities
- Crypto-related derivatives
- Multi-asset crypto strategies
Strategy ETFs offer indirect exposure and often have more complex risk-return profiles than spot or futures-only funds.
Key Differences: Futures vs Strategy ETFs
- Focus: Futures ETFs target price via contracts; strategy ETFs may include equities and leveraged instruments.
- Tracking Accuracy: Futures funds often suffer tracking errors; strategy funds may deviate further due to diversified holdings.
- Volatility: Futures contracts amplify short-term swings; strategy funds vary based on asset mix.
- Use Case: Futures suit short-term traders; strategy funds appeal to those seeking broader ecosystem exposure.

Risks and Challenges of Bitcoin ETFs
While convenient, Bitcoin ETFs are not without risks:
