Crypto index funds and passive strategies: a complete directory

Spot Bitcoin ETFs changed everything. For the first time, investors can get crypto market exposure for under 0.25% per year through a brokerage account. But the passive crypto landscape goes far beyond Bitcoin ETFs. Here is the full picture of crypto index products, multi-asset trackers, and how passive compares to active management.

Key takeaways
  • Spot Bitcoin ETFs launched in January 2024 and have attracted $75+ billion in cumulative AUM, making them the fastest-growing ETF category in history. The cheapest charge 0.20% per year.
  • Multi-asset crypto index products are now available as ETFs, including Grayscale’s CoinDesk Crypto 5 ETF (GDLC) covering BTC, ETH, ADA, XRP, and SOL, roughly 90% of crypto’s investible market cap.
  • Bitwise’s BITW tracks the top 10 crypto assets by market cap, rebalanced monthly. Dozens of new crypto strategy ETFs have been filed covering DeFi, AI tokens, and specific protocol tokens.
  • In CFR’s data, index/tracker funds have the highest beta to Bitcoin (0.93) and the lowest Sharpe ratio (approximately 0.70) of any strategy category. You get market exposure, not alpha.
  • The passive vs. active debate in crypto mirrors the same debate in equities: passive wins on fees and simplicity, active wins on risk management and downside protection. In bull markets passive usually outperforms active. In bear markets active usually loses less.
  • For many allocators, the answer is a core-satellite approach: passive crypto ETFs for cheap market exposure (the core) plus 1-2 active managers for alpha and risk management (the satellites).

The passive crypto landscape in 2026

Two years ago, there were essentially no regulated passive crypto investment products in the United States. Today, there are spot Bitcoin ETFs from BlackRock, Fidelity, Bitwise, Grayscale, and others. There are spot Ethereum ETFs. There are multi-asset crypto index ETFs. There are ETF filings for Solana, XRP, Dogecoin, Chainlink, and even Hyperliquid’s HYPE token. The expansion of passive crypto products has been one of the most significant developments in institutional crypto since the asset class was created.

This matters for the crypto fund industry because passive products are the benchmark that active managers must beat (although Bitcoin itself is often a benchmark as well). Before 2024, if you wanted crypto exposure, you either bought tokens directly (operationally complex for institutions) or invested in a crypto fund (expensive). Now you can get Bitcoin exposure through IBIT for 0.25% per year or through Bitwise’s BITB for 0.20%. That changes the value proposition for every active crypto fund. The question is no longer “can this fund give me crypto exposure?” Its “can this fund give me enough alpha over a cheap ETF to justify the fee premium?”

Spot Bitcoin ETFs

The January 2024 approval of 11 spot Bitcoin ETFs was a watershed moment. Within their first year, these products attracted over $75 billion in cumulative AUM, making them the most successful ETF launch in history. BlackRock’s iShares Bitcoin Trust (IBIT) alone became one of the 50 largest ETFs in the world within months of launch.

The fee war has driven costs down dramatically. Grayscale’s BTC Mini Trust charges just 0.15%, and several competitors are at 0.20-0.25%. At these prices, the expense ratio is a rounding error for most institutional portfolios. The meaningful differentiation between spot BTC ETFs is liquidity (IBIT dominates), custodial model (Fidelity uses its own custody), and transparency (Bitwise publishes a public proof-of-reserves page with downloadable auditor attestation).

Spot Ethereum ETFs followed, with Grayscale’s ETHE and ETH products alongside competitors. And the pipeline keeps expanding: as of early 2026, there are ETF filings for Solana (Grayscale GSOL), XRP (Grayscale GXRP), Dogecoin, Chainlink, and more. Bitwise alone has filed for 11 new strategy ETFs covering tokens from AAVE to ZEC.

Multi-asset crypto index products

Single-asset ETFs give you exposure to Bitcoin or Ethereum individually. But many allocators want diversified crypto exposure without picking individual tokens. This is where multi-asset index products come in.

Grayscale CoinDesk Crypto 5 ETF (GDLC) tracks the top five crypto assets by market cap: Bitcoin, Ethereum, Cardano, XRP, and Solana. Together, these represent approximately 90% of crypto’s investible market cap. The product uses the CoinDesk indices as its benchmark and rebalances to maintain market-cap-weighted exposure. Grayscale describes this as the beginning of “index investing for crypto,” analogous to how S&P 500 index funds work for equities.

Bitwise 10 Crypto Index Fund (BITW) tracks an index of the 10 largest crypto assets, screened and weighted by market cap, rebalanced monthly. BITW was one of the earliest multi-asset crypto products available to US investors and has been publicly traded since 2020 (originally as an OTC product, now as an ETF).

These products solve a real problem for allocators who want “the crypto market” as an asset class without making active decisions about which tokens to own. The index does the work: it holds the largest assets by market cap, rebalances automatically, and gives you broad exposure. The downside is that market-cap weighting means you are heavily concentrated in Bitcoin (typically 60-70% of the index) with smaller allocations to everything else.

The index product explosion. The pace of new crypto ETF filings is accelerating. Beyond single-asset and broad-market products, there are now filings for thematic crypto ETFs covering DeFi, AI tokens, and specific protocol ecosystems. Bitwise’s 11 new strategy ETF filings (December 2025) include products for AAVE, UNI, SUI, TAO, and ZEC, each investing up to 60% in the underlying token with the rest in exchange-traded products and derivatives. We are entering the era of granular and strategy-specific passive crypto exposure.

Private crypto index funds

Before spot ETFs existed, institutional investors accessed passive crypto exposure through private fund structures. Some of these still operate, particularly for strategies that cannot easily be replicated in an ETF wrapper.

Private crypto index funds typically hold a basket of tokens and charge management fees in the 1-3% range (significantly higher than ETFs). They were popular from 2017 through 2023 because they were the only way for institutions to get diversified crypto exposure in a fund structure with a familiar legal wrapper, compliance framework, and reporting format. Many are denominated in specific jurisdictions (Cayman Islands, BVI) and accept only accredited or institutional investors.

With the advent of cheap ETFs, private index funds face an existential challenge. Why pay 2% per year for a private fund that holds the same basket of tokens you can get through an ETF at 0.20%? The answer for some allocators is customization (a private fund can hold tokens not available in any ETF), jurisdiction (non-US investors may prefer Cayman-domiciled products), and minimum investment thresholds (some institutional mandates require private fund structures). But for many allocators, the cost advantage of ETFs is overwhelming. Our Crypto Fund List includes both private index funds and ETFs for comprehensive coverage.

Passive vs. active: what the data shows

In CFR’s data, index/tracker funds have a beta of 0.93 to Bitcoin, the highest of any strategy category. They essentially move with the market. Their Sharpe ratio is approximately 0.70, the lowest of any category (see our strategy comparison for the full breakdown). This means passive crypto exposure delivers the market return minus fees, with no risk management, no hedging, and no alpha.

In bull markets, this is hard to beat. Bitcoin returned 121% in 2024. The average actively managed crypto fund returned approximately 46%. Most active managers underperformed the passive benchmark, just as most active equity managers underperform the S&P 500 in strong bull years. If the market goes straight up, the cheapest way to participate is passive.

In bear markets, the picture reverses. Bitcoin fell 64% in 2022. The average active crypto fund fell 42%. Active management saved approximately 22 percentage points of drawdown through hedging, position sizing, and risk management. In an asset class where drawdowns routinely exceed 50%, that downside protection has enormous compounding value over time.

The honest conclusion: passive is better for pure upside capture at the lowest cost. Active is better for risk-adjusted returns, drawdown protection, and alpha generation. Neither is universally superior. The right choice depends on your risk tolerance, fee sensitivity, and investment horizon. For most institutional allocators, a blend of both makes the most sense.

The core-satellite approach

The most sophisticated institutional approach to crypto allocation is a core-satellite model, borrowed from traditional portfolio construction.

The core (60-70% of crypto allocation): Cheap passive exposure through spot Bitcoin ETFs and/or a multi-asset crypto index product. This gives you broad market exposure at 0.15-0.25% per year. The core captures the market return. It is the beta of your crypto allocation.

The satellites (30-40% of crypto allocation): One to three active managers selected for specific alpha sources. A quant fund for systematic alpha with low beta (see top quant crypto funds). A market-neutral fund for uncorrelated returns (see market-neutral crypto funds). Or a discretionary long/short manager who has demonstrated genuine alpha over a full cycle. The satellites generate excess return and provide risk management that passive cannot.

The core-satellite structure aligns the fee budget with the value delivered. You pay almost nothing for beta (0.20% on the ETF core). You pay meaningful fees (2/20 or equivalent) only for the alpha-generating satellites where the manager is doing something a passive product cannot replicate. This is a more efficient use of fee dollars than putting 100% into expensive active management that may be delivering mostly beta.

To evaluate which active managers deserve satellite allocation, see our manager evaluation guide, strategy comparison, and the Performance Database.

FAQ

What is the cheapest way to get crypto exposure?

As of 2026, the cheapest regulated crypto exposure is through spot Bitcoin ETFs. Grayscale’s BTC Mini Trust charges 0.15% per year. Bitwise’s BITB charges 0.20%. BlackRock’s IBIT charges 0.25%. For diversified multi-asset exposure, Grayscale’s GDLC covers the top five crypto assets. These are all dramatically cheaper than any active crypto fund, which typically charges 1-2% management fees plus 10-20% performance fees.

Should I invest in a crypto index fund or an active fund?

It depends on your goals. If you want maximum upside exposure to crypto at the lowest cost and can tolerate 50-70%+ drawdowns, passive index exposure is hard to beat. If you want risk management, downside protection, or returns that are uncorrelated with Bitcoin’s direction, you need an active manager. Many allocators do both: passive for the core, active for the satellites. See the core-satellite section above for details.

Do crypto index funds hold the actual tokens?

Spot Bitcoin ETFs hold actual Bitcoin through institutional custodians (Coinbase Custody for most, Fidelity Digital Assets for FBTC). Multi-asset index ETFs like GDLC hold the underlying tokens directly. Bitwise’s BITB provides a publicly verifiable proof-of-reserves page. This is physically-backed exposure, not synthetic or futures-based (which was the only option before 2024).

Are there crypto index products beyond BTC and ETH?

Yes, and the number is growing rapidly. GDLC covers BTC, ETH, ADA, XRP, and SOL. BITW covers the top 10 by market cap. Grayscale has single-asset ETFs for SOL, XRP, Dogecoin, and Chainlink. Bitwise has filed for 11 new strategy ETFs covering tokens including AAVE, UNI, SUI, TAO, and ZEC. By the end of 2026, the range of available passive crypto products will be dramatically broader than it is today.

How does CFR track index and tracker funds?

CFR’s database includes index/tracker funds as one of the strategy categories. In our Q4 2025 report, index/tracker funds had the highest beta to Bitcoin (0.93) and the lowest Sharpe ratio of any strategy. We track their performance alongside active strategies to provide the benchmarking context allocators need. The Performance Database lets you compare any active fund against index/tracker performance.
