Cryptocurrencies are no longer a niche financial experiment—they’re a rapidly maturing asset class attracting both retail and institutional investors. As of 2025, the global crypto market continues to evolve with increasing trading volumes, sophisticated financial instruments, and growing demand for passive investment tools. Among these tools, automated cryptocurrency index funds stand out as a smart, efficient way to gain diversified exposure without the complexity of managing individual assets.
Whether you're new to digital assets or an experienced investor seeking streamlined portfolio management, crypto index funds offer a compelling solution. These funds automate rebalancing, reduce emotional trading decisions, and provide access to a basket of top-performing cryptocurrencies—all while minimizing fees and administrative overhead.
In this guide, we’ll explore what cryptocurrency index funds are, how they work, and highlight the four best automated options available today. We’ll also answer common questions and help you decide which fund aligns best with your investment goals.
What Is a Cryptocurrency Index Fund?
An index fund in traditional finance—like the S&P 500—mirrors the performance of a specific market index by holding a diversified portfolio of assets. Similarly, a cryptocurrency index fund tracks a basket of digital assets based on predefined criteria such as market capitalization, liquidity, or algorithmic ranking.
These funds automatically rebalance on a set schedule (weekly, monthly, etc.), ensuring your portfolio stays aligned with current market conditions. This automation removes the need for constant monitoring and manual trading—a major advantage in the volatile and 24/7 crypto market.

Key benefits include:
- Diversification: Reduce risk by spreading investments across multiple high-quality cryptocurrencies.
- Lower fees: Many crypto index funds charge significantly less than actively managed funds.
- Transparency: Most operate on blockchain networks, allowing real-time tracking of holdings.
- Ease of use: Buy one token or make one investment to gain exposure to dozens of assets.
Now, let’s dive into the top four automated cryptocurrency index funds reshaping passive investing in 2025.
1. Crypto20 (C20)
Crypto20, often abbreviated as C20, was one of the first tokenized crypto index funds built on the Ethereum blockchain as an ERC-20 token. It provides exposure to the top 20 cryptocurrencies by market cap, automatically rebalanced every week.
This fund is ideal for investors who want hands-off access to a broad range of leading digital assets without managing multiple wallets or exchanges.
Key Features:
- Automated Weekly Rebalancing: Ensures the portfolio reflects current market rankings.
- Low Annual Fee: Just 0.5%, making it one of the most cost-effective options.
- 24/7 Trading: C20 tokens can be traded anytime on major exchanges with no exit fees.
- Full Transparency: All underlying transactions are visible on the blockchain.
- Fork Protection: Automatically includes new tokens from hard forks and adjusts allocations accordingly.
Investors benefit from simplicity—just buy the C20 token and hold. The fund’s smart contract handles everything else, including a built-in liquidation feature that allows redemption in ETH based on your share of the underlying assets.
Crypto20 appeals to both beginners and seasoned traders looking for a low-maintenance, diversified strategy.
2. Cryptoindex (CIX100)
Cryptoindex offers the CIX100, an AI-driven index fund tracking the top 100 cryptocurrencies. Powered by Zorax’s proprietary algorithm, this fund analyzes over 200 data points—including market performance, community engagement, and price manipulation risks—to select and rank assets.
Unlike simpler market-cap-weighted indexes, CIX100 uses advanced analytics to filter out inflated or low-quality projects.
Standout Advantages:
- Monthly Rebalancing: Keeps the portfolio up-to-date with market dynamics.
- Sector-Based Indexes: Offers specialized indexes in areas like decentralized storage, supply chain, and advertising.
- Bloomberg & Reuters Integration: The CIX100 index is available on professional financial terminals, signaling growing institutional acceptance.
- ERC-20 Token (CIX100): Easy to buy, store, and trade like any other crypto asset.
While Cryptoindex is more suited for advanced users due to its analytical depth and trading platform features, it also allows users to build custom portfolios based on its indexes—adding flexibility beyond passive tracking.
Its AI-powered approach makes it a strong contender for investors seeking data-driven diversification.
