Crypto ETFs: The Complete Guide to On-Chain Investing
What Are ETFs?
Exchange-Traded Funds (ETFs) revolutionized traditional investing by making diversification simple and affordable. Instead of buying hundreds of individual stocks to match the S&P 500, investors can buy a single fund that holds all those companies automatically.
ETFs track a market benchmark—like the S&P 500, Nasdaq-100, or any sector—by holding the same assets in the same proportions. This passive investment strategy has proven remarkably effective:
- Simplicity: One purchase gets you instant diversification
- Consistent performance: Most active managers fail to beat ETFs over time
- Tax efficiency: Less trading means fewer taxable events
- Liquidity: Trade anytime during market hours like a stock
The Rise of Crypto ETFs
In 2024, the cryptocurrency market reached a major milestone with the approval of Bitcoin and Ethereum spot ETFs in the United States. This regulatory green light opened crypto investing to millions of traditional investors who wanted exposure without the complexity of self-custody.
How Crypto ETFs Work
Crypto ETFs function like traditional ETFs but track digital assets instead of stocks or bonds:
- Spot crypto ETFs hold actual cryptocurrencies (like Bitcoin or Ethereum)
- Futures-based ETFs use derivative contracts to track crypto prices
- Multi-asset crypto ETFs hold baskets of different cryptocurrencies
Popular crypto ETFs include:
- Single-asset funds (IBIT for Bitcoin, FETH for Ethereum)
- Diversified crypto funds (GDLC holds Bitcoin, Ethereum, XRP, Solana, and Cardano)
- Leveraged and inverse funds for active traders
Why Crypto ETFs Became Popular
Crypto ETFs solved several key problems for traditional investors:
- Accessibility: Buy crypto through your existing brokerage account
- Security: Professional custodians handle storage and security
- Familiarity: Works like any other ETF you already own
- Regulatory comfort: SEC-approved investment vehicles
- Tax simplicity: Standard 1099 forms instead of complex crypto tax reporting
The Limitations of Traditional Crypto ETFs
Despite their popularity, traditional crypto ETFs come with significant drawbacks that limit their potential:
Centralization Risk
Traditional ETFs require trusting centralized institutions:
- Custody risk: Your crypto is held by third-party custodians
- Counterparty risk: The fund manager could face regulatory or operational issues
- Limited transparency: Holdings are disclosed periodically, not in real-time
High Fees Eating Returns
ETF expense ratios might seem small, but they compound significantly:
- Average crypto ETF fees: 0.20% - 0.95% annually
- A 0.50% annual fee may seem small, but compounds significantly over time
- Management fees, custody fees, and trading costs all add up
Trading Restrictions
Traditional ETFs operate within market hours:
- Trade only when stock exchanges are open (9:30 AM - 4:00 PM ET, Monday-Friday)
- Miss crypto market movements on weekends and holidays
- Can't respond to 24/7 crypto volatility
No Direct Ownership
With traditional crypto ETFs, you don't actually own the underlying cryptocurrency:
- Can't transfer your crypto to a wallet
- Can't use your holdings in DeFi protocols
- Limited to price exposure only
On-Chain ETFs: The Next Evolution
On-chain crypto ETFs combine the best features of traditional ETFs with the power of blockchain technology. These decentralized products offer everything traditional ETFs provide—plus crucial advantages that only blockchain makes possible.

Introducing Bundles: On-Chain ETFs for Everything
Bundles is the first protocol for creating and investing in fully on-chain automated ETFs. Think of it as the infrastructure layer for decentralized index funds—where anyone can create an ETF for any tokenized asset, and anyone can invest with a single transaction.
Beyond Crypto: ETFs for Every Asset Class
While Bundles started with crypto-native indexes, the protocol supports any ERC-20 token—which means any tokenized asset. This opens up possibilities that traditional ETFs can't match:
Tokenized Real World Assets (RWAs)
- Equities & ETFs: Tokenized company shares and market indices (e.g., Tesla, Apple, S&P 500 tokens)
- Real Estate: Fractionalized property exposure through tokenized real estate
- Private Markets: Access to pre-IPO companies and venture investments
Commodities & Precious Metals
- Gold & Silver: Tokenized precious metals (PAXG, XAUT)
- Energy: Oil, gas, electricity as tokenized instruments
- Agricultural: Wheat, corn, soy, and other commodity exposure
Custom Strategies
- Geographic indexes: European tech, Asian markets, emerging economies
- Sector-specific: AI companies, renewable energy, biotech
- Thematic: ESG-focused, dividend-paying, growth stocks
With Bundles, you can create a globally diversified portfolio combining crypto, stocks, real estate, and commodities—all in one on-chain token, all self-rebalancing, all available 24/7.

How Bundles Works
Bundles are fully on-chain ETFs that hold multiple assets with target weights. Instead of manual rebalancing or fixed schedules, Bundles uses a threshold system:
- Set target weights: Each asset has a target percentage (e.g., 40% BTC, 40% ETH, 15% USDC, 5% BUN)
- Define thresholds: Assets can drift within a range before rebalancing triggers
- Automatic execution: When an asset moves beyond its threshold, the ETF rebalances automatically
The Performance Advantage: Threshold Rebalancing
Traditional ETFs rebalance on fixed schedules (monthly, quarterly). Bundles rebalances based on market movements:
When assets outperform:
- Price increases push the asset above its target weight
- ETF automatically sells the outperformer
- Takes profits at market highs
When assets underperform:
- Price decreases push the asset below its target weight
- ETF automatically buys more
- Accumulates at market lows
This systematic "buy low, sell high" approach captures value from volatility that buy-and-hold strategies miss—all executed automatically by smart contracts.
Real Example: $CORE bundle
The $CORE bundle demonstrates this strategy with crypto's foundation assets:
- 40% Bitcoin (BTC) - Digital gold and store of value
- 40% Ethereum (ETH) - Smart contract platform
- 15% USDC - Stablecoin for stability
- 5% BUN - Protocol token for rebalancing fees
With a 5% threshold, when BTC surges and reaches 45% of the portfolio, the ETF automatically sells the excess and rebalances into underweight assets. When volatility reverses, it's already positioned to capture the next move.

The Future of Crypto ETFs
The evolution from traditional ETFs to on-chain ETFs represents more than just a technological upgrade—it's a fundamental shift in how we think about diversified investing.
Traditional ETFs brought passive investing to stocks and bonds, making diversification accessible to everyone. They lowered costs and simplified investing, but remained tied to centralized infrastructure and market hours.
Crypto ETFs extended this model to digital assets, offering regulated exposure through familiar channels. But they inherited the limitations of traditional finance: centralization, custody risk, market hours, and high fees.
On-chain ETFs complete the vision: truly decentralized, fully transparent, 24/7 accessible portfolios that give investors direct ownership while capturing the benefits of automated, intelligent rebalancing.
As the crypto market matures and more assets become tokenized (real estate, commodities, equities), on-chain ETFs will expand beyond native crypto to create globally diversified portfolios—accessible to anyone, anywhere, at any time.
