A spot Bitcoin ETF gives you BTC, full stop. A crypto index ETF holds a basket — around three-quarters of which is bitcoin anyway. Here is when each makes sense.
TL;DR. The US has had spot crypto index ETFs since early 2025. BITW, NCIQ, EZPZ and GDLC trade on US exchanges and hold the coins themselves. Fees run from 0.19% to 0.75%, against 0.25% for IBIT, so most of them cost more than a Bitcoin ETF. And they are mostly bitcoin anyway: BTC is three-quarters or more of each basket. If you want bitcoin, buy a Bitcoin ETF. If you want the smaller coins in one ticker and don't want to manage them yourself, an index ETF does that at a tolerable price.

The US spot crypto index ETFs
| Ticker | Fund | Exchange | Fee | Assets | Launched |
|---|---|---|---|---|---|
| BITW | Bitwise 10 Crypto Index ETF | NYSE Arca | 0.75% | ~$775M | Trust since 2017, uplisted 2025 |
| NCIQ | Hashdex Nasdaq CME Crypto Index ETF | Nasdaq | 0.25% | ~$505M | 13 Feb 2025 |
| EZPZ | Franklin Crypto Index ETF | Cboe BZX | 0.19% | ~$16M | 20 Feb 2025 |
| GDLC | Grayscale CoinDesk Crypto 5 ETF | NYSE Arca | 0.59% | ~$442M | Trust since 2018, uplisted 2025 |
Figures as of 24 September 2026. All four hold the coins directly, and none of them uses futures. NCIQ says so in its own disclosure: the fund "invests directly in the crypto assets and will not utilize leverage and derivatives."
The basket is mostly bitcoin
For most people, this settles it. BITW's holdings on 22 September 2026:
- Bitcoin 75.66%
- Ether 14.51%
- XRP 4.34%
- Solana 3.00%
- Hyperliquid 0.95%
- Cardano, Chainlink, Stellar, Litecoin and Sui: 1.5% between them
EZPZ is similar: 76.78% bitcoin, 12.62% ether, 5.34% XRP, 3.62% solana. GDLC holds only the five largest assets: bitcoin, ether, solana, BNB and XRP. When one coin dominates the market this much, weighting by market cap gives you little diversification. What you get is a Bitcoin ETF with a 20-25% satellite bolted on.
The structural differences
| Dimension | Bitcoin ETF (IBIT) | Crypto index ETF (BITW) |
|---|---|---|
| Asset exposure | 100% bitcoin | ~76% BTC, rest across nine assets |
| Expense ratio | 0.25% | 0.75% |
| Structure | Exchange-traded product | Exchange-traded product |
| Rebalancing | None — single asset | Index rebalances; weights drift with prices |
| Tax wrappers | Any brokerage account, IRA, 401(k) | Same — it is a listed ETF |
| What you are buying | A view on bitcoin | A view on "crypto as an asset class" |
The bitcoin-specific case
If you are buying bitcoin as a monetary asset, the rest of the basket is dead weight. The non-bitcoin quarter is a separate bet that moves for its own reasons. Inside an index fund you can't size it yourself or drop the coins you don't believe in. The full argument for the single-asset wrapper is in Bitcoin ETF vs spot Bitcoin.
The diversified case, and the build-your-own alternative
Say you want crypto as a whole, not just bitcoin. An index ETF gives you one ticker, weights that adjust without your help, and coins that have no US ETF of their own. EZPZ at 0.19% costs less than IBIT and is the cheapest way to own that basket.
The alternative is to assemble it: a spot Bitcoin ETF for the core, a spot Ethereum ETF for ether, and the spot Solana and XRP ETFs that have traded since late 2025 for the next two. The blended fee ends up in the same range. You pick the weights and rebalance when you decide to. You lose the tail: the tenth-largest asset in BITW is 0.17% of the fund and has no US ETF of its own.

FAQ
What's the difference between a Bitcoin ETF and a crypto index fund?
A spot Bitcoin ETF holds only bitcoin. A crypto index ETF holds a basket weighted by market cap. In practice that is around three-quarters bitcoin, 13-15% ether, and single-digit weights in XRP, solana and a few others. Both kinds are listed ETFs that hold the coins directly. The index products charge between 0.19% and 0.75%.
Is BITW a Bitcoin ETF?
No. BITW is the Bitwise 10 Crypto Index ETF, holding the ten largest crypto assets by market cap. Bitcoin was 75.66% of it on 22 September 2026, with ether at 14.51% and eight smaller positions making up the rest. It trades on NYSE Arca and charges 0.75%.
Should I buy a Bitcoin ETF or a crypto index fund?
If you want bitcoin, buy the Bitcoin ETF. The index funds are mostly bitcoin anyway, and three of the four charge the same as IBIT or more. An index fund makes sense only if you specifically want the smaller coins and don't want to hold four or five tickers to get them.
Why is BITW's fee higher than a Bitcoin ETF's?
BITW charges 0.75% against 0.25% for IBIT. A basket of coins costs more to run than one coin: it needs several custody arrangements, an index license and periodic rebalancing. The cheapest crypto index ETF, Franklin's EZPZ at 0.19%, actually costs less than the big Bitcoin ETFs.
Are there spot crypto index ETFs available in the US?
Yes, at least four. Hashdex's NCIQ (February 2025) and Franklin's EZPZ (February 2025) launched as ETFs. Grayscale's GDLC and Bitwise's BITW were existing trusts that uplisted to US exchanges during 2025. All four hold the coins directly; none uses futures.
