Key Takeaways
- Focusing on only bitcoin and ether can mean missing opportunities across crypto. The CoinDesk 20 Index includes 20 of the largest and most liquid crypto assets.
- Market-cap weighting concentrates crypto portfolios in bitcoin and ether. The CoinDesk 20 Index limits that concentration, giving other cryptocurrencies a larger role.
- KRYP is the first and only ETF designed to target the performance of the CoinDesk 20 Index.
Why crypto investors may look beyond bitcoin and ether
The cryptocurrency market is growing rapidly, with new technologies and networks emerging across the ecosystem everyday. While bitcoin and ether remain the most widely known crypto assets, the broader crypto market now includes many other cryptocurrencies serving a wide range of uses and applications. For investors seeking exposure to this evolving asset class, focusing on one or a few cryptocurrencies can mean missing opportunities across the broader market.
The CoinDesk 20 Index was designed to provide diversified* exposure to the crypto asset class through a rules-based index of 20 of the largest and most liquid cryptocurrencies. The index excludes memecoins, stablecoins, and certain other crypto assets to focus on the investable crypto market, and it reconstitutes quarterly to capture changes in the market.
ProShares CoinDesk 20 Crypto ETF (Ticker: KRYP) is the first and only ETF[1] designed to target the performance of the CoinDesk 20 Index, offering exposure to the most crypto assets in any ETF[2].
KRYP invests in cryptocurrency derivatives and does not directly invest in cryptocurrency. There is no guarantee the fund will meet its investment objective.
How the CoinDesk 20 Index addresses concentration in crypto
One of the defining characteristics of the cryptocurrency market is how top-heavy it is. Bitcoin and ether represent a large share of total crypto market capitalization. In a traditional market-cap-weighted index, this concentration would result in a portfolio dominated by just these two assets.
The CoinDesk 20 Index addresses this through a modified market capitalization weighting methodology. The index applies a:
- 30% cap on the largest constituent
- 20% cap on all other constituents
This limits concentration in a single crypto asset and allows other major cryptocurrencies to play a larger role in the index. This structure meaningfully changes how exposure is distributed across constituents.

Right: ProShares hypothetical calculation using the CoinDesk 20 Index constituents, weighted by market capitalization without the index caps, as of 6/30/26. For illustrative purposes only.
Without these caps, the index would largely reflect the performance of bitcoin and ether alone. By limiting concentration in the largest assets, the CoinDesk 20 Index creates more balanced exposure across a wider set of cryptocurrencies.
For investors seeking more diversified exposure to the cryptocurrency market, KRYP offers a unique approach—broad crypto exposure with caps in place to reduce concentration in the largest coins.
