Cryptocurrency exchange-traded funds (ETFs) have emerged as a popular gateway for traditional investors to gain exposure to blockchain technology and digital assets—without directly owning cryptocurrencies like Bitcoin or Ethereum. These ETFs invest in companies that develop, use, or benefit from blockchain technology, offering diversified, regulated, and accessible investment opportunities.
With the growing interest in blockchain-driven innovation, selecting the right cryptocurrency ETF requires careful evaluation. Key factors include management fees, portfolio diversity, underlying index methodology, and the credibility of the fund provider. In this guide, we’ll explore the top-performing crypto-related ETFs, their structures, and what makes them stand out in a rapidly evolving market.

Understanding Cryptocurrency ETFs
A cryptocurrency ETF doesn’t typically hold digital coins directly. Instead, it tracks companies involved in blockchain infrastructure, cryptocurrency mining, digital asset platforms, or financial technology innovations tied to decentralized systems. This indirect exposure allows investors to participate in the growth of the crypto ecosystem through familiar stock market instruments.
The best cryptocurrency ETFs are built on transparent indices, maintain low expense ratios, and offer broad exposure across market capitalizations and geographies. They also prioritize companies with tangible involvement in blockchain—not just speculative associations.
Let’s examine three leading blockchain-focused ETFs that have demonstrated strong performance and strategic positioning.
Amplify Transformational Data Sharing ETF (BLOK)
The Amplify Transformational Data Sharing ETF (BLOK) is one of the most recognized names in the blockchain ETF space. It allocates at least 80% of its assets to companies actively engaged in blockchain development and data-sharing technologies.
As of mid-2021, BLOK managed over $1 billion in assets under management (AUM), reflecting strong investor confidence. The fund holds 44 companies, with a balanced mix of large-cap dominance and smaller-cap innovation. Its annual expense ratio stands at 0.71%, which is competitive within the thematic ETF category.
Notable holdings include:
- MicroStrategy Inc. – Known for its aggressive Bitcoin treasury strategy.
- Square Inc. (now Block, Inc.) – A fintech leader integrating Bitcoin into payment systems.
- PayPal Inc. – Offering crypto buying, selling, and transfer services to millions.
BLOK delivered an impressive 195% one-year return as of June 2021, driven by bullish sentiment around blockchain adoption and institutional crypto investment.
This ETF is ideal for investors seeking concentrated exposure to U.S.-based tech innovators shaping the future of decentralized finance and digital ownership.
First Trust Indxx Innovative Transaction and Process ETF (LEGR)
The First Trust Indxx Innovative Transaction and Process ETF (LEGR) tracks the Indxx Blockchain Index, which includes global companies developing or benefiting from blockchain solutions. The fund invests at least 90% of its assets in these firms, ensuring high thematic purity.
With more than 100 holdings, LEGR offers broader diversification compared to other blockchain ETFs. Its net assets were valued at approximately $117.7 million, with an attractive expense ratio of 0.65%—slightly lower than BLOK.
Top contributors to the portfolio include:
- NVIDIA Corporation – Supplying GPUs critical for blockchain computation and mining.
- Microsoft Corporation – Integrating blockchain into cloud services via Azure.
- Oracle Corporation – Developing enterprise-grade distributed ledger solutions.
- Capgemini SE – A global consultant implementing blockchain in supply chains and finance.
LEGR’s methodology emphasizes real-world application over hype, focusing on firms with active R&D or commercial deployment of blockchain tech. This makes it a solid choice for long-term investors who value fundamentals over short-term volatility.

Reality Shares Nasdaq NexGen Economy ETF (BLCN)
The Reality Shares Nasdaq NexGen Economy ETF (BLCN) follows the Nasdaq Blockchain Economy Index, tracking companies driving innovation across the blockchain value chain—from infrastructure to applications.
With around 74 holdings, BLCN strikes a balance between diversification and focus. Its total net assets reached $284.63 million, and it charges an expense ratio of 0.68%.
One of BLCN’s standout features is its strict weighting cap: no single holding exceeds 2% of the portfolio. This prevents overreliance on any one company and spreads risk evenly across sectors such as fintech, cybersecurity, cloud computing, and digital currency platforms.
Key constituents include:
- Coinbase Global Inc. – One of the largest regulated crypto exchanges in the U.S.
- Accenture Plc – A consulting giant helping enterprises adopt blockchain solutions.
- Square Inc. – Again featured due to its deep integration with crypto payments.
This equal-weight-like structure enhances resilience during market swings and supports consistent performance over time.
Emerging Trends and Future Outlook
While these three ETFs lead the current landscape, new products continue to enter the market—especially as regulators warm up to spot Bitcoin ETFs. Products like Koin and early movers such as BTTC, touted as the world’s first Bitcoin ETF in certain regions, signal growing institutional acceptance.
However, investors should remain cautious about funds with unclear mandates or excessive concentration in volatile small-cap stocks. Always assess:
- Index construction methodology
- Geographic and sector diversification
- Historical performance relative to benchmarks
- Regulatory compliance and transparency
As blockchain moves beyond speculation into real-world utility—from supply chain tracking to tokenized assets—the strongest ETFs will be those rooted in measurable impact and sustainable business models.
