Grayscale Investments, a leading name in digital currency asset management, has announced the launch of a new exchange-traded fund (ETF) focused on Bitcoin mining companies. The Grayscale Bitcoin Miners ETF, trading under the ticker symbol MNRS, offers investors a way to gain exposure to the performance of major Bitcoin mining firms without directly holding cryptocurrency.
This passively managed fund tracks a rules-based index composed of equities from top players in the Bitcoin mining sector. It is designed to provide a streamlined investment vehicle that reflects the growth and evolution of Bitcoin’s infrastructure ecosystem.
What Is the Grayscale Bitcoin Miners ETF (MNRS)?
The Grayscale Bitcoin Miners ETF (MNRS) is an exchange-traded fund that provides investors with exposure to a basket of stocks from leading Bitcoin mining companies. It is structured as a passively managed product, meaning it aims to replicate the performance of a specific index rather than relying on active stock selection.
The fund is designed to capture the potential growth of the Bitcoin network by investing in companies that contribute significant computational power to secure and maintain the blockchain. This allows investors to indirectly benefit from Bitcoin’s appreciation and network expansion.
MNRS began trading on the NYSE on January 30, 2025, with an initial price of $25.31 per share. The fund is rebalanced periodically to reflect changes in the mining industry and ensure it continues to represent the most relevant companies in the sector.

Key Holdings and Portfolio Composition
The MNRS ETF holds stocks from 25 Bitcoin mining companies and large technology firms involved in Bitcoin operations. The portfolio is weighted based on market capitalization and other factors, with the largest allocations going to industry leaders.
Major holdings include Marathon Digital Holdings (MARA) and Riot Platforms (RIOT), which account for 16.66% and 11.92% of the portfolio, respectively. Other significant companies in the fund include Core Scientific, CleanSpark, Iris Energy, Hut 8, and Northern Data AG. Together, these firms represent a substantial portion of the fund’s underlying assets.
This concentration reflects the current landscape of the Bitcoin mining industry, where a few large players control significant portions of the global hash rate. By investing in these companies, the ETF provides exposure to both established miners and emerging innovators in the sector.
Why Invest in a Bitcoin Miners ETF?
Investing in a Bitcoin Miners ETF offers several advantages over direct cryptocurrency ownership or individual stock selection. It provides instant diversification across multiple companies, reducing the risk associated with any single firm’s performance.
Additionally, the ETF structure offers convenience and accessibility through traditional brokerage accounts, making it easier for mainstream investors to participate in the crypto ecosystem. Investors can benefit from Bitcoin’s potential upside without dealing with digital wallets, private keys, or cryptocurrency exchanges.
The performance of mining companies is often leveraged to Bitcoin’s price movements, meaning they may outperform during bull markets but also face increased volatility during downturns. This ETF allows investors to capture this potential while managing risk through diversification.
Bitcoin Mining Industry Growth and Hash Rate Analysis
The Bitcoin mining industry has experienced remarkable growth over the past year. Bitcoin's hash rate, which measures the total computational power dedicated to mining and securing the network, reached an all-time high of over 863 exahashes per second (EH/s) in early 2025.
This represents nearly a 100% increase since early 2024, indicating substantial expansion in mining infrastructure and capability. The growing hash rate reflects increased miner activity and confidence in Bitcoin's long-term value proposition.
Several factors have contributed to this growth, including improved mining hardware efficiency, expanding renewable energy integration in mining operations, and overall network security enhancements. This growth trajectory suggests a robust and maturing industry that continues to attract significant investment.
Frequently Asked Questions

The Grayscale Bitcoin Miners ETF (MNRS) is an exchange-traded fund that invests in a portfolio of stocks from companies primarily engaged in Bitcoin mining. It offers investors exposure to the Bitcoin ecosystem without directly holding cryptocurrency.
How does MNRS differ from holding Bitcoin directly?
MNRS provides exposure to companies that benefit from Bitcoin's growth rather than holding Bitcoin itself. This approach offers diversification across multiple firms and avoids the technical challenges of direct cryptocurrency ownership while still capturing potential upside from Bitcoin's ecosystem growth.
What are the risks of investing in a Bitcoin miners ETF?
The fund carries risks including Bitcoin price volatility, regulatory changes, technological shifts in mining, and company-specific operational risks. Mining companies may be more volatile than Bitcoin itself due to operational leverage and capital intensity.
Who should consider investing in MNRS?
This ETF may appeal to investors seeking exposure to Bitcoin's infrastructure growth without direct cryptocurrency ownership. It's suitable for those comfortable with equity market risks and interested in the blockchain technology ecosystem.
How is the ETF's portfolio weighted and rebalanced?
The fund tracks a rules-based index weighted by factors including market capitalization. It undergoes periodic rebalancing to reflect changes in the mining industry and ensure appropriate representation of leading companies.
Does the ETF pay dividends?
Whether MNRS pays dividends depends on the dividend policies of its underlying holdings. Many mining companies reinvest profits into expanding operations rather than paying dividends, so investors should primarily expect capital appreciation rather than income distribution.
Investment Considerations and Market Outlook
The launch of MNRS represents another milestone in the integration of cryptocurrency-related investment products into traditional finance. It follows the successful introduction of spot Bitcoin ETFs and reflects growing institutional interest in Bitcoin's infrastructure ecosystem.
For investors considering this ETF, it's important to understand that mining company stocks can be more volatile than Bitcoin itself. These companies face unique risks including regulatory changes, energy cost fluctuations, technological obsolescence, and operational challenges.
However, for those bullish on Bitcoin's long-term prospects, the miners ETF offers a potentially rewarding way to gain leveraged exposure to Bitcoin's price movements while investing in companies with tangible assets and revenue streams.
The continued growth of Bitcoin's hash rate and the expansion of mining operations globally suggest a healthy and competitive industry. As Bitcoin continues to evolve, mining companies are likely to play an increasingly important role in network security and development.
