Investment objective & strategy
As of Jan. 27, 2025 · prospectusObjective. The Grayscale Bitcoin Miners ETF (the Fund) seeks investment results that track the performance (before fees and expenses) of the Indxx Bitcoin Miners Index (the Index).
Strategy. The Fund will not invest in digital assets directly or through the use of derivatives. The Fund also will not invest in initial coin offerings. The Fund may, however, have indirect exposure to digital assets by virtue of its investments in companies that use one or more digital assets as part of their business activities or that hold digital assets as proprietary investments. Because the Fund will not invest directly in any digital assets, it will not track price movements of any digital assets. Under normal circumstances, the Fund will invest at least 80% of its net assets (including investment borrowings) in the constituents that comprise the Index and in other instruments that have economic characteristics and provide investment exposure … The Fund will not invest in digital assets directly or through the use of derivatives. The Fund also will not invest in initial coin offerings. The Fund may, however, have indirect exposure to digital assets by virtue of its investments in companies that use one or more digital assets as part of their business activities or that hold digital assets as proprietary investments. Because the Fund will not invest directly in any digital assets, it will not track price movements of any digital assets. Under normal circumstances, the Fund will invest at least 80% of its net assets (including investment borrowings) in the constituents that comprise the Index and in other instruments that have economic characteristics and provide investment exposure similar to the component securities of the Index. Other instruments that have economic characteristics and provide investment exposure similar to the component securities of the Index include depositary receipts (such as American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs)). The Fund invests in equity securities ( e.g. , common stock) and depositary receipts of companies included in the Index. The Fund uses a passive management (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index is designed by Indxx (the Index Provider) to consist of U.S. and non-U.S. equity securities of companies that have been classified by the Index Provider as providing exposure to global bitcoin mining companies that generate revenue from bitcoin mining activities or mining related hardware, software and/or services (collectively, Bitcoin Mining Companies). In constructing the Index, the Index Provider identifies Bitcoin Mining Companies that are involved in the mining of Bitcoin and verification of the Bitcoin network, Bitcoin mining pool services, and adding Bitcoin transactions into blockchain ledgers. The Index Provider may also include companies that provide Bitcoin mining infrastructure and related services such as data center hosting, the manufacturing of ASICs (Application-Specific Integrated Circuits) machines, mining rigs, and GPUs (Graphics Processing Units), and related hardware and software for bitcoin mining (collectively, Bitcoin Mining). The Index Provider determines eligible Bitcoin Mining Companies based on a proprietary process that relies on extensive research to generate a preliminary list of Bitcoin Mining Companies. To be eligible for inclusion in the initial investable universe, securities must be/have: ? Their listing either in a developed (including the U.S.) or emerging market based on the Index Providers rules-based country classification system, in the form of common stock or depositary receipt (American or global). As of January 2025, the list of developed markets includes the United States, Canada, Australia, Hong Kong, Japan, New Zealand, Singapore, South Korea, Taiwan, Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Israel, Italy, Poland, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom and the list of emerging markets includes Brazil, Chile, Colombia, Mexico, Peru, China, India, Indonesia, Malaysia, Philippines, Thailand, Vietnam, Czech Republic, Greece, Hungary, Kuwait, Qatar, South Africa, Turkey and the United Arab Emirates. ? A minimum total market capitalization of $50 million USD. ? A six-month average daily turnover greater than or equal to $0.5 million. ? All securities must have a minimum free float equivalent to 10% of shares outstanding. ? Securities trading at a price of $10,000 or above are ineligible for inclusion in the Index. This rule is not applicable for existing constituents. Existing constituents shall remain in the initial universe irrespective of their stock price. ? Traded on 90% of the eligible trading days in the last six-months. In the case of initial public offerings where a security does not have a trading history of six-months, such a security must have started trading at least three-months before the start of the reconstitution and rebalancing process and should have traded on 90% of the eligible trading days for the past three-months. The Index Provider further classifies the Bitcoin Mining Companies using the following methodology: ? Pure-Play : Companies that derive greater than or equal to 50% of their revenue from Bitcoin Mining are considered as pure-play companies. ? Quasi-Play: Companies with diversified revenue streams that generate at least 20% (but less than 50%) of their revenue from Bitcoin Mining are considered as quasi-play companies. ? Marginal: Companies with diversified revenue streams that generate less than 20% of their revenue from Bitcoin Mining are considered as marginal companies. In constructing the Index, the Index Provider includes the top 25 Pure-Play companies by market capitalization. If fewer than 25 Pure-Play companies qualify for inclusion in the Index, then the top Quasi-Play companies by largest total market capitalization are included until the portfolio size reaches 25. If fewer than 25 Pure-Play and Quasi-Play companies qualify for inclusion in the Index, then the top Marginal companies by largest total market capitalization are included until the portfolio size reaches 25. If there are fewer than 25 companies in the selection list, all the companies are considered. The Index is reconstituted and rebalanced quarterly after the close of business on the last trading day (Effective Date) of each March, June, September, and December, based on data as of the last week of each month prior to the applicable reconstitution and rebalance period of the Index. The Index is weighted as follows: ? Securities are weighted based on their security level free float market capitalization. ? Total weight of Quasi-Play + Marginal companies is capped at 15%. ? Within the Quasi-Play + Marginal basket a security cap of 3% is applied and the excess weight is redistributed proportionally amongst the uncapped securities within this basket. ? A single security cap of 15% is applied amongst the Pure-Play securities and the excess weight is redistributed proportionally amongst the uncapped securities within this basket. ? Total weight of the securities with weights greater than 5% is capped at 45% and a single cap of 4.25% is applied on the securities thereafter with weights greater than 5% and the excess weight is redistributed proportionally amongst the uncapped securities within the Pure-Play basket. For example, where the Index is comprised completely of Pure-Play companies, a single security cap of 15% is applied and the excess weight is redistributed proportionally among the uncapped securities within the basket. An aggregate cap is then applied such that the total weights of securities with weights greater than 5% is capped at 45%. Following this aggregate cap, securities with weights in excess of 5% are capped to 4.25% and excess weight is redistributed among the remaining uncapped securities. In the event that fewer than 25 Pure-Play companies qualify for inclusion in the Index and Quasi-Play and Marginal companies become eligible, the same process is followed subject to a maximum weight of 15% for the aggregate of all Quasi-Play and Marginal companies. A single security cap of 3% is applied to any given Quasi-Play or Marginal security and the excess weight is redistributed proportionally among the uncapped Quasi-Play or Marginal securities such that the total weight allocated to such companies is capped at 15%. Pure-Play security weighting follows the same capping methodology described above, with a single security cap of 15%, an aggregate cap of 45% for the total allocation of securities greater than 5%, and a final single security cap of 4.25% thereafter. A blockchain is a digital series of records stored across a decentralized network that uses cryptography to create a secure and verified history of transactions. The decentralized nature of a blockchain utilizes and relies on multiple nodes to continuously update and certify the accuracy of information in the chain, mitigating the risks associated with centralized networks, where a single source can be tampered with to change information across a network. Blockchain technology can be used to record transactions involving tangible, intangible, and digital assets, and a blockchain may be constrained to certain users or companies or open to the public. Blockchain networks may also be used to track the purchase, sale, or exchange of digital assets. Digital assets may be considered a form of digital currency that can be used to purchase goods or services from certain vendors or can be purchased or sold like an investment asset. Digital assets generally rely on a blockchain to maintain the integrity of their transaction histories, and new amounts of a digital asset are added to the available supply based on the completion of certain complex mathematical problems a process known as digital asset mining. The Fund generally employs a passive management investment strategy in seeking to achieve its investment objective and fully replicate the Index. However, under various circumstances, the Fund may use a representative sampling strategy, whereby the Fund would invest in what it believes to be a representative sample of the component securities of the Index. The Fund may use a representative sampling strategy when a replication strategy might be detrimental to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of securities to follow the Index; or, in certain instances, when a component security of the Index becomes temporarily illiquid, unavailable or less liquid. The Fund may also use a representative sampling strategy to exclude less liquid component securities contained in the Index from the Funds portfolio in order to create a more tradable portfolio and improve arbitrage opportunities. To the extent the Fund uses a representative sampling strategy, it may not track the Index with the same degree of accuracy as would an investment vehicle replicating the entire Index. The Fund may invest in small-, mid- and large-capitalization companies. The Fund may lend securities representing up to one-third of the value of the Funds total assets (including the value of the collateral received). The Fund is non-diversified under the Investment Company Act of 1940, as amended (1940 Act), and therefore is not required to meet certain diversification requirements under the 1940 Act. Concentration Policy . The Fund may concentrate its investments ( i.e. , invest 25% or more of the value of its total assets) in a particular industry or group of industries to the extent that the Index concentrates in an industry or group of industries. As of December 31, 2024, the Index had approximately 26 constituents and significant exposure to the Information Technology sector. The Funds portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time.
