Concentration Risk [Abstract] |
Concentration Risk | Note 7. Concentration Risk Substantially all of the Trust’s assets are holdings of ETH, which creates a concentration risk associated with fluctuations in the value of ETH due to a number of factors. Accordingly, a decline in the value of ETH will have an adverse effect on the value of the Shares of the Trust. Factors that may have the effect of causing a decline in the value of ETH include high volatility, which could have a negative impact on the performance of the Trust. ETH platforms are relatively new and may be unregulated or may be subject to regulation in a relevant jurisdiction, but may not be complying, and therefore, may be more exposed to fraud and security breaches than established, regulated exchanges for other financial assets or instruments, which could have a negative impact on the performance of the Trust. The value of the Shares depends on the development and acceptance of the ethereum network. The slowing or stopping of the development or acceptance of the ethereum network may adversely affect an investment in the Trust. The price of ETH on the ETH market has exhibited periods of extreme volatility. Digital assets such as ETH were only introduced within the past decade, and the medium-to-long term value of the Shares is subject to a number of factors relating to the capabilities and development of block-chain technologies and to the fundamental investment characteristics of digital assets that are uncertain and difficult to evaluate. The Trust is subject to risks due to its concentration of investments in a single asset class. Possible illiquid markets may exacerbate losses or increase the variability between the Trust’s NAV and its market price. The amount of ETH represented by the Shares may decline over time. ETH with a fair value of $157,608,454 and $146,428,902 were held by the ETH Custodians at December 31, 2025 and December 31, 2024, respectively. Future and current regulations by a United States or foreign government or quasi-governmental agency could have an adverse effect on an investment in the Trust. Shareholders do not have the protections associated with ownership of Shares in an investment company registered under the 1940 Act or the protections afforded by the Commodity Exchange Act. Future legal or regulatory developments may negatively affect the value of ETH or require the Trust or the Sponsor to become registered with the SEC or CFTC, which may cause the Trust to liquidate. The Exchange on which the Shares are listed may halt trading in the Trust’s Shares, which would adversely impact a Shareholder’s ability to sell Shares. The market infrastructure of the ETH spot market could result in the absence of active authorized participants able to support the trading activity of the Trust. Shareholders that are not authorized participants may only purchase or sell their Shares in secondary trading markets, and the conditions associated with trading in secondary markets may adversely affect Shareholders’ investment in the Shares.
