Note 7. Concentration Risk

Substantially all of the Trust’s assets are holdings of bitcoin, which creates a concentration risk associated with fluctuations in the value of bitcoin due to a number of factors. Accordingly, a decline in the value of bitcoin 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 bitcoin include high volatility, which could have a negative impact on the performance of the Trust. Bitcoin 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 bitcoin network. The slowing or stopping of the development or acceptance of the bitcoin network may adversely affect an investment in the Trust. The price of bitcoin on the bitcoin market has exhibited periods of extreme volatility. Digital assets such as bitcoin 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.
