Important Notice:

The Company holds cryptocurrencies or cryptoassets. Whilst the Board of Directors of the Company considers holding cryptocurrencies to be in the best interests of the Company, the Board remains aware that the financial regulator in the UK (the Financial Conduct Authority or FCA) considers investment in cryptocurrencies to be high risk. At the outset, it is important to note that an investment in the Company is not an investment in cryptocurrencies, either directly or by proxy and shareholders will have no direct access to the Company's holdings. However, the Board of Directors consider cryptocurrencies to be an appropriate store of value and potential growth and therefore appropriate for the Company. Accordingly, the Company is and intends to continue to be materially exposed to cryptocurrencies. 

The Company is neither authorised nor regulated by the FCA, and the purchase of certain cryptocurrencies are generally unregulated in the UK. As with most other investments, the value of cryptocurrencies can go down as well as up, and therefore the value of the Company's cryptocurrencies holdings can fluctuate. The Company may not be able to realise its cryptocurrencies holdings for the same as it paid to acquire them or even for the value the Company currently ascribes to its cryptocurrencies positions due to market movements. Neither the Company nor investors in the Company's shares are protected by the UK's Financial Ombudsman Service or the Financial Services Compensation Scheme.

Cryptocurrencies may present special risks to the Company's financial position. These risks include (but are not limited to): (i) the value of cryptocurrencies can be highly volatile, with value dropping as quickly as it can rise. Investors in cryptocurrencies must be prepared to lose all money invested in cryptocurrencies; (ii) the cryptocurrencies market is largely unregulated. There is a risk of losing money due to risks such as cyber-attacks, financial crime and counterparty failure; (iii) the Company may not be able to sell its cryptocurrencies at will. The ability to sell cryptocurrencies depends on various factors, including the supply and demand in the market at the relevant time. Operational failings such as technology outages, cyber-attacks and comingling of funds could cause unwanted delay; and (iv) cryptoassets are characterised in some quarters by high degrees of fraud, money laundering and financial crime. Prospective investors in the Company are encouraged to do their own research before investing.
