The fund provides exposure to the price of Bitcoin in exchange for Canadian dollars. As shares of the ETF are purchased, the proceeds are used to purchase bitcoin from Fidelitys selected liquidity providers. The price of bitcoin is taken from a variety of sources in order to determine a value for the ETF shares. Once purchased, the bitcoin is then stored in Fidelitys Digital Asset Services, serving as the sub-custodian. Holding bitcoin in an ETF wrapper provides a more efficient way to hold and trade the asset. However, shares of the ETF can not be redeemed for physical bitcoin. While the price of bitcoin will fluctuate 24 hours a day, trading of the ETF shares is also limited to exchange trading hours and listing requirements. Bitcoin is a part of a new an rapidly changing industry, subject to a variety of factors that are difficult to evaluate. Bitcoin has been highly volatile and may not be suited for all investors.
