TLTR:
The Fund seeks to provide capital appreciation primarily through managed exposure to bitcoin futures contracts. The Fund does not invest directly in bitcoin.
If the Fund is unable to obtain the desired exposure ... the Fund may invest in equity securities of “bitcoin-related companies.
Not-to-be-missed Risks:
Largely unregulated marketplace: Bitcoin, the Bitcoin Network and the bitcoin trading venues are relatively new and, in most cases, largely unregulated. As a result of this lack of regulation, individuals, or groups may engage in insider trading, fraud or market manipulation with respect to bitcoin.
Declining mining compensation: ... If this compensation is not sufficient to incentivize miners to process transactions, the confirmation process for transactions may slow and the Bitcoin Network may become more vulnerable to malicious actors.
Environmental risk: Bitcoin mining currently requires computing hardware that consumes large amounts of electricity... Public perception of the impact of bitcoin mining on climate change may reduce demand for bitcoin and increase the likelihood of regulation that limits bitcoin mining or restricts energy usage by bitcoin miners (recently in China).
