 organized groups and individuals, including state actors. The techniques
used to obtain unauthorized, improper or illegal access to systems and information (including personal data and digital assets), disable
or degrade services, or sabotage systems are constantly evolving, may be difficult to detect quickly, and often are not recognized or
detected until after they have been launched against a target. These attacks may occur on our systems or those of our third-party service
providers or partners. We may experience breaches of our security measures due to human error, malfeasance, insider threats, system errors
or vulnerabilities or other irregularities. In particular, we expect that unauthorized parties will attempt, to gain access to our systems
and facilities, as well as those of our partners and third-party service providers, through various means, such as hacking, social engineering,
phishing and fraud. Threats can come from a variety of sources, including criminal hackers, hacktivists, state-sponsored intrusions, industrial
espionage, and insiders. In addition, certain types of attacks could harm us even if our systems are left undisturbed. For example, certain
threats are designed to remain dormant or undetectable, sometimes for extended periods of time, or until launched against a target and
we may not be able to implement adequate preventative measures. Further, there has been an increase in such activities due to the increase
in work-from-home arrangements. The risk of cyberattacks could also be increased by cyberwarfare in connection with the ongoing Russia-Ukraine
and Israel-Hamas conflicts, or other future conflicts, including potential proliferation of malware into systems unrelated to such conflicts.
Any future breach of our operations or those of others in the bitcoin industry, including third-party services on which we rely, could
materially and adversely affect our financial condition and results of operations.

We face risks relating to the custody of our bitcoin, including the loss or destruction of private keys required to access our bitcoin and cyberattacks or other data loss relating to our bitcoin

We will hold our bitcoin with
regulated custodians that have duties to safeguard our private keys. Our custodial services contracts will not restrict our ability to
reallocate our bitcoin among our custodians, and our bitcoin holdings may be concentrated with a single custodian from time to time, including
immediately after this offering. In light of the significant amount of bitcoin we hold, we continually evaluate the need to engage additional
custodians. Additional custodians could achieve a greater degree of diversification in the
