 the correct naming convention for forked crypto assets.
Due to the lack of a central registry or rulemaking body, no single entity has the ability to dictate the nomenclature of forked crypto
assets, causing

disagreements and a lack of uniformity among
platforms on the nomenclature of forked crypto assets, and which results in further confusion to customers as to the nature of assets
they hold on platforms, and which can negatively impact the value of the crypto assets. In addition, several of these forks were contentious
and as a result, participants in certain communities may harbor ill will towards other communities. As a result, certain community members
may take actions that adversely impact the use, adoption, and price of bitcoin, or any of their forked alternatives.

Furthermore, hard forks can
lead to new security concerns. For instance, when the Ethereum and Ethereum Classic networks split in July 2016, replay attacks,
in which transactions from one network were rebroadcast on the other network to achieve “double-spending,” plagued platforms
that traded Ethereum through at least October 2016, resulting in significant losses to some crypto asset platforms. Similar replay
attacks occurred in connection with the bitcoin cash and bitcoin cash SV network split in November 2018. Another possible result
of a hard fork is an inherent decrease in the level of security due to the splitting of some mining power across networks, making it easier
for a malicious actor to exceed 50% of the mining power of that network, thereby making crypto assets that rely on proof-of-work more
susceptible to attack, as has occurred with Ethereum Classic.

We intend to recognize forked
and airdropped assets consistent with our custodians. We may not immediately or ever have the ability to withdraw a forked or airdropped
bitcoin by virtue of bitcoins that we hold with our custodians. Future forks may occur at any time. A fork can lead to a disruption of
networks and our information technology systems, cybersecurity attacks, replay attacks, or security weaknesses, any of which can further
lead to temporary or even permanent loss of our and our assets.

The due diligence procedures conducted by us and our liquidity providers to mitigate transaction risk may fail to prevent transactions with a sanctioned entity.

We will execute trades through
U.S.-based liquidity providers, and rely on these third parties to implement controls and procedures to mitigate the risk of transacting
with sanctioned entities. While we expect our
