 or other blockchain protocol network, as applicable, running simultaneously, but with each split network’s crypto asset lacking interchangeability. A “hard fork” — where there is disagreement among the users about the rules of the network — can have a significant negative impact on value of the crypto asset. The bitcoin has been subject to “forks” that resulted in the creation of new networks, including bitcoin cash ABC, bitcoin cash SV, bitcoin diamond, bitcoin gold and others. Some of these forks have caused fragmentation among platforms as to 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-workmore 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
