Company believes that bitcoin is attractive because it can serve as a store of value, supported by a robust and public open source architecture,
that is untethered to sovereign monetary policy and can therefore serve as a hedge against inflation. Bitcoin exists entirely in electronic
form, as virtually irreversible public transaction ledger entries on the blockchain, and transactions in bitcoin are recorded and authenticated
not by a central repository, but by a decentralized peer-to-peer network. This decentralization avoids certain threats common to centralized
computer networks, such as denial of service attacks, and reduces the dependency of the bitcoin network on any single system. While the
bitcoin network as a whole is decentralized, the private keys used to access bitcoin balances are not widely distributed and are held
on hardware (which can be physically controlled by the holder or by a third party such as a custodian) or via software programs on third-party
servers and loss of such private keys results in an inability to access, and effective loss of, the corresponding bitcoin. Consequently,
bitcoin holdings are susceptible to all of the risks inherent in holding any electronic data, such as power failure, data corruption,
security breach, communication failure, and user error, among others. These risks, in turn, make bitcoin subject to theft, destruction,
or loss of value from hackers, corruption, or technology-specific factors such as viruses that do not affect conventional fiat currency.
In addition, the bitcoin network relies on open source developers to maintain and improve the bitcoin protocol. Accordingly, bitcoin
may be subject to protocol design changes, governance disputes such as &ldquo;forked&rdquo; protocols, competing protocols, and other
open source-specific risks that do not affect conventional proprietary software.</FONT></P>

Company believes that in the context of the economic and public health crisis precipitated by COVID-19 and the unprecedented government
financial stimulus measures adopted around the world, decreasing interest rates, as well as the breakdown of trust in and between political
institutions and political parties in the United States and globally, bitcoin represents a more attractive store of value than fiat currency,
and further that opportunity for appreciation in the value of bitcoin exists in the event that such factors lead to even more widespread
adoption of bitcoin as a treasury reserve alternative.</FONT></P>

load from the generating station, and thereafter, the infrastructure cost per MW is a matter of distributing power at a container level.
Phase II accounts for 30 MW of the 100 MW project and is anticipated to cost approximately $9 million. The total projected build out
cost for the full 100 MW project is approximately $32 million. These are all in costs covering all equipment and labor needed starting

exists when the carrying amount exceeds its fair value. In testing for impairment, the Company has the option to first perform a qualitative
assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely
than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise, it is required
to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost basis of
the asset. Subsequent reversal of impairment losses is not permitted.</FONT></P>

&ndash; The bitcoin blockchain and the cryptocurrency reward for solving a block is subject to periodic incremental halving. Halving
is a process designed to control the overall supply and reduce the risk of inflation in cryptocurrencies using a Proof-of-Work consensus
algorithm. At a predetermined block, the mining reward is cut in half, hence the term &ldquo;Halving&rdquo;. The last halving for bitcoin
occurred on May 12, 2020. Many factors influence the price of bitcoin and potential increases or decreases in prices in advance of or
following a future halving is unknown.</FONT></P>

March 27, 2018, Jeffrey Feinberg, purportedly joined by the Jeffrey L. Feinberg Personal Trust and the Jeffrey L. Feinberg Family
Trust, filed a complaint against the Company and certain of its former officers and directors. The complaint was filed in the
Supreme Court of the State of New York, County of New York. The plaintiffs purported to state claims under Sections 11, 12(a)(2)
and 15 of the federal Securities Act of 1933 and common law claims for &ldquo;actual fraud and fraudulent concealment,&rdquo;
constructive fraud, and negligent misrepresentation, seeking unspecified money damages (including punitive damages), as well as
costs and attorneys&rsquo; fees, and equitable or injunctive relief. On June 15, 2018, the defendants filed a motion to dismiss
all claims asserted in the complaint and, on July 27, 2018, the plaintiffs filed an opposition to that motion. The court heard
argument on the motion and, on January 15, 2019, the court granted the motion to dismiss, allowing 30 days for the filing of an
amended complaint. On February 15, 2019, Jeffrey Feinberg, individually and as trustee of the Jeffrey L. Feinberg Personal Trust,
and Terrence K. Ankner, as trustee of the Jeffrey L. Feinberg Family Trust, filed an amended complaint that purports to state
the same claims and seeks the same relief sought in the original complaint. On March 7 and 22, 2019, defendants filed motions
to dismiss the amended complaint and on April 5, 2019, plaintiffs filed an opposition to those motions. The court heard oral argument
on the motions to dismiss on July 9, 2019, and at the conclusion of the argument the court took the motions under submission.
On April 22, 2021, the Company was notified the appellate court affirmed the decision to dismiss the case in its entirety</FONT></P>

January 14, 2021, Plaintiff Michael Ho (&ldquo;Plaintiff&rdquo; or &ldquo;Ho&rdquo;) filed a Civil Complaint for Damages and Restitution
(&ldquo;Complaint&rdquo;) against Marathon Digital Holdings, Inc. (the &ldquo;Company&rdquo;) and 10 Doe Defendants. The
Complaint alleges six causes of action against the Company, (1) Breach of Written Contract; (2) Breach of Implied Contract; (3)
Quasi-Contract; (4) Services Rendered; (5) Intentional Interference with Prospective Economic Relations; and (6) Negligent Interference
with Prospective Economic Relations, which is the one plead against &ldquo;all Defendants&rdquo; and is most likely to involve
later named defendants. The claims arise from the same set of facts, Ho alleges that the Company profited from commercially-sensitive
information he shared with the Company and then it refused to compensate him for his role in securing the acquisition of a supplier
of energy for the Company. On February 22, 2021, the Company responded to Mr. Ho&rsquo;s Complaint with a general denial and the
assertion of applicable affirmative defenses. Then, on February 25, 2021, the Company removed the matter to federal court. The
parties are currently engaged in discovery, including written discovery and depositions. Due to outstanding issues of fact and
law, it is impossible to predict the outcome at this time; however, the Company is confident that it will prevail in this litigation
since it did not have a contract with Mr. Ho and he did not disclose any commercially-sensitive information that was used to structure
any joint venture with energy providers.</FONT></P>

were incorporated in the State of Nevada on February 23, 2010 under the name Verve Ventures, Inc. As of the date of this filing,
our name has been changed to Marathon Digital Holdings, Inc. On December 7, 2011, we changed our name to American Strategic Minerals
Corporation and were engaged in exploration and potential development of uranium and vanadium minerals business. In June 2012,
we discontinued our minerals business and began to invest in real estate properties in Southern California. In October 2012, we
discontinued our real estate business when our former CEO joined the firm and we commenced our IP licensing operations, at which
time the Company&rsquo;s name was changed to Marathon Patent Group, Inc. On November 1, 2017, we entered into a merger agreement
with Global Bit Ventures, Inc. (&ldquo;GBV&rdquo;), which is focused on mining digital assets. We have since purchased our cryptocurrency
mining machines and established a data center in Canada to mine digital assets. Following the merger, we intended to add GBV&rsquo;s
existing technical capabilities and digital asset miners and expand our activities in the mining of new digital assets, while
at the same time harvesting the value of our remaining IP assets. On June 28, 2018, the board has determined that it is in the
best interests of the Company and its shareholders to allow the Amended Merger Agreement to expire on its current termination
date of June 28, 2018 without further negotiation or extension. The Board approved to issue 750,000 shares of our common stock
to GBV as a termination fee for canceling the proposed merger between the two companies. The fair value of the common stocks was
$2,850,000.</FONT></P>

intangible asset with an indefinite useful life is not amortized but assessed for impairment annually, or more frequently, when
events or changes in circumstances occur indicating that it is more likely than not that the indefinite-lived asset is impaired.
Impairment exists when the carrying amount exceeds its fair value, which is measured using the quoted price of the digital currency
at the time its fair value is being measured. In testing for impairment, the Company has the option to first perform a qualitative
assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more
likely than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise,
it is required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes
the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted.</FONT></P>

management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules
13a-15(f) and 15d-15(f) under the Exchange Act. Our management is also required to assess and report on the effectiveness of our
internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002 (&ldquo;Section 404&rdquo;).
Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability
of financial reporting and the preparation of financial statements for external purposes of accounting principles generally accepted
in the United States. Management assessed the effectiveness of our internal control over financial reporting as of March 31, 2021.
In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO) in Internal Control - Integrated Framework in the 2013 COSO framework. Based on this assessment, management concluded that
our disclosure controls and procedures were effective.</FONT></P>

material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there

detected on a timely basis. A significant deficiency is a deficiency, or a combination of deficiencies, in internal control over
financial reporting that is less severe than a material weakness, yet important enough to merit attention by those responsible
for oversight of the company&rsquo;s financial reporting.</FONT></P>

March 27, 2018, Jeffrey Feinberg, purportedly joined by the Jeffrey L. Feinberg Personal Trust and the Jeffrey L. Feinberg Family
Trust, filed a complaint against the Company and certain of its former officers and directors. The complaint was filed in the
Supreme Court of the State of New York, County of New York. The plaintiffs purported to state claims under Sections 11, 12(a)(2)
and 15 of the federal Securities Act of 1933 and common law claims for &ldquo;actual fraud and fraudulent concealment,&rdquo;
constructive fraud, and negligent misrepresentation, seeking unspecified money damages (including punitive damages), as well as
costs and attorneys&rsquo; fees, and equitable or injunctive relief. On June 15, 2018, the defendants filed a motion to dismiss
all claims asserted in the complaint and, on July 27, 2018, the plaintiffs filed an opposition to that motion. The court heard
argument on the motion and, on January 15, 2019, the court granted the motion to dismiss, allowing 30 days for the filing of an
amended complaint. On February 15, 2019, Jeffrey Feinberg, individually and as trustee of the Jeffrey L. Feinberg Personal Trust,
and Terrence K. Ankner, as trustee of the Jeffrey L. Feinberg Family Trust, filed an amended complaint that purports to state
the same claims and seeks the same relief sought in the original complaint. On March 7 and 22, 2019, defendants filed motions
to dismiss the amended complaint and on April 5, 2019, plaintiffs filed an opposition to those motions. The court heard oral argument
on the motions to dismiss on July 9, 2019, and at the conclusion of the argument the court took the motions under submission.
On April 22, 2021, the Company was notified the appellate court affirmed the decision to dismiss the case in its entirety.</FONT></P>

January 14, 2021, Plaintiff Michael Ho (&ldquo;Plaintiff&rdquo; or &ldquo;Ho&rdquo;) filed a Civil Complaint for Damages and Restitution
(&ldquo;Complaint&rdquo;) against Marathon Digital Holdings, Inc. (the &ldquo;Company&rdquo;) and 10 Doe Defendants. The
Complaint alleges six causes of action against the Company, (1) Breach of Written Contract; (2) Breach of Implied Contract; (3)
Quasi-Contract; (4) Services Rendered; (5) Intentional Interference with Prospective Economic Relations; and (6) Negligent Interference
with Prospective Economic Relations, which is the one plead against &ldquo;all Defendants&rdquo; and is most likely to involve
later named defendants. The claims arise from the same set of facts, Ho alleges that the Company profited from commercially-sensitive
information he shared with the Company and then it refused to compensate him for his role in securing the acquisition of a supplier
of energy for the Company. On February 22, 2021, the Company responded to Mr. Ho&rsquo;s Complaint with a general denial and the
assertion of applicable affirmative defenses. Then, on February 25, 2021, the Company removed the matter to federal court. The
parties are currently engaged in discovery, including written discovery and depositions. Due to outstanding issues of fact and
law, it is impossible to predict the outcome at this time; however, the Company is confident that it will prevail in this litigation
since it did not have a contract with Mr. Ho and he did not disclose any commercially-sensitive information that was used to structure
any joint venture with energy providers.</FONT></P>
