associated with acquiring a company that does business in China.
                                                        Your disclosure should
make clear whether these risks could result in a material change in

foreign exchange. Your
         prospectus summary should address, but not necessarily be limited to,
the risks
         highlighted on the prospectus cover page.
2.       We note your disclosure on page 213 that "as a Cayman exempted and
offshore holding
         company, SAI is permitted under PRC laws and regulations to provide
funding to its
         wholly foreign-owned subsidiary in China only through loans or capital
contributions,
         subject to the approval of government authorities and limits on the
amount of capital
         contributions and loans. In addition, SAI   s wholly foreign-owned
subsidiary in China may
         provide Renminbi funding to its consolidated VIE only through
entrusted loans." Please
         expand your disclosure on the prospectus cover page to provide a
description of how cash
         is transferred through the target company's organization and state
whether any transfers,
         dividends, or distributions have been made to date. Similarly, please
expand your
         disclosure in the prospectus summary to provide a clear description of
how cash is
         transferred through the target company's organization. Quantify any
cash flows and
         transfers of other assets by type that have occurred between the
target company and
         its subsidiaries, and the direction of the transfer. Quantify any
dividends or distributions
         that a subsidiary has made to the target company and which entity made
such transfer, and
         their tax consequences. Similarly quantify dividends or distributions
made to U.S.
         investors, the source, and their tax consequences. Your disclosure
should make clear if no
         transfers, dividends, or distributions have been made to date.
Describe any restrictions on
         foreign exchange and the target company's ability to transfer cash
between entities, across
         borders, and to U.S. investors. Describe any restrictions and
limitations on the target
         company's ability to distribute earnings from its businesses to the
parent company and
         U.S. investors.
Questions and Answers
Did the TradeUP Board or a committee thereof obtain a third-party valuation or
fairness opinion
in determining whether or not to proceed..., page 11

3.       Revise to caution shareholders that the Duff & Phelps fairness opinion
opines on the
         fairness of the transaction to TradeUP, as opposed to only those
shareholders unaffiliated
         with the sponsor or its affiliates.
Summary, page 20

4.       In your summary of risk factors, highlight the risks that acquiring a
company with
         substantial operations in China poses to investors. In particular,
describe the significant
         regulatory, liquidity, and enforcement risks with cross-references to
the more detailed
         discussion of these risks in the prospectus. For example, specifically
discuss risks arising
         from the legal system in China, including risks and uncertainties
regarding the
         enforcement of laws and that rules and regulations in China can change
quickly with little
         advance notice; and the risk that the Chinese government may intervene
or influence your
         operations at any time, or may exert more control over offerings
conducted overseas

         and/or foreign investment in companies with substantial operations in
China, which could
         result in a material change in your operations and/or the value of
your common stock.
         Acknowledge any risks that any actions by the Chinese government to
exert more
         oversight and control over foreign investment in companies with
substantial operations in
         China could significantly limit or completely hinder your ability to
offer or continue to
         offer securities to investors and cause the value of such securities
to significantly decline
         or be worthless.
5.       Disclose each permission that SAI is required to obtain from Chinese
authorities to
         operate and issue these securities to foreign investors. State whether
SAI or its
         subsidiaries are covered by permissions requirements from the CSRC,
CAC or any other
         entity, and state affirmatively whether you have received all
requisite permissions and
         whether any permissions have been denied.
6.       Disclose that trading in your securities may be prohibited under the
Holding Foreign
         Companies Accountable Act if the PCAOB determines that it cannot
inspect or fully
         investigate your auditor, and that as a result an exchange may
determine to delist your
         securities. If the PCAOB has been or is currently unable to inspect
your auditor, revise
         your disclosure to so state.
7.       Please disclose whether SAI is required to obtain any approvals to
offer securities to
         foreign investors, whether it received such approvals and the
consequences to you and
         your investors if SAI does not receive or maintain the approvals,
inadvertently conclude
         that such approvals are not required, or applicable laws, regulations,
or interpretations
         change and SAI is required to obtain approval in the future.
Impact of the Business Combination on New SAI's Public Float, page 30

8.       Please revise to disclose all possible sources and extent of dilution
that shareholders who
         elect not to redeem their shares may experience in connection with the
Business
         Combination. Provide disclosure of the impact of each significant
source of dilution,
         including the amount of equity held by founders and warrants retained
by redeeming
         shareholders, at each redemption level, including any needed
assumptions.

Risk Factors, page 45

11.      Given the Chinese government   s significant oversight and discretion
over the conduct of
         the target company's business, please revise to separately highlight
the risk that the
         Chinese government may intervene or influence your target company's
operations at any
         time, which could result in a material change in your operations
and/or the value of your
         common stock. Also, given recent statements by the Chinese government
indicating an
         intent to exert more oversight and control over offerings that are
conducted overseas
         and/or foreign investment in China-based issuers, acknowledge the risk
that any such
         action could significantly limit or completely hinder your ability to
offer or continue to
         offer securities to investors and cause the value of such securities
to significantly decline
         or be worthless.
12.      In light of recent events indicating greater oversight by the
Cyberspace Administration of
         China over data security, particularly for companies seeking to list
on a foreign exchange,
         please revise your disclosure to explain how this oversight impacts
your target company's
         business and your offering and to what extent you believe that you are
compliant with the
         regulations or policies that have been issued by the CAC to date.
13.      We note from the audit opinion that you have a U.S. based auditor that
is registered with
         the PCAOB and currently subject to PCAOB inspection. Please disclose
any material
         risks to the company and investors if it is later determined that the
PCAOB is unable to
         inspect or investigate completely your target company's auditor
because of a position
         taken by an authority in a foreign jurisdiction. For example, disclose
the risk that lack of
         inspection could cause trading in your securities to be prohibited
under the Holding
         Foreign Companies Accountable Act and as a result an exchange may
determine to delist
         your securities.
14.      Please expand your risk factor disclosure to discuss that the United
States Senate passed
         the Accelerating Holding Foreign Companies Accountable Act, which, if
enacted, would
         decrease the number of non-inspection years from three years to two,
thus reducing the
         time period before your securities may be prohibited from trading or
delisted.

Our business is dependent on a small number..., page 48

15.      You disclose on page 48 that SAI depends on a small number of digital
asset mining
         equipment suppliers such as Bitmain Technologies, Ltd. Please disclose
the material terms
         of SAI's agreement with this supplier as well as any other suppliers
SAI is dependent
         upon. Also, file any contracts with the supplier as exhibits or tell
us why this is not
         required.

Risks Related to TradeUP and the Business Combination, page 82

16.      Please highlight the risk that the Sponsor will benefit from the
completion of a Business
         Combination and may be incentivized to complete an acquisition of a
less favorable target
         company or on terms less favorable to shareholders rather than
liquidate.
17.      Disclose the material risks to unaffiliated investors presented by
taking the target
         company public through a merger rather than an underwritten offering.
These risks could
         include the absence of due diligence conducted by an underwriter that
would be subject to
         liability for any material misstatements or omissions in a
registration statement.
Proposal 1 - The Business Combination Proposal
Certain Unaudited Projected Financial Information of SAI, page 131

18.      We note you have provided more than three years of financial
projections. Given your
         limited operating history, please explain how it is reasonable to
project this information
         out through 2026.
19.      We note that the projections are based on numerous variables and
assumptions, including
         economic, market and operational assumptions, and that certain
assumptions are derived
         from what SAI's management "then believed to be potentially
achievable." Describe what
         is meant by "potentially achievable" and whether SAI's management
opined on the
         likelihood of certain of these assumptions coming to fruition.
Additionally, disclose any
         specific assumptions about growth rates that were used to prepare the
projections.
20.      Provide us with the legal basis for the disclaimer on page 132 of "any
obligation to update
         or otherwise revise or reconcile the projections to reflect
circumstances existing after the
         date the projections were generated or to reflect the occurrence of
future events even in
         the event that any or all of the assumptions underlying the
projections are shown to be in
         error." Refer generally to Item 10(b)(3)(iii) of Regulation S-K.
U.S. Federal Income Tax Considerations, page 144

21.      We note your disclosure that there should be no material U.S. federal
income tax
         consequences to U.S. Holders of New SAI Class A ordinary shares and
warrants as a
         result of the Business Combination. Please file a tax opinion as an
exhibit to the filing in
         support of this conclusion. If you cannot give a    will    opinion,
please discuss the facts or
         circumstances resulting in this uncertainty, the degree of
uncertainty, and add appropriate
         risk factor disclosure addressing the risk to investors regarding
uncertain tax treatment.
