       Amendment No. 2 to Registration Statement on Form F-4


   1.                                                   Given your disclosure
that maintaining access to a stable power supply is a key challenge
                                                        in the mining business,
and SAI's reliance on secured power in Kazakhstan to support its
                                                        growth, please revise
throughout to reflect recent developments concerning Kazakhstan   s
                                                        political and economic
instability. Discuss the effect of the recent intermittent energy and
                                                        internet access on the
bitcoin hashrate and SAI's operations. State whether this has had or
                                                        is expected to have a
material adverse effect on SAI's operations.
   2.                                                   Please update the
audited financial statements of SAI Tech to include the year ended
                                                        December 31, 2021.
Further disclose how you accounted for treasury shares as referenced
                                                        elsewhere in your

3.       Refer to comment 1 above. With a view toward revised disclosure,
please provide a brief
         analysis as to whether or not the previously disclosed projections
have a reasonable basis
         given these recent developments.

4.       See footnote 3 on page 178. Please disclose how you gave effect to the
warrant agreement
         for 9.8 million shares issued to the Beijing SAI Tech shareholders and
         eventual settlement. Further quantify the Beijing SAI's shareholders'
"return to SAI
         equivalent to the effect of the disposal of an investment in a
subsidiary at carrying value."
         Tell us why only certain of the shareholders who returned their
repatriated investment to
         SAI were issued a warrant agreement.

5.       Refer to the roll-forward schedule of redeemable preferred shares on
page F-78, provided
         in response to prior comment 11. As appropriate, please:
             include the 2,040,816 Series Seed Shares and
             provide separate line items for Series Angel and Series Pre-A
Preferred shares. If
              true, please also clarify that the Series Pre-A shares exclude
the Series Pre-A shares
              underlying the warrant agreement referenced on page F-70.
6.     We note your response to comment 12. It appears the warrant agreement,
       ultimately settled through a warrant denominated in US dollars and
issued by SAI parent
       holding company, was executed in April 2021 by SAI Tech when its
functional currency
       was the RMB (prior to the change of its functional currency to the US
dollar subsequent
       to June 30, 2021). Accordingly, as of its issue date, this warrant
appears to be indexed to
       SAI's own stock pursuant to ASC 815-40-15-7I. A subsequent change in the
       currency does not necessarily result in a change in the accounting
treatment of a liability
