    5. We reviewed your response to comment 16 and the revisions to your
disclosure. We note
       that sales of common stock disclosed in the consolidated statements of
shareholders'
       equity (deficit) exceeds the proceeds from the issuance of common stock
in the
       consolidated statements of cash flows. Please tell us what the
difference represents. If
       the difference is attributable to non-cash financing transactions,
please disclose the non-
       cash transactions in accordance with ASC 230-10-50-3.

    6. We reviewed your response to comment 20 and the revisions to your
disclosure. Please
       tell us how you concluded that your investments in digital currencies
are fully impaired
       and whether you tested the indefinite-lived assets for impairment in
accordance with ASC
       350-30-35. In addition, please explain to us how you determined the fair
value of digital
       currencies in determining the amount of the impairment loss. We may have
further
       substantive comment.

Investments of SAFTs and Pre-ICO Tokens, page 69

    7. Please explain to us why you combine disclosures regarding the
investments in equity
       securities and the promissory note receivable with your disclosures
regarding SAFTs
       rather than providing separate note disclosures.

    8. We reviewed your response to comment 14 and the revisions to your
disclosure. You
       disclose that investments in Utility Tokens received as part of your
SAFT agreements are

        accounted for as financial assets measured and recorded at cost and
that you wrote-off
        your investments in Utility Tokens since there is no current or future
value related to the
        Utility Tokens. As previously requested, please tell us your basis in
GAAP for
        accounting for the Utility Tokens as financial assets as opposed to
intangible assets. In
        addition, please tell us your basis for concluding that there is no
current or future value
        related to the Utility Tokens. Finally, please tell us whether the
Utility Tokens were
        reviewed for impairment in accordance with the guidance in ASC 360-10
and explain to
        us in detail how you measured the amount of the impairment loss
recognized. We may
        have further substantive comment.

Note 3. Restatement of Financial Statements, page 77

    9. Please disclose the effect of the corrections on each financial
statement line item,
       including net loss per share and cash flows. Please refer to ASC
250-10-50-7a. Please
       note that this comment also applies to Amendment No. 3 to Form 10-Q for
the quarter
       ended January 31, 2018.

Note 4. Investment in LegatumX, page 78

    10. We reviewed your response to comment 21 and the revisions to your
disclosure regarding
        the consolidation of LegatumX, a variable interest entity. Please tell
us in detail why
        Legatum is considered to be a variable interest entity. In addition,
please revise to
        provide the disclosures required by ASC 810-10-50.

    11. We note that you may receive additional shares of LegatumX common stock
if
        LexatumX is able to sell the shares of common stock you issued to
LexatumX following
        the effective date of your Form 10. Please revise your disclosure to
discuss the impact of
        the withdrawal of Form 10 on the terms of the agreement with LexatumX.
In addition,
        please tell us in detail how you have the power to direct the
activities of Legatum that
        most significantly impact Legatum's economic performance and the
obligation to absorb
        losses of Legatum or the right to receive benefits from Legatum that
could potentially be
        significant to Legatum.
