Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 3. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, AIkido Labs LLC. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The accompanying consolidated financial statements have been prepared in conformity with US GAAP. This requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the period. The Company’s significant estimates and assumptions include stock-based compensation, the valuation of investments, the valuation of notes receivable and the valuation allowance related to the Company’s deferred tax assets. Certain of the Company’s estimates could be affected by external conditions, including those unique to the Company and general economic conditions. It is reasonably possible that these external factors could have an effect on the Company’s estimates and could cause actual results to differ from those estimates and assumptions. Segments The Company operates in one operating segment and, accordingly, no segment disclosures have been presented herein. Concentration of Cash The Company maintains cash balances at two financial institutions in checking accounts and money market accounts. The Company considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. The Company has not experienced any losses in such accounts. There were no cash equivalents as of December 31, 2021 and 2020. Marketable Securities Marketable securities are classified as trading and are carried at fair value. The Company’s marketable securities consist of highly liquid mutual funds and exchange-traded & closed-end funds which are valued at quoted market prices. Research and Development Research and development costs, including acquired in-process research and development expenses for which there is no alternative future use, are expensed as incurred. Advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. Accounting for Warrants The Company accounts for the issuance of common stock purchase warrants issued in connection with the equity offerings in accordance with the provisions of ASC 815, Derivatives and Hedging (“ASC 815”). The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) gives the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). Stock-based Compensation The Company accounts for share-based payment awards exchanged for services at the estimated grant date fair value of the award. Stock options issued under the Company’s long-term incentive plans are granted with an exercise price equal to no less than the market price of the Company’s stock at the date of grant and expire up to ten years from the date of grant. These options generally vest over a one- to five-year period. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model and the assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. Expected Term - The expected term of options represents the period that the Company’s stock-based awards are expected to be outstanding based on the simplified method, which is the half-life from vesting to the end of its contractual term. Expected Volatility - The Company computes stock price volatility over expected terms based on its historical common stock trading prices. Risk-Free Interest Rate - The Company bases the risk-free interest rate on the implied yield available on U. S. Treasury zero-coupon issues with an equivalent remaining term. Expected Dividend - The Company has never declared or paid any cash dividends on its common shares and does not plan to pay cash dividends in the foreseeable future, and, therefore, uses an expected dividend yield of zero in its valuation models. The Company accounts for forfeitures as they occur. Fair Value Option – Short-term Note and Convertible Note The guidance in ASC 825, Financial Instruments, provides a fair value option election that allows entities to make an irrevocable election of fair value as the initial and subsequent measurement attribute for certain eligible financial assets and liabilities. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. The decision to elect the fair value option is determined on an instrument-by-instrument basis and must be applied to an entire instrument and is irrevocable once elected. Assets and liabilities measured at fair value pursuant to this guidance are required to be reported separately in our consolidated balance sheets from those instruments using another accounting method. Long-term investments Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2016-01 and related ASU 2018-03 concerning recognition and measurement of financial assets and financial liabilities. In adopting this guidance, the Company has made an accounting policy election to adopt an adjusted cost method measurement alternative for investments in equity securities without readily determinable fair values. For equity investments that are accounted for using the measurement alternative, the Company initially records equity investments at cost but is required to adjust the carrying value of such equity investments through earnings when there is an observable transaction involving the same or a similar investment with the same issuer or upon an impairment. Deposits In April 2021, the Company deposited $5 million with a fund to identify opportunities to expand the Company’s core business strategies in Asia. The cash are held in bank accounts on behalf of the Company until the fund manager identifies investments. During the year ended December 31, 2021, the Company incurred advisory fees and legal fee of approximately $0.8 million, and the balance held in cash in this fund was $4.2 million as of December 31, 2021. Income Taxes The Company uses the asset and liability method of accounting for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”). Under this method, income tax expense is recognized as the amount of: (i) taxes payable or refundable for the current year and (ii) deferred tax consequences of temporary difference resulting from matters that have been recognized in the Company’s financial statement or tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities measured at the enacted tax rates in effect for the year in which these items are expected to reverse. Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. Recently Adopted Accounting Standards In August 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-13, “Fair Value Measurement (Topic 820), - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the update. The Company adopted this ASU on January 1, 2020 and the adoption of this ASU did not have a material impact on its consolidated financial statements or related disclosures. In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU No. 2019-12 effective January 1, 2021, and the adoption did not have a material impact on its consolidated financial statements.
