BIT Mining Limited (formerly, 500.com Limited, the “Company”) was incorporated under the laws of the Cayman Islands on April 20, 2007 under the original name of “Fine Success Limited”, which was changed to “500wan.com” on May 9, 2011, and changed to “500.com Limited” on October 9, 2013.

The Company has completed the transformation of its business and become an enterprise that primarily provides cryptocurrency mining, data center operation and mining pool services in 2021.

In June 2022, the Company entered into an agreement with Viking Data Centers that the Company agreed to purchase all remaining equity interest from Viking Data Centers by transferring certain assets that represent 67.5MW, or 45%, of total planned power capacity at the Ohio Mining Site. After completion of the transaction, the Company has exclusive access to 82.5MW of planned electrical power and Viking Data Centers has exclusive access to the remaining 67.5MW, in accordance to their respective equity ownership immediately prior to the transaction.

1. ORGANIZATION (continued)

The Company has previously conducted the lottery business in mainland China through a series of contractual arrangements with Shenzhen Youlanguang Science and Technology Co., Ltd., Shenzhen E-Sun Network Co., Ltd., and Shenzhen Guangtiandi Science and Technology Co., Ltd. (collectively, the “lottery business related variable interest entities (“VIEs”)”), and their respective shareholders. Since March 31, 2021, the Company also consolidated the financial results of Zhejiang Keying Huancai Information Technology Co., Ltd. (“Zhejiang Keying”), a VIE primarily engaged in the provision of data analysis and storage services, through its contractual arrangement with Loto Interactive Information Technology (Shenzhen) Co., Ltd., which is indirectly controlled by the Company after the completion of the acquisition of the majority interest of Loto Interactive Limited on March 31, 2021.

On July 23, 2021, the Company announced the decision to dispose of the VIE structures in mainland China, and on August 3, 2021, the Group has terminated all of the VIE structures with the lottery-related affiliated entities and Zhejiang Keying, and the Group has entered into agreement with Zhejiang Keying and Zhejiang Keying’s shareholders to transfer all of the equity interests of Zhejiang Keying’s subsidiaries to Loto Shenzhen. In February 2022, the Company has completed the transfer of the equity interests of Zhejiang Keying’s subsidiaries to Loto Shenzhen. From July 23, 2021, the Company no longer retained any financial interest over the lottery business related VIEs and accordingly deconsolidated the lottery business related VIEs’ financial statements from the Company’s consolidated financial statements. The disposal of lottery business related VIEs represented a strategic shift and has a major effect on the Company’s result of operations. Accordingly, results of operations related to lottery business related VIEs have been reported as discontinued operations for the six months ended June 30, 2021.

The Company, its subsidiaries are hereinafter collectively referred to as the “Group”.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation and use of estimates

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and the rules and regulations of the United States Securities and Exchange Commission, and should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s most recent consolidated annual financial statements filed with the SEC on Form 20-F.

The accompanying unaudited interim condensed consolidated financial statements do not include all of the information and footnotes required by U.S. GAAP for the consolidated financial statements. Certain information and note disclosures normally included in the Group’s annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted consistent with such rules and regulations. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments necessary for the fair statement of the Group’s financial position as of June 30, 2022 and results of operation and cash flows for the six months ended June 30, 2021 and 2022. Results for the six months ended June 30, 2022 are not necessarily indicative of the results expected for the full fiscal year or for any future period.

The preparation of unaudited interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s unaudited interim condensed consolidated financial statements include, but are not limited to, allowance for credit losses, useful lives of property and equipment and intangible assets, impairment of long-lived assets, long-term investments and goodwill, the valuation of cryptocurrencies, realization of deferred tax assets, uncertain income tax positions, share-based compensation and valuation of contingent consideration from business combination and purchase price allocation for business combination and assets acquisition. Actual results could materially differ from those estimates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Principles of consolidation

The unaudited interim condensed consolidated financial statements of the Group include the financial statements of the Company and its subsidiaries. The results of the subsidiaries are consolidated from the date on which the Company obtains control and continue to be consolidated until the date that such control ceases. A controlling financial interest is typically determined when a company holds a majority of the voting equity interest in an entity. All significant intercompany balances and transactions among the Company and its subsidiaries have been eliminated on consolidation.

Foreign currency translation and change in reporting currency

The functional currency of the Company, BVI, 500wan HK, Bee Computing, Alliance Technologies, Sunstar Technology, Skill Esport, Summit Bend, Ohio I, Ohio II and Asgard is the US$. The functional currency of the Multi Group and its subsidiaries is EUR. The functional currency of Loto Interactive and its subsidiaries is HKD. E-Sun Sky Computer with its former VIEs and Beijing Guixinyanghang determined their functional currencies to be RMB. The Group uses the monthly average exchange rate for the period and the spot exchange rate at the balance sheet date to translate the operating results and financial position, respectively. Translation differences are recorded in accumulated other comprehensive loss as a component of shareholders’ equity.

Transactions denominated in foreign currencies are re-measured into the functional currency at the exchange rates prevailing on the transaction dates. Exchange gains and losses resulting from foreign currency transactions are included in the unaudited interim condensed consolidated statements of comprehensive loss.

Foreign currency translation and change in reporting currency (continued)

Starting from the third quarter of 2021, the Group changed its reporting currency from RMB to US$, to reduce the impact of increased volatility of the US$ to RMB exchange rate on the Group’s reported operating results. The aligning of the reporting currency with the underlying operations will better depict the Group’s results of operations for each period. The related financial statements prior to July 1, 2021 have been recasted to US$ as if the financial statements originally had been presented in US$ since the earliest periods presented. The change in reporting currency resulted in cumulative foreign currency translation adjustment to the Group’s comprehensive loss of a loss of US$40 for the six months ended June 30, 2021.

Business combinations, asset acquisitions and non-controlling interests

The Group accounts for its business combinations using the purchase method of accounting in accordance with ASC 805 (“ASC 805”), “Business Combinations”. The purchase method of accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Group acquired, based on their estimated fair values. The consideration transferred in an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. Contingent consideration is recognized at its fair value on the acquisition date. A liability resulting from contingent consideration is remeasured to fair value as of each reporting date until the contingency is resolved, and subsequent changes in fair value are recognized in earnings. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any non-controlling interests. The excess of (i) the total of cost of acquisition, fair value of the non-controlling interests and acquisition date fair value of any previously held equity interest in the acquiree over, (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

If investment involves the acquisition of an asset or group of assets that does not meet the definition of a business, the transaction is accounted for as an asset acquisition. An asset acquisition is recorded at cost, which includes capitalized transaction costs, and does not result in the recognition of goodwill. The cost of the acquisition is allocated to the assets acquired on the basis of relative fair values.

The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and non-controlling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Group determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cash flows over that period.

In a business combination or asset acquisition, the Company may recognize identifiable intangibles that meet either or both the contractual legal criterion or the separability criterion. Identifiable intangible assets recognized in the Company’s acquisitions generally include brand name, strategic contract and unpatented technology.

For the Company’s majority-owned subsidiaries, non-controlling interests are recognized to reflect the portion of their equity which is not attributable, directly or indirectly, to the Group. “Net loss” on the unaudited interim condensed consolidated statements of comprehensive loss include the “net loss attributable to non-controlling interests”. The cumulative results of operations attributable to non-controlling interests are also recorded as non-controlling interests in the Company’s unaudited interim condensed consolidated balance sheets.

The Group recognized changes in fair value of contingent consideration in the amount of a gain of US$1,247 during the six months ended June 30, 2022, which was related to the remeasurement of the contingent consideration from the acquisition of Alliance International Technologies Limited (formerly, Blockchain Alliance Technologies Limited), which operates the mining pool under the brand of BTC.com. The contingent consideration is settled as of June 30, 2022.

Cryptocurrency assets

Cryptocurrency assets are included in current assets in the accompanying unaudited interim condensed consolidated balance sheets. Cryptocurrency assets generated from the cryptocurrency mining business and the mining pool business are accounted for in connection with the Group’s revenue recognition policy disclosed below.

Cryptocurrencies held are accounted for as intangible assets with indefinite useful lives. An intangible asset with an indefinite useful life is not amortized but assessed for impairment quarterly, 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. For each unit of cryptocurrency, impairment exists when the carrying amount exceeds its fair value, which is measured using the quoted price of the cryptocurrency at the time its fair value is being measured. In testing for impairment, the Group 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 Group 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. For the six months ended June 30, 2021 and 2022, the Group recognized impairment loss of US$8,863 and US$12,620, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Cryptocurrency assets (continued)

Cryptocurrencies generated from the cryptocurrency mining business and the mining pool business as well as the cryptocurrencies distributed to mining pool participants are included within operating activities in the accompanying unaudited interim condensed consolidated statements of cash flows. The sales of cryptocurrencies are included within investing activities in the accompanying unaudited interim condensed consolidated statements of cash flows and any realized gains or losses from such sales are included in gain or loss of disposal of cryptocurrencies in the unaudited interim condensed consolidated statements of comprehensive loss. The Group accounts for its gains or losses in accordance with the first-in-first-out (FIFO) method of accounting.

Nonmonetary transaction

The Group enters into nonmonetary transactions such as distributions of cryptocurrencies to pay for operating expense and acquire non-current asset. Such transactions are accounted for in accordance with ASC 845, “Nonmonetary Transactions”, which requires the transfer or distribution of a nonmonetary asset or liability to be based, generally, on the fair value of the asset or liability that is received or surrendered, whichever is more clearly evident. No gain or loss is recognized on the transaction.

Intangible assets

Intangible assets represent computer software, internet domain name, licensing agreement, and intangible assets arising from business combination and asset acquisitions. Computer software, internet domain name and licensing agreement purchased from third parties are initially recorded at cost and amortized on a straight-line basis over their estimated useful lives of the respective assets. The Group performs valuation of the intangible assets arising from business combination and asset acquisitions to determine the relative fair value to be assigned to each asset acquired. The acquired intangible assets are recognized and measured at fair value and are expensed or amortized using the straight-line approach over the estimated useful life of the assets. Estimated useful lives of the respective assets are set out as follows:


Category		Estimated Useful Life

Computer software		3-10 years
Internet domain name		10 years
Licensing agreement		Agreement term
Intangible assets arising from business combination and asset acquisitions
Licenses and brand name		10 years
Mobile applications and software		5 years
Internet domain name and brand name		10 years
Strategic contract		5 years
Unpatented technology		3 years

Goodwill

The Group assesses goodwill for impairment in accordance with ASC 350-20 (“ASC 350-20”), “Intangibles–Goodwill and Other: Goodwill”, which requires that goodwill to be tested for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC 350-20.

In January 2017, the FASB issued Accounting Standards Update No. 2017-04(“ASU 2017-04”), “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. The Group early adopted the ASU 2017-04 on January 1, 2019.

During the six months ended June 30, 2021 and 2022, no impairment of goodwill was recognized.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Impairment of long-lived assets other than goodwill

The Group evaluates its long-lived assets or asset group, including property and equipment, intangible assets and right-of-use assets, with finite lives for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount of a group of long-lived assets may not be fully recoverable. When these events occur, the Group evaluates the impairment by comparing the carrying amount of the assets to future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the excess of the carrying amount of the asset group over its fair value. For the six months ended June 30, 2022, the Group recorded an impairment loss of US$836 for impairment of mining machines of Loto Interactive in Kazakhstan. No impairment of long-lived assets other than goodwill was recorded during the six months ended June 30, 2021.

Fair value measurements

Financial instruments primarily include cash and cash equivalents, restricted cash, accounts receivables, other receivables, equity investments without readily determinable fair values, equity method investments, accounts payable and accrued expenses and other current liabilities. The Group carries the investment under the measurement alternative basis and equity method investment on other-than-temporary basis. Contingent consideration related to the acquisition of Alliance International Technologies (formerly known as “Blockchain Alliance Technologies Limited”) is included in accrued expenses and other current liabilities in the consolidated balance sheets, the fair value of which was based on the number of shares of ordinary shares that were expected to be issued and the fair value of the ordinary shares of the Company. The carrying values of other financial instruments, approximate their fair values due to their short-term maturities.

The Group’s non-financial assets, including cryptocurrency assets, intangible assets, goodwill and property and equipment are measured at fair value when an impairment charge is recognized. Fair value of cryptocurrencies is based on quoted prices in active markets.

The Group applies ASC 820 (“ASC 820”), “Fair Value Measurements and Disclosures”. ASC 820 defines fair value, establishes a framework for measuring fair value and requires disclosures to be provided on fair value measurement.

ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1— Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2— Include other inputs that are directly or indirectly observable in the marketplace.

Level 3— Unobservable inputs which are supported by little or no market activity.

ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach, and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.

As of June 30, 2022, there is no item of the Group’s assets or liabilities that is measured at fair value on a recurring basis in the period subsequent to its initial recognition.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Related party transactions

A related party is generally defined as (i) any person holds 10% or more of the Company’s securities and their immediate families (ii) the Company’s management, (iii) someone that directly or indirectly controls, is controlled by or is under common control with the Company, or (iv) anyone who can significantly influence the financial and operating decisions of the Company. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. Related parties may be individuals or corporate entities.

Transactions involving related parties cannot be presumed to be carried out on an arm’s-length basis, as the requisite conditions of competitive, free market dealings may not exist. Representations about transactions with related parties, if made, shall not imply that the related party transactions were consummated on terms equivalent to those that prevail in arm’s-length transactions unless such representations can be substantiated. It is not, however, practical to determine the fair value of amounts due from/to related parties due to their related party nature.

Revenue recognition

The Group’s revenues were derived principally from cryptocurrency mining, data center services and mining pool services. The Group also provided sports information service through its former lottery business related VIE subsidiaries and disposed of this business line together with the disposal of VIE structures on July 23, 2021. The Group accounts for revenues under ASC Topic 606 “Revenue from Contracts with Customers” (“ASC 606”).

Revenue is recognized when control of promised goods or services is transferred to the Group’s customers in an amount of consideration to which the Group expects to be entitled to in exchange for those goods or services. The Group follows the five steps approach for revenue recognition under Topic 606: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the Group satisfies a performance obligation.

The primary sources of the Group’s revenues are as follows:

Cryptocurrency mining

The Group has entered into a cryptocurrency mining pool, BTC.com, by executing contracts with the mining pool operator to provide computing power to the mining pool. The contracts are terminable at any time by either party and the Group’s enforceable right to compensation only begins when the Group provides computing power to the mining pool operator. In exchange for providing computing power, the Group is entitled to considerations in the form of cryptocurrencies from the mining pool operator (less pool operator fees to the mining pool operator which are recorded net with revenues), which is calculated based on a predetermined formula agreed by the Group and the mining pool operator as a part of the contracts. The consideration also corresponds to the proportion of computing power the Group contributed to the mining pool operator to the total computing power contributed by all mining pool participants in solving the current algorithm. Providing computing power in cryptocurrency transaction verification services is an output of the Group’s ordinary activities. The provision of computing power is the only performance obligation in the Group’s contracts with the pool operator. The transaction consideration the Group receives is noncash consideration. The Group measures the cryptocurrencies at fair value using the quoted price of the related cryptocurrency at contract inception. All considerations are variable and revenue is recognized when the computing power is provided to the mining pool and there is no uncertainty associated with the variable consideration. There is no significant financing component in these transactions.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Data center services

The Group provides data center services such as providing its customers with rack space, power and equipment, and cloud services such as virtual services, virtual storage, and data backup services, generally based on monthly services provided at a defined price included in the contracts. The performance obligations are the services provided to a customer for the month based on the contract. The transaction price is the price agreed with the customer for the monthly services provided and the revenues are recognized monthly based on the services rendered for the month.

Mining pool services

The Group operates its mining pool, BTC.com, to enable providers of computing power (“pool participants”) to participate in crypto-mining activities in an efficient manner in the blockchain network, in exchange for a fee (“pool operator fee”) for its coordination efforts as the pool operator. The Group receives all the mining rewards, and then allocates mining rewards to each pool participant net of the pool operator fees based on the sharing mechanism predetermined. The mining rewards the mining pool receives from the blockchain network include the block rewards and the transaction verification fees related to the transactions included in the block.

The Group considers itself the principal in transactions with the blockchain networks and recognizes the mining pool revenue on a gross basis. The performance obligation is to create or validate each block. Revenue is recognized at the point when the block creation or validation is complete and the Group has received the rewards. Revenue is measured at the fair value of rewards using the quoted price of the related cryptocurrency at contract inception. The Group considers itself the principal in transactions with the blockchain networks as it coordinates all the computing power within the mining pool, delivers such aggregated computing power to the blockchain network, collects centrally all mining rewards and distributes them in accordance with the predetermined sharing mechanisms. The Group has control over the pool participants’ computing power. Although the pool participants can enter and exit the pool at will and deploy the qualifying types of mining machines at the choices of the pool participants, during the mining process, the Group dictates the tasks and the participants’ mining machines merely follow the allocation prescribed by the Group. As a result, the Group is primarily responsible for fulfilling the promise to provide the specified service. Further, under existing sharing mechanisms, the Group is exposed to the risk that actual block rewards may differ from expected rewards, therefore, bears the inventory risk before the specified service has been transferred to the blockchain network.

Contract balances

The Group does not have any contract assets. The Group’s contract liabilities include advance from customers, which is recorded when consideration is received from a customer prior to providing services to the customer under the terms of a contract. As of December 31, 2021 and June 30, 2022, the Group recorded advance from customers balance of US$744 and US$469 respectively, which was included in “accrued expenses and other current liabilities” in the accompanying unaudited interim condensed consolidated balance sheets. US$672 and US$277 of deferred revenue included in the opening balances of advance from customers was recognized during the six months ended June 30, 2021 and 2022, respectively. The amounts were included in revenues on the accompanying unaudited interim consolidated statements of comprehensive loss.

Refer to Note 21 regarding the discussion of the Group’s disaggregate revenue data.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Cost of services

Cost of mining pool services

Cost of mining pool services which was offered under BTC.com consists primarily of the mining rewards allocated to each pool participant in exchange for their computing power contributed to the mining pool. The mining rewards allocated to the pool participants include both the block rewards as well as the transaction verification fees related to the transactions included in the block, depending on the sharing mechanism chosen by individual pool participants. Cost of mining pool services also consists of other direct costs related to providing the mining pool service such as server fees and labor for maintaining the mining pool service. Cost of mining pool services were US$405,347 from April 15, 2021 to June 30, 2021 and US$447,997 for the six months ended June 30, 2022. These costs are expensed as incurred.

Cost of data center services

The cost of data center services consists primarily of direct production costs related to data center service, including the direct service charges for operations, were US$8,567 from March 31, 2021 to June 30, 2021 and US$4,319 for the six months ended June 30, 2022. These costs are expensed as incurred.

Server leasing and maintenance expenses

Server leasing and maintenance expenses, which consist primarily of leasing expense of hosting servers and other equipment used in providing online services and cryptocurrency mining business, were US$4,140 and US$8,538 for the six months ended June 30, 2021 and 2022, respectively. These costs are expensed as incurred.

Depreciation fees

Depreciation fees, which consist primarily of depreciation of machinery and equipment related to cryptocurrency mining and data center services, were US$5,461 and US$16,584 for the six months ended June 30, 2021 and 2022, respectively. These costs are recorded in unaudited interim condensed consolidated statements of comprehensive loss on a straight-line basis over the useful life of the machinery and equipment.

Amortization fees

Amortization fees, which consist primarily of amortization of intangible assets arising from business combination and assets acquisitions, were US$1,312 and US$4,748 for the six months ended June 30, 2021 and 2022, respectively. These costs are recorded in unaudited interim condensed consolidated statements of comprehensive loss on a straight-line basis over the useful life of the intangible assets.

Cost of services also comprised lottery insurance expenses, regulatory and compliance fees, platform fees, employee costs, account handling expense, business tax and surcharges and other direct costs incurred in providing services. These costs are expensed as incurred.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Sales and marketing expenses

Sales and marketing expenses consist primarily of employee costs, commission to certain internet companies and expenses related to promotional activities. These costs are expensed as incurred.

Service development expenses

Service development expenses consist primarily of personnel-related expenses incurred for the development of, enhancement to, and maintenance of the Group’s website that either (i) did not meet the capitalization criteria in accordance with ASC 350, “Intangibles - Goodwill and other”; or (ii) met the capitalization criteria but the costs cannot be separated on a reasonably cost-effective basis between maintenance and relatively minor upgrades and enhancements. Service development expenses are recognized as expenses when incurred.

Income taxes

The Group follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Group records a valuation allowance to offset deferred tax assets if based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of comprehensive loss in the period that includes the enactment date.

Interest and penalties arising from underpayment of income taxes are computed in accordance with the applicable tax law and is classified in the consolidated statements of comprehensive loss as income tax expense. The amount of interest expense is computed by applying the applicable statutory rate of interest to difference between the tax position recognized and the amount previously taken or expected to be taken in a tax return.

In accordance with the provisions of ASC 740 (“ASC 740”), “Income taxes” the Group recognizes in its financial statements the impact of a tax position if a tax return position or future tax position is “more likely than not” to be sustained upon examination based solely on the technical merits of the position. Tax positions that meet the “more likely than not” recognition threshold are measured at the largest amount of tax benefit, determined on a cumulative probability basis, that has a greater than fifty percent likelihood of being realized upon settlement. The Group’s estimated liability for unrecognized tax position which is included in the “long-term payables” account is periodically assessed for adequacy and may be affected by changing interpretations of laws, rulings by tax authorities, changes and/or developments with respect to tax audits, and expiration of the statute of limitations. The outcome for a particular audit cannot be determined with certainty prior to the conclusion of the audit and, in some cases, appeal or litigation process. The actual benefits or liability ultimately realized may differ from the Group’s estimates. As each audit is concluded, adjustments, if any, are recorded in the Group’s financial statements. Additionally, in future periods, changes in facts, circumstances, and new information may require the Group to adjust the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recognized in the period in which the changes occur.

In conjunction with ASC 740, the Group also applied ASC 740-30 (“ASC 740-30”), “Income Taxes: Other Considerations or Special Areas”, to account for the temporary differences arising from the undistributed earnings of the foreign subsidiaries. According to ASC 740-30, all undistributed earnings of a subsidiary shall be presumed to be transferred to the parent entity. Accordingly, the undistributed earnings of a subsidiary included in consolidated income shall be accounted for as a temporary difference and affect deferred tax expense unless the tax law provides a means by which the investment in a domestic subsidiary can be recovered tax free.

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes”, which simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. The Group adopted the ASU on January 1, 2021. The adoption did not have a material impact on the Group’s consolidated financial statements.

Recent accounting pronouncements

The Group has considered all recent accounting pronouncements and has concluded that there are no recent accounting pronouncements that may have a material impact on its unaudited interim condensed consolidated financial statements, based on current information.

3. CONCENTRATION OF RISKS

Concentration of credit risk

Assets that potentially subject the Group to significant concentration of credit risk primarily consist of cash and cash equivalents, restricted cash, and accounts receivable. As of June 30, 2022, substantially all of the Group’s cash and cash equivalents were deposited in financial institutions located in mainland China, Hong Kong, United States and Malta, which management believes are of high credit quality.

Concentration of suppliers

For the six months ended June 30, 2021 and 2022, the supplier accounted for 10% of more of the Group’s costs was as follows:


	For the six months ended June 30,
	2021		2022
	US$		US$
A	17.8	%	18.7	%

Vulnerability due to change of regulations or policies

The blockchain and cryptocurrency mining business could be significantly affected by, among other things, the regulatory and policy developments in international markets where the Company operates, such as the United States and Kazakhstan. Governmental authorities are likely to continue to issue new laws, rules and regulations governing the blockchain and cryptocurrency industry in and enhance enforcement of existing laws, rules and regulations. For example, the People’s Bank of China (the “PBOC”), Ministry of Industry and Information Technology, State Administration for Industry and Commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission issued “Announcement on Preventing Token Fundraising Risks” on September 4, 2017, prohibiting all organizations and individual from engaging in initial coin offering transactions. On May 21, 2021, the Financial Stability and Development Committee of the State Council in mainland China called for the need to resolutely control financial risks and crack down on cryptocurrency mining and trading activities. On June 18, 2021, the “Notice of the Sichuan Provincial Development and Reform Commission and the Sichuan Provincial Energy Administration on the Cleanup and Shutdown of Virtual Currency Mining Projects” required electricity companies within Sichuan Province to close down power supply to businesses involved in cryptocurrency mining. On June 21, 2021, the Company terminated the operations of the two data centers in Sichuan according to the written notice from the Local Power Supplier.

3. CONCENTRATION OF RISKS (continued)

Vulnerability due to change of regulations or policies (continued)

As of June 30, 2022, the mining pool subsidiary of the Company has completely exited the mainland China market, ceased registering new users from mainland China and retired accounts of existing users from mainland China. The Group has been working on solutions with its existing users in mainland China, such as migrating users’ mining machines to overseas markets so that they have access to the services in a compliant manner.

The Group had begun the development of the international operations before these regulatory and policy developments in mainland China. In the second half of 2021, the Group has finished the migration of the cryptocurrency operations to international markets.

4. ASSET ACQUISITION

On May 31, 2022, the Company completed the first closing of its previously announced share exchange agreement dated April 5, 2021 (as amended and restated in April 2022, the “Amended and Restated Share Exchange Agreement”) entered into by the Company and the shareholders (the “Selling Shareholders”) of the acquisition of Bee Computing (HK) Limited (“Bee Computing”). At the first closing of the Amended and Restated Share Exchange Agreement, the Company issued 16,038,930 of its Class A ordinary shares to the Selling Shareholders.

Mainland China

A new enterprise income tax law (the “EIT Law”) in mainland China was enacted and became effective on January 1, 2008. The EIT Law applies a uniform 25% enterprise income tax (“EIT”) rate to both foreign invested enterprises and domestic enterprises. Accordingly, subsidiaries incorporate in mainland China are subject to the EIT rate of 25% in 2021 and 2022. No provision for the income tax has been made in the financial statements as the subsidiaries incorporated in mainland China had no assessable income for the six months ended June 30, 2021 and 2022.

The Group records a valuation allowance on its deferred tax assets that is sufficient to reduce the deferred tax assets to an amount that is more likely than not to be realized. Future reversal of the valuation allowance will be recognized either when the benefit is realized or when it has been determined that it is more likely than not that the benefit in future earnings will be realized.

As of June 30, 2022, the Group had net operating losses (“NOLs”) of approximately US$62,066 from subsidiaries incorporated in mainland China and US$19,118 from Hong Kong subsidiaries, which can be carried forward to offset future net profit for income tax purposes. The NOLs from subsidiaries incorporated in mainland China as of June 30, 2022 will expire in years 2023 to 2027 if not utilized. The Group recorded a full valuation allowance against the deferred tax assets as we have determined that it was more likely than not that all of our deferred tax assets will not be realized in the future due to our continuing pre-tax and taxable losses.

The Group accounted for uncertainties in income taxes in accordance with ASC 740. The management evaluated the Group’s tax positions and concluded that no provision for uncertainty in income taxes was necessary as of June 30, 2021 and 2022.

17. COMMITMENTS AND CONTINGENCIES

Contractual arrangements among the Company and the former VIEs

Under applicable tax laws and regulations in mainland China, arrangements and transactions among related parties may be subject to audit or scrutiny by the tax authorities in mainland China within ten years after the taxable year when the arrangements or transactions are conducted. The Company could face material and adverse tax consequences if the tax authorities in mainland China were to determine that the Contractual Arrangements among the Company and the respective VIEs were not entered into on an arm’s-length basis and therefore constituted unfavorable transfer pricing arrangements. Unfavorable transfer pricing arrangements could, among other things, result in an upward adjustment on taxation. In addition, the tax authorities in mainland China may impose interest on late payments on the Company and the respective VIEs for the adjusted but unpaid taxes. In the opinion of management, the likelihood of such an upward adjustment on taxation and related interest is remote based on current facts and circumstances.

Guarantees

The Group accounts for guarantees in accordance with ASC topic 460 (“ASC 460”), “Guarantees”. Accordingly, the Group evaluates its guarantees to determine whether (a) the guarantee is specifically excluded from the scope of ASC 460, (b) the guarantee is subject to ASC 460 disclosure requirements only, but not subject to the initial recognition and measurement provisions, or (c) the guarantee is required to be recorded in the financial statements at fair value.

Guarantees (continued)

The memorandum and articles of association of the Company require that the Company indemnify its officers and directors, as well as those who act as directors and officers of other entities at the Company’s request, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to the Company. The indemnification obligations are more fully described in the memorandum and articles of association. The Company purchases standard directors and officers’ insurance to cover claims or a portion of the claims made against its directors and officers. Since a maximum obligation is not explicitly stated in the Company’s memorandum and articles of association and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated.

Historically, the Group has not been required to make payments related to these obligations, and the fair value for these obligations is zero as of December 31, 2021 and June 30, 2022.

Indemnity cost

There was no indemnity cost occurred as of December 31, 2021 and June 30, 2022.

Legal proceedings

From time to time, the Group is subject to legal proceedings and claims in the ordinary course of business. The Group records a liability when it is both probable that a liability will be incurred and the amount of the loss can be reasonably estimated. The Group reviews the need for any such liability on a regular basis and has not recorded any material liabilities in this regard during 2021 and for the six months ended June 30, 2022.

Operating lease commitments

The information of lease commitments is provided in Note 10.

22. DISCONTINUED OPERATIONS

Disposition of VIEs and VIE subsidiaries

On July 23, 2021, the Group terminated all of its lottery business-related VIE contracts for nil consideration and disposed of its Chinese lottery-related business.

From July 23, 2021, the Group no longer retained any financial interest over lottery business related VIEs and accordingly deconsolidated lottery business related VIEs’ financial statements from the Group’s consolidated financial statements. The disposal of lottery business related VIEs represented a strategic shift and has a major effect on the Group’s result of operations. Accordingly, revenues, expenses and cash flows related to lottery business related VIEs have been reclassified in the consolidated financial statements as discontinued operations for the six months ended June 30, 2021.
