Nature of Business and Organization [Abstract]
Nature of business and organization	Note 1 – Nature of business and organization Golden Bull Limited (“Golden Bull Cayman” or the “Company”) is a holding company incorporated on February 17, 2017, under the laws of the Cayman Islands. The Company has no substantial operations other than holding all of the outstanding share capital of Point Cattle Holdings Limited (“Golden Bull BVI”). Golden Bull BVI is also a holding company holding all of the outstanding share capital of Point Cattle Group Company Limited (“Golden Bull HK”). Golden Bull HK is also a holding company holding all of the outstanding equity of Shanghai Fuyu Information and Technology Co., Ltd. (“Golden Bull WFOE”). The Company, through its variable interest entity (“VIE”), Shanghai Dianniu Internet Finance Information Service Co. Ltd. (“Shanghai Dianniu”), is engaged in providing services for online marketplace connecting borrowers and lenders, and, through its VIE, Shanghai Baoxun Advertisement Design Co. Ltd. (“Shanghai Baoxun”), intends to engage in design and production of online advertisement and marketing survey services for online marketplace. The Company’s headquarter is located in the city of Shanghai, in the People’s Republic of China (the “PRC” or “China”). All of the Company’s business activities are carried out by Shanghai Dianniu. Shanghai Baoxun currently does not have any operations as of the date hereof. In 2018, Shanghai Youwang Vehicle Rental Limited (“Shanghai Youwang”) and Shanghai Xingjiuhao Network Technology Limited (“Shanghai Xingjiuhao” or the “Xingjiuhao”) were established as subsidiaries of Shanghai Dianniu. Shanghai Youwang intends to engage in vehicle sales, vehicle rental, providing consultation and services in the field of automotive technology. Xingjiuhao is going to engage in production and sales for Internet of Things (“IoT”) technology and technical consulting. Both Shanghai Youwang and Xingjiuhao do not have any operations as of the date hereof since their incorporations. On June 8, 2017, Golden Bull Cayman completed its reorganization of entities under the common control of three shareholders, who collectively owned a majority of the equity interests of Golden Bull Cayman prior to the reorganization. Golden Bull Cayman, Golden Bull BVI, and Golden Bull HK, were established as the holding companies of Golden Bull WFOE. Golden Bull WFOE is the primary beneficiary of Shanghai Dianniu and Shanghai Baoxun, and all of these entities included in Golden Bull Cayman are under common control, which results in the consolidation of Shanghai Dianniu and Shanghai Baoxun which have been accounted for as a reorganization of entities under common control at carrying value.

Summary of Significant Accounting Policies [Abstract]
Summary of significant accounting policies	Note 2 – Summary of significant accounting policies Liquidity In 2018, due to the downturn situation in the overall industry, and the Company invested a large amount of money to promote the business, which led to a net loss of approximately $3.54 million and a negative cash flows from operating activities of approximately $5.05 million for the Company during the fiscal year. Net loss for the year ended December 31, 2017 was $996,825 and a negative cash flows from operating activities was approximately $1.91 million. However, after the third quarter of 2018, the industry situation has begun to improve, the company’s revenue level has gradually picked up, and the scale of losses has gradually narrowed. In the first quarter of fiscal year 2019, the Company’s revenue has exceeded the highest level in history and achieved profitability. Therefore, as long as the Company continues to focus on P2P industry, to increase the number of customers and expand the new line of business to car rental, the Company will achieve profitability. The CEO of the Company, major shareholder of the Company, confirms that he will personally provide all the necessary financial support to the Company to ensure its sufficient working capital for the future business operations. We believe that our current working capital is sufficient to support our operations for the next twelve months from the report issuance date. Basis of presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities Exchange Commission (“SEC”). Principles of consolidation The consolidated financial statements include the accounts of the Company, its subsidiaries, and their VIEs. All intercompany transactions and balances are eliminated upon consolidation. Use of estimates and assumptions The preparation of 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 and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the periods presented. Significant estimates required to be made by management include, but are not limited to, useful lives of property, plant and equipment, deferred income tax and share based compensation. Actual results could differ from these estimates. Foreign currency translation and transaction The reporting currency of the Company is the U.S. dollar. The Company in China conducts its businesses in the local currency, Renminbi (RMB), as its functional currency. Assets and liabilities are translated at the unified exchange rate as quoted by the People’s Bank of China at the end of the period. The statement of income accounts are translated at the average translation rates and the equity accounts are translated at historical rates. Translation adjustments resulting from this process are included in accumulated other comprehensive income (loss). Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the results of operations as incurred. Translation adjustments were included in accumulated other comprehensive income (loss). The balance sheet amounts, with the exception of shareholders’ equity at December 31, 2018 and 2017 were translated at 6.8776 RMB and 6.5067 RMB to $1.00, respectively. The shareholder’s equity accounts were stated at their historical rate. The average translation rates applied to the consolidated statements of operatons for the years ended December 31, 2018, 2017 and 2016 were 6.6163 RMB, 6.7563 RMB and 6.6404 RMB to $1.00, respectively. Cash flows were also translated at average translation rates for the periods, therefore, amounts reported on the statement of cash flows will not necessarily agree with changes in the corresponding balances on the consolidated balance sheets. Fair value measurement The accounting standard regarding fair value of financial instruments and related fair value measurements defines financial instruments and requires disclosure of the fair value of financial instruments held by the Company. The accounting standards define fair value, establish a three-level valuation hierarchy for disclosures of fair value measurement and enhance disclosure requirements for fair value measures. The three levels are defined as follow: ● Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. ● Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the assets or liability, either directly or indirectly, for substantially the full term of the financial instruments. ● Level 3 inputs to the valuation methodology are unobservable and significant to the fair value. The carrying amounts included in current assets and current liabilities are reported in the consolidated balance sheets as approximate fair value because of the short period of time between the origination of such instruments and their expected realization and their current market rates of interest. The long-term prepaid expense is approximate to its carrying value. Revenue recognition On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09 Revenue from Contracts with Customers (ASC 606) using the modified retrospective method for contracts that were not completed as of January 1, 2018. This did not result in an adjustment to retained earnings upon adoption of this new guidance as the Company’s revenue was recognized based on the amount of consideration we expect to receive in exchange for satisfying the performance obligations. The core principle underlying the revenue recognition ASU is that the Company will recognize revenue to represent the transfer of goods and services to customers in an amount that reflects the consideration to which the Company expects to be entitled in such exchange. This will require the Company to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time, based on when control of goods and services transfers to a customer. The Company’s revenue streams are primarily recognized at a point in time. The ASU requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that the Company (i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, including variable consideration to the extent that it is probable that a significant future reversal will not occur, (iv) allocate the transaction price to the respective performance obligations in the contract, and (v) recognize revenue when (or as) the Company satisfies the performance obligation. The application of the five-step model to the revenue streams compared to the prior guidance did not result in significant changes in the way the Company records its revenue. Upon adoption, the Company evaluated its revenue recognition policy for all revenue streams within the scope of the ASU under previous standards and using the five-step model under the new guidance and confirmed that there were no differences in the pattern of revenue recognition. Transaction Fees Management Fees In applying judgment, the Company considered customers’ expectations of performance, materiality and the core principles of ASC Topic 606. The aforementioned revenues are recognized and the Company’s performance obligations (control of services) are generally transferred to the customers at the time of loan issuance. The Company’s contracts with borrowers generally do not include any variable consideration. Sales taxes Incentives In order to incentivize lenders, the Company provides incentives to marketplace lenders, who commit a certain amount of money for a period of time. During the relevant incentive program period, the Company set certain thresholds for the lenders to qualify for the cash incentive. When a qualified investment is made by a lender, the incentive payment is paid to the lender as a percentage of investment amount at the time of loan issuance as part of its investment to the specified loan that he/she has invested. The incentive expenses are recognized in our selling expenses in the accompanying consolidated statements of operations and comprehensive loss. These expenses amounted to $2,191,498, $1,497,279 and $503,238 for the years ended December 31, 2018, 2017 and 2016, respectively. Servicing Expense Servicing expenses are paid by the Company to a third party platform provider on each deposit made by the lenders into their respective fund accounts held by the third party platform fund accounts. The amount of these expenses is based upon the deposit amount. The servicing expenses are recognized in our selling expenses in the accompanying consolidated statements of operations and comprehensive loss. These expenses amounted to $134,374, $205,604 and $105,386 for the years ended December 31, 2018, 2017 and 2016, respectively. Verification, credit assessment and the decision-making processes costs Costs related to verification and credit assessment are recognized in the selling expenses in our accompanying consolidated statements of operations. Costs related to the decision-making processes are recognized in the general and administration expenses in our accompanying consolidated statements of operations. These expenses are immaterial to our consolidated statements of operations for the years ended December 31, 2018, 2017 and 2016. Cash, cash equivalents and restricted cash Cash, cash equivalents and restricted cash consist of cash on hand, demand deposits, short-term investment placed with banks or other financial institutions and have original maturities of less than six months and restricted cash, deposit of $600,000 was to fund an escrow account established for purpose of indemnifying the underwriter of the initial public offering in March 2018 as restricted cash for 30 months, which was classified as non-current assets as of December 31, 2018. Cash and cash equivalents also consist of funds earned from the Company’s operating revenues which were held at a third party platform fund accounts which are unrestricted as to immediate withdrawal and use. Property and equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method after consideration of the estimated useful lives and estimated residual value. The estimated useful lives are as follows: Useful Life Estimated Residual Value Office equipment and furnishing 3-5 years 5 % Leasehold improvements Shorter of the remaining lease terms or estimated useful lives - The cost and related accumulated depreciation and amortization of assets sold or otherwise retired are eliminated from the accounts and any gain or loss is included in the consolidated statements of operations and comprehensive loss. Expenditures for maintenance and repairs are charged to earnings as incurred, while additions, renewals and betterments, which are expected to extend the useful life of assets, are capitalized. The Company also re-evaluates the periods of depreciation and amortization to determine whether subsequent events and circumstances warrant revised estimates of useful lives. Impairment for long-lived assets Long-lived assets, including property and equipment with finite lives are reviewed 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 value of an asset may not be recoverable. The Company assesses the recoverability of the assets based on the undiscounted future cash flows the assets are expected to generate and recognize an impairment loss when estimated discounted future cash flows expected to result from the use of the asset plus net proceeds expected from disposition of the asset, if any, are less than the carrying value of the asset. If an impairment is identified, the Company would reduce the carrying amount of the asset to its estimated fair value based on a discounted cash flows approach or, when available and appropriate, to comparable market values. As of December 31, 2018 and 2017, no impairment of long-lived assets was recognized. Deferred rent The Company leases office space and apartment units under operating lease agreements. Certain lease agreements contain scheduled rent increases, tenant improvement allowances or free rent clauses during the term of the lease which are recorded as deferred rent liabilities. Deferred rent liabilities represent the cumulative amount charged to operations under these leases in excess of the amounts paid and was included in prepaid expenses. Rent expense is amortized on a straight-line basis to operating expense over the applicable lease term. Research and development Research and development costs, which include the salary of the Company’s research and development department and benefit and website development cost, are expensed as incurred. Advertising costs Advertising costs are expensed as incurred and included in selling expenses. These expenses amounted to $431,734 ,$460,351 and $373,510 for the years ended December 31, 2018, 2017 and 2016, respectively. Income taxes The Company accounts for income taxes in accordance with U.S. GAAP for income taxes. Under the asset and liability method as required by this accounting standard, the recognition of deferred income tax liabilities and assets for the expected future tax consequences of temporary differences between the income tax basis and financial reporting basis of assets and liabilities. Provision for income taxes consists of taxes currently due plus deferred taxes. The charge for taxation is based on the results for the fiscal year as adjusted for items, which are non-assessable or disallowed. It is calculated using tax rates that have been enacted or substantively enacted by the balance sheet date. Deferred taxes are accounted for using the asset and liability method in respect of temporary differences arising from differences between the carrying amount of assets and liabilities in the consolidated financial statements and the corresponding tax basis used in the computation of assessable tax profit. Deferred tax liabilities are recognized for all future taxable temporary differences. Deferred tax assets are recognized to the extent that it is probable that taxable income will be available against which deductible temporary differences can be utilized. Deferred tax is calculated using tax rates that are expected to apply to the period when the asset is realized or the liability is settled. Deferred tax is charged or credited in the operations of statement, except when it is related to items credited or charged directly to equity. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. An uncertain tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Penalties and interest incurred related to underpayment of income tax are classified as income tax expense in the period incurred. PRC tax returns filed in the year ended December 31, 2018 and 2017 are subject to examination by any applicable tax authorities. Non-controlling Interest Non-controlling interest mainly consists of an aggregate of 6.8% (amended from 10.8% on December 4, 2017 as a result of a former Shareholder of Shanghai Dianniu transferred its 4.0625% equity interest to a Shanghai Dianniu Participating Shareholder) of the equity interests of Shanghai Dianniu held by two entities. The non-controlling interests are presented in the consolidated balance sheets, separately from equity attributable to the shareholders of the Company. Non-controlling interests in the results of the Company are presented on the face of the consolidated statements of operations as an allocation of the total income or loss for the year between non-controlling interest holders and the shareholders of the Company. Earnings (loss) per share Basic earnings (loss) per share are computed by dividing income (loss) available to ordinary shareholders of the Company by the weighted average common shares outstanding during the period. Diluted earnings (loss) per share takes into account the potential dilution that could occur if securities or other contracts to issue common shares were exercised and converted into common shares. As of December 31, 2018 and 2017, there were no dilutive shares. Employee benefits The full-time employees of the Company are entitled to staff welfare benefits including medical care, housing fund, pension benefits, unemployment insurance and other welfare, which are government mandated defined contribution plans. The Company is required to accrue for these benefits based on certain percentages of the employees’ respective salaries, subject to certain ceilings, in accordance with the relevant PRC regulations, and make cash contributions to the state-sponsored plans out of the amounts accrued. Total expenses for the plans were $325,086, $260,451 and $159,352 for the years ended December 31, 2018, 2017 and 2016. Non-employees stock based conpensation Share-based payment transactions with non-employees shall be measured at the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. Recently issued accounting pronouncements In February 2016, the FASB issued ASU 2016-02,“Leases” to provide a new comprehensive model for lease accounting. Under this guidance, lessees and lessors should apply a “right-of-use” model in accounting for all leases (including subleases) and eliminate the concept of operating leases and off-balance sheet leases. This guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact on its consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In June, 2018, the FASB issued ASU No. 2018-07 to provide guidance to reduce cost and complexity and to improve financial reporting for share-based payments issued to non-employees (for example, service providers, external legal counsel, suppliers, etc.). The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements. The Company does not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the Company’s consolidated balance sheets, statements of operations and comprehensive loss and statements of cash flows.

Variable Interest Entity [Abstract]
Variable interest entity	Note 3 – Variable interest entity On June 8, 2017, Golden Bull WFOE entered into Contractual Arrangements with Shanghai Dianniu and Shanghai Baoxun and its Participating Shareholders. On December 4, 2017, Shanxi Xifeng Investment Co., Ltd., a former Shareholder of Shanghai Dianniu, transferred its 4.0625% equity interest in Shanghai Dianniu to Xiaohui Liu, a Participating Shareholder. As a result, Golden Bull WFOE, Shanghai Dianniu, and Shanghai Dianniu Participating Shareholders amended the Contractual Arrangements and the equity interest of Shanghai Dianniu Participating Shareholders increased from 89.2% to 93.2% in the Contractual Arrangements. The significant terms of these Contractual Arrangements are summarized in “Note 1 - Nature of business and organization” above. As a result, the Company classifies Shanghai Dianniu and Shanghai Baoxun as VIE’s. A VIE is an entity that has either a total equity investment that is insufficient to permit the entity to finance its activities without additional subordinated financial support, or whose equity investors lack the characteristics of a controlling financial interest, such as through voting rights, right to receive the expected residual returns of the entity or obligation to absorb the expected losses of the entity. The variable interest holder, if any, that has a controlling financial interest in a VIE is deemed to be the primary beneficiary and must consolidate the VIE. Golden Bull WFOE is deemed to have a controlling financial interest and be the primary beneficiary of Shanghai Dianniu because it has both of the following characteristics: (1) The power to direct activities at Shanghai Dianniu and Shanghai Baoxun that most significantly impact such entity’s economic performance, and (2) The obligation to absorb losses of, and the right to receive benefits from Shanghai Dianniu and Shanghai Baoxun that could potentially be significant to such entity. Accordingly, the accounts of Shanghai Dianniu and Shanghai Baoxun are consolidated in the accompanying financial statements pursuant to ASC 810-10, Consolidation. In addition, their financial positions and results of operations are included in the Company’s consolidated financial statements. The carrying amounts of the VIEs’ consolidated assets and liabilities are as follows: December 31, 2018 December 31, 2017 Current assets $ 3,721,696 $ 7,304,993 Property and equipment, net 723,777 83,522 Other non-current assets 4,322,847 1,984,507 Total assets 8,768,320 9,373,022 Total liabilities 1,902,732 469,232 Net assets $ 6,865,588 $ 8,903,790 December 31, 2018 December 31, 2017 Current liabilities: Other payables and accrued liabilities $ 1,854,947 $ 433,585 Taxes payable 47,785 35,647 Total liabilities $ 1,902,732 $ 469,232 The summarized operating results of the VIEs’ are as follows: For the year ended December 31, 2018 For the year ended December 31, 2017 For the year ended December 31, 2016 Operating revenues $ 7,889,201 $ 6,953,757 $ 3,705,770 Income (loss) from operations $ (2,298,290 ) $ (871,143 ) $ 216,854 Net income (loss) $ (1,641,580 ) $ (508,491 ) $ 164,811

In addition, the Company has granted the underwriters a 45-day option to purchase up to an additional 232,500 ordinary shares at the public offering price of $4.00 per share, less underwriting discount and commissions. On March 28, 2018, the Company sold additional 232,500 ordinary shares for a gross proceed of $930,000. The total net proceeds from the above transactions were approximately $5.3 million.

These warrants will be non-exercisable and non-transferable for 180 days following March 19, 2018, the effective date of its prospectus. Such warrants will provide for cashless exercise in certain circumstances and shall terminate three years and six months after the effective date of its prospectus. On October 23, 2018, 63,645 warrants were exercised based on the Volume Weighted Average Price (“VWAP”) in September 2018 and in a cashless exercise. A total of 63,645 shares were issued. Restricted net assets The Company’s ability to pay dividends is primarily dependent on the Company receiving distributions of funds from its subsidiary. Relevant PRC statutory laws and regulations permit payments of dividends by Golden Bull WFOE, Shanghai Dianniu and Shanghai Baoxun only out of its retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. The results of operations reflected in the accompanying consolidated financial statements prepared in accordance with U.S. GAAP differ from those reflected in the statutory financial statements of Golden Bull WFOE, Shanghai Dianniu and Shanghai Baoxun. Golden Bull WFOE, Shanghai Dianniu and Shanghai Baoxun are required to set aside at least 10% of their after-tax profits each year, if any, to fund certain statutory reserve funds until such reserve funds reach 50% of its registered capital. In addition, Golden Bull WFOE, Shanghai Dianniu and Shanghai Baoxun may allocate a portion of its after-tax profits based on PRC accounting standards to enterprise expansion fund and staff bonus and welfare fund at its discretion. The statutory reserve funds and the discretionary funds are not distributable as cash dividends. Remittance of dividends by a wholly foreign-owned company out of China is subject to examination by the banks designated by State Administration of Foreign Exchange. As of December 31, 2018 and 2017, Golden Bull WFOE, Shanghai Dianniu and Shanghai Baoxun collectively attributed $0 and $0 of retained earnings for their statutory reserves, respectively.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Summary of Significant Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities Exchange Commission (“SEC”).
Principles of consolidation	Principles of consolidation The consolidated financial statements include the accounts of the Company, its subsidiaries, and their VIEs. All intercompany transactions and balances are eliminated upon consolidation.
Use of estimates and assumptions	Use of estimates and assumptions The preparation of 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 and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the periods presented. Significant estimates required to be made by management include, but are not limited to, useful lives of property, plant and equipment, deferred income tax and share based compensation. Actual results could differ from these estimates.
Foreign currency translation and transaction	Foreign currency translation and transaction The reporting currency of the Company is the U.S. dollar. The Company in China conducts its businesses in the local currency, Renminbi (RMB), as its functional currency. Assets and liabilities are translated at the unified exchange rate as quoted by the People’s Bank of China at the end of the period. The statement of income accounts are translated at the average translation rates and the equity accounts are translated at historical rates. Translation adjustments resulting from this process are included in accumulated other comprehensive income (loss). Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the results of operations as incurred. Translation adjustments were included in accumulated other comprehensive income (loss). The balance sheet amounts, with the exception of shareholders’ equity at December 31, 2018 and 2017 were translated at 6.8776 RMB and 6.5067 RMB to $1.00, respectively. The shareholder’s equity accounts were stated at their historical rate. The average translation rates applied to the consolidated statements of operatons for the years ended December 31, 2018, 2017 and 2016 were 6.6163 RMB, 6.7563 RMB and 6.6404 RMB to $1.00, respectively. Cash flows were also translated at average translation rates for the periods, therefore, amounts reported on the statement of cash flows will not necessarily agree with changes in the corresponding balances on the consolidated balance sheets.
Fair value measurement	Fair value measurement The accounting standard regarding fair value of financial instruments and related fair value measurements defines financial instruments and requires disclosure of the fair value of financial instruments held by the Company. The accounting standards define fair value, establish a three-level valuation hierarchy for disclosures of fair value measurement and enhance disclosure requirements for fair value measures. The three levels are defined as follow: ● Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. ● Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the assets or liability, either directly or indirectly, for substantially the full term of the financial instruments. ● Level 3 inputs to the valuation methodology are unobservable and significant to the fair value. The carrying amounts included in current assets and current liabilities are reported in the consolidated balance sheets as approximate fair value because of the short period of time between the origination of such instruments and their expected realization and their current market rates of interest. The long-term prepaid expense is approximate to its carrying value.
Revenue recognition	Revenue recognition On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09 Revenue from Contracts with Customers (ASC 606) using the modified retrospective method for contracts that were not completed as of January 1, 2018. This did not result in an adjustment to retained earnings upon adoption of this new guidance as the Company’s revenue was recognized based on the amount of consideration we expect to receive in exchange for satisfying the performance obligations. The core principle underlying the revenue recognition ASU is that the Company will recognize revenue to represent the transfer of goods and services to customers in an amount that reflects the consideration to which the Company expects to be entitled in such exchange. This will require the Company to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time, based on when control of goods and services transfers to a customer. The Company’s revenue streams are primarily recognized at a point in time. The ASU requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that the Company (i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, including variable consideration to the extent that it is probable that a significant future reversal will not occur, (iv) allocate the transaction price to the respective performance obligations in the contract, and (v) recognize revenue when (or as) the Company satisfies the performance obligation. The application of the five-step model to the revenue streams compared to the prior guidance did not result in significant changes in the way the Company records its revenue. Upon adoption, the Company evaluated its revenue recognition policy for all revenue streams within the scope of the ASU under previous standards and using the five-step model under the new guidance and confirmed that there were no differences in the pattern of revenue recognition. Transaction Fees Management Fees In applying judgment, the Company considered customers’ expectations of performance, materiality and the core principles of ASC Topic 606. The aforementioned revenues are recognized and the Company’s performance obligations (control of services) are generally transferred to the customers at the time of loan issuance. The Company’s contracts with borrowers generally do not include any variable consideration. Sales taxes
Incentives	Incentives In order to incentivize lenders, the Company provides incentives to marketplace lenders, who commit a certain amount of money for a period of time. During the relevant incentive program period, the Company set certain thresholds for the lenders to qualify for the cash incentive. When a qualified investment is made by a lender, the incentive payment is paid to the lender as a percentage of investment amount at the time of loan issuance as part of its investment to the specified loan that he/she has invested. The incentive expenses are recognized in our selling expenses in the accompanying consolidated statements of operations and comprehensive loss. These expenses amounted to $2,191,498, $1,497,279 and $503,238 for the years ended December 31, 2018, 2017 and 2016, respectively.
Servicing Expense	Servicing Expense Servicing expenses are paid by the Company to a third party platform provider on each deposit made by the lenders into their respective fund accounts held by the third party platform fund accounts. The amount of these expenses is based upon the deposit amount. The servicing expenses are recognized in our selling expenses in the accompanying consolidated statements of operations and comprehensive loss. These expenses amounted to $134,374, $205,604 and $105,386 for the years ended December 31, 2018, 2017 and 2016, respectively.
Verification, credit assessment and the decision-making processes costs	Verification, credit assessment and the decision-making processes costs Costs related to verification and credit assessment are recognized in the selling expenses in our accompanying consolidated statements of operations. Costs related to the decision-making processes are recognized in the general and administration expenses in our accompanying consolidated statements of operations. These expenses are immaterial to our consolidated statements of operations for the years ended December 31, 2018, 2017 and 2016.
Cash, cash equivalents and restricted cash	Cash, cash equivalents and restricted cash Cash, cash equivalents and restricted cash consist of cash on hand, demand deposits, short-term investment placed with banks or other financial institutions and have original maturities of less than six months and restricted cash, deposit of $600,000 was to fund an escrow account established for purpose of indemnifying the underwriter of the initial public offering in March 2018 as restricted cash for 30 months, which was classified as non-current assets as of December 31, 2018. Cash and cash equivalents also consist of funds earned from the Company’s operating revenues which were held at a third party platform fund accounts which are unrestricted as to immediate withdrawal and use.
Property and equipment	Property and equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method after consideration of the estimated useful lives and estimated residual value. The estimated useful lives are as follows: Useful Life Estimated Residual Value Office equipment and furnishing 3-5 years 5 % Leasehold improvements Shorter of the remaining lease terms or estimated useful lives - The cost and related accumulated depreciation and amortization of assets sold or otherwise retired are eliminated from the accounts and any gain or loss is included in the consolidated statements of operations and comprehensive loss. Expenditures for maintenance and repairs are charged to earnings as incurred, while additions, renewals and betterments, which are expected to extend the useful life of assets, are capitalized. The Company also re-evaluates the periods of depreciation and amortization to determine whether subsequent events and circumstances warrant revised estimates of useful lives.
Impairment for long-lived assets	Impairment for long-lived assets Long-lived assets, including property and equipment with finite lives are reviewed 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 value of an asset may not be recoverable. The Company assesses the recoverability of the assets based on the undiscounted future cash flows the assets are expected to generate and recognize an impairment loss when estimated discounted future cash flows expected to result from the use of the asset plus net proceeds expected from disposition of the asset, if any, are less than the carrying value of the asset. If an impairment is identified, the Company would reduce the carrying amount of the asset to its estimated fair value based on a discounted cash flows approach or, when available and appropriate, to comparable market values. As of December 31, 2018 and 2017, no impairment of long-lived assets was recognized.
Deferred rent	Deferred rent The Company leases office space and apartment units under operating lease agreements. Certain lease agreements contain scheduled rent increases, tenant improvement allowances or free rent clauses during the term of the lease which are recorded as deferred rent liabilities. Deferred rent liabilities represent the cumulative amount charged to operations under these leases in excess of the amounts paid and was included in prepaid expenses. Rent expense is amortized on a straight-line basis to operating expense over the applicable lease term.
Research and development	Research and development Research and development costs, which include the salary of the Company’s research and development department and benefit and website development cost, are expensed as incurred.
Advertising costs	Advertising costs Advertising costs are expensed as incurred and included in selling expenses. These expenses amounted to $431,734 ,$460,351 and $373,510 for the years ended December 31, 2018, 2017 and 2016, respectively.
Income taxes	Income taxes The Company accounts for income taxes in accordance with U.S. GAAP for income taxes. Under the asset and liability method as required by this accounting standard, the recognition of deferred income tax liabilities and assets for the expected future tax consequences of temporary differences between the income tax basis and financial reporting basis of assets and liabilities. Provision for income taxes consists of taxes currently due plus deferred taxes. The charge for taxation is based on the results for the fiscal year as adjusted for items, which are non-assessable or disallowed. It is calculated using tax rates that have been enacted or substantively enacted by the balance sheet date. Deferred taxes are accounted for using the asset and liability method in respect of temporary differences arising from differences between the carrying amount of assets and liabilities in the consolidated financial statements and the corresponding tax basis used in the computation of assessable tax profit. Deferred tax liabilities are recognized for all future taxable temporary differences. Deferred tax assets are recognized to the extent that it is probable that taxable income will be available against which deductible temporary differences can be utilized. Deferred tax is calculated using tax rates that are expected to apply to the period when the asset is realized or the liability is settled. Deferred tax is charged or credited in the operations of statement, except when it is related to items credited or charged directly to equity. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. An uncertain tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Penalties and interest incurred related to underpayment of income tax are classified as income tax expense in the period incurred. PRC tax returns filed in the year ended December 31, 2018 and 2017 are subject to examination by any applicable tax authorities.
Non-controlling Interest	Non-controlling Interest Non-controlling interest mainly consists of an aggregate of 6.8% (amended from 10.8% on December 4, 2017 as a result of a former Shareholder of Shanghai Dianniu transferred its 4.0625% equity interest to a Shanghai Dianniu Participating Shareholder) of the equity interests of Shanghai Dianniu held by two entities. The non-controlling interests are presented in the consolidated balance sheets, separately from equity attributable to the shareholders of the Company. Non-controlling interests in the results of the Company are presented on the face of the consolidated statements of operations as an allocation of the total income or loss for the year between non-controlling interest holders and the shareholders of the Company.
Earnings (loss) per share	Earnings (loss) per share Basic earnings (loss) per share are computed by dividing income (loss) available to ordinary shareholders of the Company by the weighted average common shares outstanding during the period. Diluted earnings (loss) per share takes into account the potential dilution that could occur if securities or other contracts to issue common shares were exercised and converted into common shares. As of December 31, 2018 and 2017, there were no dilutive shares.
Employee benefits	Employee benefits The full-time employees of the Company are entitled to staff welfare benefits including medical care, housing fund, pension benefits, unemployment insurance and other welfare, which are government mandated defined contribution plans. The Company is required to accrue for these benefits based on certain percentages of the employees’ respective salaries, subject to certain ceilings, in accordance with the relevant PRC regulations, and make cash contributions to the state-sponsored plans out of the amounts accrued. Total expenses for the plans were $325,086, $260,451 and $159,352 for the years ended December 31, 2018, 2017 and 2016.
Non-employees stock based conpensation	Non-employees stock based conpensation Share-based payment transactions with non-employees shall be measured at the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable.
Recently issued accounting pronouncements	Recently issued accounting pronouncements In February 2016, the FASB issued ASU 2016-02,“Leases” to provide a new comprehensive model for lease accounting. Under this guidance, lessees and lessors should apply a “right-of-use” model in accounting for all leases (including subleases) and eliminate the concept of operating leases and off-balance sheet leases. This guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact on its consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In June, 2018, the FASB issued ASU No. 2018-07 to provide guidance to reduce cost and complexity and to improve financial reporting for share-based payments issued to non-employees (for example, service providers, external legal counsel, suppliers, etc.). The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements. The Company does not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the Company’s consolidated balance sheets, statements of operations and comprehensive loss and statements of cash flows.
