ORGANIZATION AND NATURE OF BUSINESS	Note 1. ORGANIZATION AND NATURE OF BUSINESS Founded in the United States (the “U.S.”) in 2001, Sino-Global Shipping America, Ltd., a Virginia corporation (“Sino-Global” or the “Company”), is a global shipping and freight logistics integrated solution provider. The Company provides tailored solutions and value-added services to its customers to drive efficiency and control in related steps throughout the entire shipping and freight logistics chain. The Company conducts its business primarily through its wholly-owned subsidiaries in the People’s Republic of China (the “PRC” or “China”) (including Hong Kong) and the U.S. where a majority of the Company’s clients are located. The Company operates in three operating segments including (1) shipping agency and management services, which are operated by its subsidiaries in the U.S.; (2) freight logistics services, which are operated by its subsidiaries in the PRC; (3) container trucking services, which are operated by its subsidiaries in the U.S. On April 10, 2019, the Company entered into a cooperation agreement with Mr. Weijun Qin, the Chief Executive Officer of a shipping management company in China, to set up a joint venture in New York named State Priests Management Ltd. (“State Priests”), in which the Company will hold a 20% equity interest. On July 26, 2019, the Company signed a revised cooperation agreement with Mr. Weijun Qin which changed the Company’s equity interest in State Priests from 20% to 90%. The Company has not provided any cash contribution to the joint venture and there has been no operation of the joint venture pending the International Ship Safety Management Certificate from the China Classification Society (the “Certificate”). Sino-Global Shipping New York Inc. started providing shipping management related services that do not require certification which includes arranging and coordinating for ship maintenance and inspection this quarter. On November 6, 2019, the Company signed a revised cooperation agreement with Mr. Weijun Qin to restructure their equity interest in State Priests. Given that State Priests failed to timely obtain the necessary approval from related authorities, Mr. Weijun Qin agreed to exchange 80% equity interest in Sea Continent Management Ltd. (“Sea Continent”), another New York entity Mr. Qin owns for the Company’s 90% equity interest in State Priests. The equity transfer has been consummated. Sea Continent already has the Certificate but has no operations as of June 30, 2020. There has been no capital injection nor operations of State Priests and Sea Continent as of June 30, 2020, therefore no gain or loss has been recognized in the transaction. There has been no operation for Sea Continent for the year ended June 30, 2021. On January 10, 2020, the Company entered into a cooperation agreement with Mr. Shanming Liang, a shareholder of the Company, to set up a joint venture in New York named LSM Trading Ltd., in which the Company holds a 40% equity interest. No investment has been made by the Company as of the date of this report. The new joint venture will facilitate the purchase agricultural related commodities in the U.S. for customers in China and the Company will provide comprehensive supply chain and logistics solutions. There has been no operation for LSM Trading for the years ended June 30, 2021 and 2020. After the close of the stock market on July 7, 2020, the Company effected a l-for-5 reverse stock split of its common stock in order to satisfy continued listing requirements of its common stock on the NASDAQ Capital Market. The reverse stock split was approved by the Company’s board of directors and stockholders and was intended to allow the Company to meet the minimum share price requirement of $1.00 per share for continued listing on the NASDAQ Capital Market. As a result all common stock share amounts included in this filing have been retroactively reduced by a factor of five, and all common stock per share amounts have been increased by a factor of five. Amounts affected include common stock outstanding, including those that have resulted from the stock options, and warrants that convert to common stock. On July 31, 2020, the Company deregistered Longhe Ship Management (Hong Kong) Co., Limited (“LSM”) which is 100% own by Sino-Global Shipping (HK) Ltd. (Hong Kong). LSM has not been in operation or carried on business after June 30, 2018. The result of operations of LSM was immaterial for the years ended June 30, 2020 and 2019. On December 14, 2020, the Company incorporated a new entity named “Blumargo IT Solution Ltd.” with 80% ownership in partnership with Tianjin Anboweiye Technology Co. to build up hi-tech and information-based logistic services to meet the higher and complicate demand of customers. On June 30, 2021, the company increased the ownership to 100%. On March 19, 2021, the Company established a wholly owned entity of named “Cullinan Global Logistics Inc” which was set up to support its freight logistics services in the U.S. The Company dissolved Cullinan on June 28, 2021. There was no material operation for the year ended June 30, 2021. Starting from March 2021, the Company started cryptocurrency mining. The Company plans to leverage information technology and other innovative technologies in its business platform. These types of technology may be helpful in expanding its traditional logistics service expertise. Starting from March 2, 2021, the Company accepts Bitcoin as a form of payment for its global shipping, freight, and logistics services. Payments made in Bitcoin will be made at the rate applicable at the payment date. On March 2, 2021, the Company entered into a purchase agreement (the “Agreement”) with Hebei Yanghuai Technology Co., Ltd. (“Yanghuai”) for the purchase of 2,783 digital currency mining servers. The total gross purchase price was $4.6 million. The total computing power will reach 50,440 t/s. After the transaction is completed, Yanghuai will manage and operate the servers at Yanghuai’s site with no further charge from March 10, 2021 through March 9, 2022, after which time Sino-Global may engage Yanghuai to continue providing service for a fee. The first cash payment of approximately $0.9 million was paid within 15 days after the date of signing the Agreement. The second cash payment of approximately $0.9 million will be paid within 15 days after the date of acceptance of the servers and a special VAT invoice provided by Yanghuai. The remaining payment of approximately $2.8 million will be paid in 5 quarters within 10 days following the filing of Form 10-K or Form 10-Q for each of the Company’s financial quarters ending March 31, 2021, June 30, 2021, September 30, 2021, December 31, 2021 and March 31, 2022, subject to reductions if Yanghuai fails to meet the monthly committed net profit. Over the last two month, national and local governments in China have gradually restricted and banned cryptocurrency mining operations, causing owners of servers like the Products to cease operations. The Company has been advised that the operation of the mining has been paused by the Seller, which had continued to operate the Products on behalf of the Registrant. Based on amended agreement signed by the Company and Yanghuai on September 17, 2021, the Company is not liable for rest of the contract price and has title to half of the products. The Company recorded impairment for the mining equipment in the last quarter of 2021 in the amount of approximately $0.9 million. On March 24, 2021, the Company agreed to acquire a 60% ownership of Super Node LLC, which is a blockchain infrastructure developer and service provider, in cash or stock transaction for $5.0 million subject to valuation. The transaction is subject to the satisfaction of warranties and representations under the purchase agreement. Due to recent regulation of Bitcoin in China, the Company has paused the acquisition. On April 13, 2021, the Company formed a joint venture in which the Company owned 99% equity interest of Hainan Saimeinuo Trading Co., Ltd., in the free tax zone in Hainan Province, China, with a register capital of approximately $1.5 million. This subsidiary primarily engages in freight logistics services. On April 21, 2021, the Company entered into a cooperation agreement with Mr. Bangpin Yu to set up a joint venture in U.S. named “Brilliant Warehouse Service Inc” to support its freight logistics services in the U.S. The Company has a 51% equity interest in the joint venture. The outbreak of the novel coronavirus (COVID-19) starting from late January 2020 in the PRC has spread rapidly to many parts of the world. In March 2020, the World Health Organization declared the COVID-19 as a pandemic and has resulted in quarantines, travel restrictions, and the temporary closure of stores and business facilities in China and the U.S.. Given the rapidly expanding nature of the COVID-19 pandemic, and because substantially all of the Company’s business operations and its workforce are concentrated in China and the U.S., the Company’s business, results of operations, and financial condition have been adversely affected for the year ended June 30, 2021. The situation remains highly uncertain for any further outbreak or resurgence of the COVID-19. It is therefore difficult for the Company to estimate the impact on the business or operating results that might be adversely affected by any further outbreak or resurgence of COVID-19.
