Deposits on Equipment

During the year ended December 31, 2021, the Company paid approximately $274.8 million as deposits, primarily for miners, and, as of December 31, 2021, had reclassified $46.7 million to property and equipment in connection with the receipt of 23,864 miners at the Coinmint Facility and the Whinstone Facility. See Note 5, “Revenue from Contracts with Customers”.

During the year ended December 31, 2020, the Company purchased 33,646 model S19, S19-Pro, and S19j-Pro Antminers from Bitmain for a total purchase price of approximately new miners totals $76.1 million, including $6.6 million paid for the 3,043 miners delivered during the year ended December 31, 2020, $31.9 million paid as deposits in deposits during the same period, and the remaining $37.6 million due to be paid during the year ending December 31, 2021. As of December 31, 2020, the Company had received 3,043 of the new miners, including all 1,040 model S19 miners and 2,003 model S19-Pro miners, but had not yet received 30,603 of the new miners, including 18,603 model S19-Pro miners and all 12,000 model S19j-Pro miners. The 30,603 were delivered in monthly shipments through January 2022. Accordingly, the Company recorded the $31.9 million paid during the year ended December 31, 2020 for these outstanding miners as a deposit, which includes these miners on the accompanying consolidated balance sheet. (See Note 7, “Investments in Marketable Equity Securities” for additional details.)

During December 2019, the Company purchased 4,000 Bitmain model S17-Pro Antminers from Bitmain for approximately $6.3 million. The Company had received 3,000 of these model S17-Pro miners by December 31, 2019, and, accordingly, they were recorded as assets on the Company’s consolidated balance sheet for the year ended December 31, 2019. However, 1,000 of these S17-Pro miners were not received until February 2020. Therefore, as of December 31, 2019, the Company recorded the $1.4 million paid in advance for these 1,000 model S17-Pro miners as a deposit on the accompanying consolidated balance sheet.

Security Deposits

During the year ended December 31, 2021, the Company paid approximately $3.1 million in connection with an amended and restated Transmission/Substation Facility Extension Agreement for the construction of the Oncor-owned Delivery System facilities to serve the expansion of the Whinstone Facility. The deposit can be returned in two tranches: 1) upon verification by Oncor that the load demand meets or exceeds 394 MW, approximately $1.3 million can be returned, and 2) upon verification by Oncor that the load demand meets or exceeds 725 MW, the remaining $1.8 million can be returned. As of December 31, 2021, the Company has security deposits totaling approximately $5.0 million, including its ground lease of $1.8 million.
