Description about declining prices and price protection Due to declining prices and price protection included in the purchase agreement, the Company was able to take ownership of about 1,100 S17 Pro miners with a further payment of $71,640 upon delivery in November 2019. The Company also acquired approximately 400 Bitcoin mining machines from Bitmain in November 2019, for a total of approximately 1,500 Bitcoin mining machines all located in the Company's facility in LaFayette, GA. Once these Bitcoin mining machines were delivered and installed, the deposit was reclassified to property and equipment, and depreciation commenced over the 2-year estimated useful life using the straight-line method. All Bitcoin mining machines were placed in service during 2019, except approximately 600 which were placed in service in January 2020 upon delivery and installation of two additional containers.
