Note 1.  Organization


Riot Blockchain, Inc. (the “Company” or “Riot Blockchain”) was originally organized on July 24, 2000, as a Colorado corporation.  Effective October 19, 2017, the Company's name was changed to Riot Blockchain, Inc., from Bioptix, Inc. Effective October 19, 2017, the Company changed its state of incorporation to Nevada from Colorado.


The Company operates a cryptocurrency mining operation, which utilizes specialized computers (also known as “miners”) that generate cryptocurrency (primarily bitcoin) from the Blockchain. The Company acquired approximately 8,000 miners through its acquisition of Kairos Global Technology, Inc., (“Kairos”) in November 2017, and from Prive Technologies, Inc. (“Prive”) Blockchain Mining Supply & Services Ltd. (“BMSS”) in February 2018. During December 2019, the Company purchased 4,000 next generation Bitmain S17 Pro Antminers for approximately $6.3 million from BitmainTech PTE. LTD. (“Bitmain”). In December 2019, 3,000 miners were received at the Company’s Oklahoma City facility, and the remaining 1,000 miners were received in early 2020. During February 2020, all of the new generation miners were installed and operational. As part of this upgrade, due to power and infrastructure considerations, virtually all of the previously acquired miners were taken offline and their future use is being evaluated.
