BITCOIN MINING FOR AMERICA

Riot Blockchain, Inc. is a Bitcoin mining company, supporting the Bitcoin blockchain through rapidly expanding large-scale mining in the United States. We are focused on expanding our operations by increasing our Bitcoin mining hash rate and infrastructure capacity. Riot believes the future of Bitcoin mining will benefit from American operations and endeavors to be the driver of that future.

Bitcoin Mining

Our Bitcoin mining operations include both Whinstone U.S.’ facility in Rockdale, Texas and our hosted miners at Coinmint LLC’s Massena, New York facility. Whinstone U.S. is a wholly owned subsidiary of Riot Blockchain and consists of the single largest Bitcoin mining and hosting facility in North America, as measured by its 300 MW in developed capacity. Riot currently has a deployed hash rate capacity of 2.2 EH/s utilizing approximately 73 megawatts (MW) of energy.

Riot has 3,600 more S19 scheduled for deployment by the end of September 2021 which is expected to increase our self-mining hash rate capacity to 2.6 EH/s, utilizing approximately 83 MW of energy.
