Stronghold Digital Mining

Stronghold Digital Mining is a vertically integrated and environmentally beneficial digital asset miner based in Pennsylvania, USA.

Stronghold employs 21st-century crypto mining techniques to remediate the impacts of 19th- and 20th-century coal mining in some of the most environmentally neglected regions of the United States. Its Bitcoin mining operations are powered through the reclamation of coal refuse sites across Pennsylvania. They remove coal refuse from piles and burn it in an emissions-controlled manner at their wholly owned generation facilities.
