Stronghold Digital Mining bought a coal-fired power plant to mine the cryptocurrency in an environmentally friendly way. The company will use as fuel – coal dumps in Pennsylvania, which were left after production.
Now spent coal releases carbon dioxide into the air, and aluminum, iron, manganese, and other toxic substances into the soil and groundwater.
The company noted that this is a profitable production in all respects: one bitcoin can be produced from 200 tons of such coal, or about $ 43 thousand at the current exchange rate.
The company continues to acquire coal-fired power plants and to date it has already vacated 400 hectares of land previously covered with waste material.
Stronghold Digital Mining plans to provide power to more than 20 thousand miners. At the same time, only the nearest coal dumps are enough for the continuous mining of cryptocurrency for 30 years.
