A second environmental impact is the air pollution attributable to coal-fired electricity era, and a 3rd is the e-waste because of the brief life expectancy of bitcoin-mining gear. One such environmental effect is that it worsens climate change. One research discovered that from 2016 to 2021, each US dollar value of bitcoin mined prompted 35 cents value of local weather damage, comparable to the beef industry and the gasoline business. When burned, coal and natural gas emit greenhouse gases, which heat

Earth and change the local weather. 0.1% of world greenhouse fuel emissions. This is because bitcoins are made using electricity partially generated by gas and coal-fired energy plants.
