El Salvador is mining bitcoin using energy from volcanoes
just weeks after becoming the first country to accept cryptocurrency as legal tender. President Nayib Bukele tweeted Friday that the country had mined about 0.006 bitcoin, or $269, with geothermic power. El Salvador is known as the 'land of volcanos,' with more than 20 potentially active volcanoes. Geothermal sources provide over 20 percent of the country's energy. After passing a bill in June, El Salvador began accepting Bitcoin as legal tender on September 7.
