Argentine presidential candidate Sergio Massa has received criticism from the country's cryptocurrency community for a proposal to mine Bitcoin using excess natural gas from the Vaca Muerta oil fields. The proposal was presented by computer scientist Santiago Siri and would involve using surplus gas from Vaca Muerta, a major shale oil and gas deposit in western Argentina, to power bitcoin mining operations. While the project has its proponents, Bitcoin miners and advocates have expressed skepticism, arguing that BTC mining is too complex and competitive for the government to get involved. Critics suggest that private-public partnerships may be a better alternative model if the state wishes to participate.
