ETF Securities | The intelligent alternative | December 2017 | ETFS Outlook. Bitcoin valuation: Marginal cost by James Butterfill – Head of Research & Investment Strategy. The electricity consumption to mine Bitcoin is currently equivalent to roughly 600,000 households’ usage or US$3.4m spent every day, this will double by end-2018. Current mining costs for Bitcoin imply a marginal cost of production of US$2,250. Including rig purchase costs, marginal costs are US$4,300. Current Bitcoin prices appear to be justified only on the basis of mass adoption, which at this stage remains low.
