The cost of mining one Bitcoin has risen to $70,027, a significant increase from $67,704 earlier this year, according to recent disclosures from MARA Holdings. This rise is attributed to escalating energy prices, which have been climbing steadily. Despite the increased costs, Bitcoin's current trading price of $72,748 allows miners like MARA Holdings to remain profitable, although margins are tighter. MARA Holdings, a major corporate Bitcoin holder with 53,822 BTC, has adjusted its treasury policy to permit the sale of Bitcoin from its reserves in response to market volatility. The company's electricity costs alone have surged to $38,956 per Bitcoin, with total operating costs reaching $70,027. When including selling, general, and administrative expenses, the all-in production cost is estimated to be between $110,000 and $113,000 per Bitcoin.
