[JPMorgan: Total Market Value of 14 U.S.-Listed Bitcoin Mining Companies Reached $56 Billion in September, Setting a Record High] According to a report released by JPMorgan on Wednesday, cited by CoinDesk, the total market value of 14 U.S.-listed Bitcoin mining companies tracked by the firm surpassed $50 billion for the first time last month (September), reaching $56 billion, a month-over-month increase of 43%. The report noted that 12 out of these 14 mining companies outperformed Bitcoin itself in September. Meanwhile, the average Bitcoin network hash rate grew by 9% month-over-month in September, reaching 1031 EH/s. However, despite the rise in market value and hash rate, miners' profitability has been squeezed due to intensified competition in hash rate. The report estimates that miners' daily block reward revenue in September decreased by 10% month-over-month, while gross profit dropped by 17% month-over-month.
