Bitcoin miner profitability has reached record lows, with miner hash price falling below $36 per petahash per second (PH/s), according to a recent Blocksbridge report. This drop is primarily due to reduced block rewards following the recent halving and the increase in Bitcoin mining difficulty, which hit a new all-time high of approximately 90.6 trillion on August 1, 2024. Although Bitcoin's price has rebounded since the sharp decline on August 5, the miner hash price remains around $40 PH/s, still 10% lower than the previous all-time low in July 2024. Large public mining companies like Marathon Digital Holdings (MARA), Core Scientific, and Riot Platforms are facing challenges, with all-in monthly mining costs exceeding $60,000 per Bitcoin, making profitability difficult at current hash prices. Different strategies are being employed by these companies, with MARA and Riot holding their Bitcoin in hopes of future appreciation, while Core Scientific continues to liquidate its mined Bitcoin to cover operational costs.
