[Report: Bitcoin Miners Facing the Most Challenging Profitability Environment in History] BlockBeats News, December 2 – According to Miner Weekly, Bitcoin miners are currently facing the most challenging profitability environment in history. The significant price correction of Bitcoin in November caused mining revenue to drop from approximately $55/PH/s in Q3 to about $35/PH/s, which is below the average total cost of $44/PH/s for major public mining machines. With the network hash rate approaching 1.1 ZH/s, the cost per hash better reflects the actual returns under the current mining difficulty. Even for the latest mining machines, the payback period exceeds 1,000 days, far longer than the approximately 850 days remaining before the next halving.
