Bitcoin Mining Difficulty Reaches All-Time High as Hashprice Declines - BTC Network Analysis

Bitcoin mining difficulty surged 5% to an unprecedented 150.84 trillion on Wednesday, representing the seventh consecutive upward adjustment according to Glassnode data. The difficulty metric, which recalibrates every 2016 blocks (approximately bi-weekly), determines how hard miners must work to discover new blocks while maintaining the 10-minute average block time. This increase mirrors continued expansion in Bitcoin's network hash rate, now exceeding one zettahash at 1.05 ZH/s. Higher hash rates indicate more mining equipment competing to secure the blockchain, enhancing network security while simultaneously raising profitability thresholds. Mining profitability pressure is evident in hashprice data from Luxor, showing miner revenue per hashrate unit has fallen below $50 per petahash per second. The metric briefly reached $52 when BTC traded above $118,000 earlier this summer but has declined alongside increasing difficulty and softening prices. For miner margins to recover, three key factors would need improvement: higher transaction fees (currently at multi-year lows), a Bitcoin price rebound, or a network hash rate slowdown. Despite record difficulty and declining hashprice, mining stocks have rallied with Bitcoin's surge above $118,500, with Cipher Mining (CIFR) up 51% monthly, Bit Digital (BTBT) gaining 25%, and Marathon Digital (MARA) climbing 16%.
