Bitcoin mining just became harder than ever while the money it pays per unit of work sank. The network now demands 150.84 trillion difficulty steps and processes at 1.05 zettahashes per second, figures recorded on 2 October 2025. At the same moment the hashprice slid under fifty dollars per petahash per second while bitcoin traded near one hundred eighteen thousand dollars, tightening margins across the industry.
Product staff plus compliance teams track the squeeze because every petahash earns less even though the coin price looks high. Difficulty jumped 5.97% in the day leading to block 917.324. The code recalibrates after every two thousand sixteen blocks, roughly fourteen days, to keep each block close to ten minutes apart, anchoring issuance and settlement cadence.
Market impact for Bitcoin mining
The outcome a “profit paradox”: the coin trades at a high dollar level yet each unit of hashing work costs more to deliver and earns fewer dollars. Hashprice is the revenue a miner secures for one petahash per second of work. The April 2024 halving cut the block subsidy from 6.25 to 3.125 bitcoin and still colours the arithmetic. The moving parts—bitcoin price, difficulty, hashprice, electricity price, ASIC joules per terahash and transaction fees—while noting that a spike in fees, a rally in bitcoin or a slowdown in hashrate growth would widen margins again.
The code will adjust difficulty again after the next two thousand sixteen blocks. Until then every mining firm besides compliance desk must recheck power contracts, machine efficiency tables and risk models against the benchmarks.
