# Bitcoin Hashrate Reclaims 1 Zettahash Despite AI Data Center Conversions

The seven-day average hashrate hit 1,000 EH/s amid a 5.9% difficulty jump, supported by mid-tier expansions and hardware resales.

## At a glance

- **What happened:** Bitcoin's seven-day average hashrate returned to 1 zettahash per second, prompting a 5.92% difficulty jump on Oct. 16 with another increase estimated.
- **Why it matters:** Network competition is rising rather than softening, as secondary buyers and steady miners offset capacity diverted to AI facilities.
- **Who is affected:** Bitcoin mining operators, hosting providers, and high-performance computing data centers.
- **What's next:** The next automated difficulty adjustment is estimated to adjust upward by roughly 5.16% around late October.

## Key points

- Bitcoin's seven-day moving average hashrate reclaimed 1,000 EH/s (1 ZettaHash), touching its highest mark since March 3.
- Network mining difficulty rose 5.92% on Oct. 16, with block times signaling an estimated 5.16% increase at the next adjustment.
- Bitdeer grew combined self-mining and co-mining capacity by 9.5 EH/s across September, reaching a total footprint above 110 EH/s.

## Editorial remark

- **Context:** Public miners have increasingly transitioned grid capacity to artificial intelligence and HPC workloads, displacing an estimated $1.5 billion worth of ASIC compute power. Instead of shrinking the network footprint, displaced equipment is being picked up by secondary hosts and mid-sized operators.
- **Impact:** Operational miners face intensifying competition and thinner operational margins as network difficulty climbs through consecutive upward adjustments, neutralizing expectations that AI conversions would ease mining difficulty.
- **Watch:** The upcoming difficulty adjustment estimated around Oct. 29, projected to climb approximately 5.16% based on prevailing block production rates.

Bitcoin's aggregate compute power has rebounded above 1 zettahash per second (1,000 EH/s) on a seven-day moving average, marking its highest operating level since March 3 [1]. The expansion comes despite large public mining firms repurposing power infrastructure and data centers for high-performance computing (HPC) and artificial intelligence workloads [1]. At the time of writing, $BTC traded at $81,082.

The computational recovery is directly tightening mining economics. The network executed a 5.92% mining difficulty increase on Oct. 16, with block production pacing toward an estimated 5.16% upward adjustment roughly seven days later [1]. This sustained network activity has wiped out the margin relief that remaining miners anticipated after public operators began offloading hardware capacity—displacing roughly $1.5 billion in hardware value alongside a 52% quarterly surge in direct HPC and AI revenues across the sector [1].

## Hardware Redistribution Absorbs Public Miner Exits

Replacement capacity is arriving through continuous self-mining additions and distributed secondary markets [1]. Bitdeer expanded its operational footprint across September, elevating self-mining capacity to 82.3 EH/s from 79.9 EH/s in August, while its co-mining segment increased to 28.7 EH/s from 21.6 EH/s—adding a combined 9.5 EH/s in a single month [1]. Bitdeer is also pursuing AI opportunities without winding down dedicated Bitcoin operations [1].

Concurrently, displaced equipment is returning online via smaller operators capitalizing on lower power rates abroad and hosted rack space [1]. Following Core Scientific's termination of a 15 EH/s chip contract with Block and Proto Global in the second quarter—which triggered a $41.9 million recorded loss as the firm pivoted toward high-density colocation—retail hosting firms like Sazmining began advertising Proto immersion hashboards alongside secondary Antminer S21 XP units hosted in Texas and Paraguay [1]. While major publicly traded miners previously [expanded their enterprise fleets](https://basisdesk.news/news/bitcoin-hashrate-rebound-cryptoquant-nip-group), the current cycle reflects a hardware redistribution toward non-traditional and decentralized operators [1].
