Local disruption tests Bitcoin’s global resilience
Bitcoin’s mining system is under pressure, but the impact is unfolding unevenly across regions. Iran’s hashrate fell by 77%, losing about 7 EH/s and dropping almost 2 EH/s, according to the Global Hashrate Heat Map Q2-2026 updateshowing how quickly geopolitical risks can wipe out capacity in energy-dependent hubs.
However, the network response is more important than the loss itself. The global hashrate fell 5.8% to around 1,004 EH/s and has stabilized at around 960 EH/s, indicating limited systemic impact despite a sharp regional collapse.
Despite issues increasing by 3.87%, block production remained close to the 10-minute target, resulting in stable issuance. Meanwhile, the displaced hashrate shifted to dominant regions, with the United States accounting for 37.4% and Russia 16.9%.
In turn, resilience persists, but this redistribution concentrates mining power, which can determine future network risk and control dynamics.
Miners’ stress increases as profits shrink
Miner behavior is starting to change as profitability shrinks, and the signals are now moving together. First, the miner’s net NUPL fell from over 0.4 to 0.2. This implied that gains fell as Bitcoin fell from above $110,000 to almost $70,000. At the same time, the realized price rose to $64,000, reducing margins and increasing operational pressure.
As pressure increases, miners reduce their reserves. Assets have fallen to around 1.8 million BTC and continue their steady decline from over 3.3 million BTC. This reflects continued distribution to cover costs, increasing market supply, especially during periods of low prices.
However, the response is not uniform. A slower decline in reserves occurs when the price stabilizes, indicating that stronger miners are holding on while weaker miners are exiting. In turn, the market absorbs mixed flows, with forced selling creating pressure, while reduced issuance from miners can limit the downside.
Overall, the Iran-linked hashrate decline demonstrated the fragility of mining, but Bitcoin remains stable as redistribution absorbs shocks, making long-term supply dynamics uncertain.
Final summary
- Bitcoin is absorbing regional hashrate shocks as global power hovers around 960 EH/s, but rising concentration could change the long-term dynamics of mining control.
- BTC miners’ stress is causing the reserve to drop to 1.8 million BTC as tight margins increase selling pressure while stronger players limit the downside of supply.
