Bitcoin Hashrate Rebounds to 1.15 ZH/s After 7.8% Difficulty Drop

Bitcoin Mining Landscape in Late March 2026

As of March 29, 2026, the Bitcoin network demonstrates resilience amid challenging conditions. The total hashrate stands at 1.15 ZH/s (1,150 EH/s), with known reported hashrate at 1.03 ZH/s. 84 This marks a recovery from earlier lows below 950 EH/s following a significant difficulty adjustment. With BTC trading at $65,813, miners navigate post-halving economics, elevated energy costs, and emerging opportunities in AI infrastructure. 3

The network recently surpassed 20 million BTC mined, leaving just 1 million coins in rewards—a milestone underscoring mining's critical role in Bitcoin's security. 10

Sharp Difficulty Drop: March 20 Adjustment

Bitcoin's mining difficulty underwent a 7.76% reduction to 133.79 trillion on March 20, 2026, at block height around 941,472. This was the second-largest negative adjustment of the year, following February's 11.16% plunge. 15 20 Average block times had stretched to over 12 minutes, prompting the protocol's self-correcting mechanism to recalibrate for ~10-minute targets. 3

The drop reflects hashrate declines driven by factors like BTC prices dipping below $70,000, surging energy costs from geopolitical tensions (oil above $119), and miners powering down unprofitable rigs. 3 Hashprice hovered near $32/PH/s/day, near break-even for many ASICs. 6

The next adjustment is slated for April 3, potentially rising to 141.33T (+5.6%), signaling expected hashrate growth. 83

Hashrate Trends: Recovery Amid Pressures

March 2026 has been volatile for hashrate. It peaked near 1,083 EH/s early in the month before dropping nearly 12% to ~954 EH/s by mid-March. 43 By March 23, the 7-day SMA rose to 967 EH/s (+1.8% weekly). 29 The latest data shows further rebound to 1.15 ZH/s. 84

Contributing factors include:

Energy Shocks: 8-10% of hashrate sensitive to oil/gas prices amid Iran conflict.

3

Profit Squeeze: Margins at historic lows, with reports of $19,000 losses per BTC produced.

20

AI Pivot: Firms like Core Scientific, Riot Platforms, and Bitdeer reallocating rigs to HPC/AI, where margins exceed mining.

6

US dominates with ~37.5% global hashrate (~400 EH/s in Q1). 31 Emerging spots like Venezuela eye growth with energy surpluses. 67

Mining Pools: Foundry Leads Centralized Distribution

Pool hashrate remains concentrated, raising decentralization discussions. As of March 29: 84

| Pool | Hashrate | Share | Fee | |------|----------|-------|-----| | Foundry Digital | 338.87 EH/s | 29.3% | 0.01% FPPS | | AntPool | 185 EH/s | 16.0% | 0-4% | | F2Pool | 111.08 EH/s | 9.6% | 0-3.13% | | ViaBTC | 97.21 EH/s | 8.4% | 0-3.13% | | SpiderPool | 88.06 EH/s | 7.6% | 0.005% |

Foundry mined fewer expected blocks recently (-2.7), while AntPool gained (+3.5). 84 Concerns over single pools mining consecutive blocks persist. 2

Operations News: AI Shifts and Production Updates

Public miners report strains: CoinShares notes record-low margins, hashprice at $28-30/PH/s/day Q1. 11 49 Bitdeer scaled self-mining to 68 EH/s in Feb, producing 705 BTC (+541% YoY). 59 Canaan held 1,793 BTC treasury after Feb output. 51

Many pivot: Foundry eyes Zcash pool; others host AI. 77 Use Pickaxe's hosted mining solutions to avoid ops hassles.
