By the end of 2025, the Bitcoin network quietly crossed a historic threshold—the seven-day average total network hash rate consistently exceeded 1 Zetahash per second (ZH/s). This milestone officially ushers Bitcoin mining into the Zetahash era.
A hash rate of 1 Zetahash means the network is performing more than one sextillion (1,000,000,000,000,000,000,000) hash calculations per second, elevating network security to unprecedented levels. Yet behind this achievement lies a sobering reality: miners are seeing their profit margins squeezed to record lows, with revenue per unit of hash power dropping to historic depths.
Industry Turning Point: The Leap from Exahash to Zetahash
Just a few years ago, 1 Zetahash was considered an unattainable goal. Today, not only has it become reality, but it also stands as a symbol of the industrialization of Bitcoin mining. 1 Zetahash equals 1,000 Exahash—a surge not driven by chance, but by fundamental changes in the industry’s structure.
This leap is the result of relentless hardware upgrades by miners, global expansion of data centers, and massive capital investments. Traditional solo miners and small-scale operations have largely faded from the scene, replaced by industrial mining enterprises with professional operations teams and access to cheap energy sources.
This transformation has shifted Bitcoin mining from a "tech enthusiast’s pursuit" to a true energy-intensive infrastructure industry. However, greater scale has not translated into higher profits. Instead, the industry’s profit model now faces unprecedented challenges.
The Profit Squeeze: When Hash Rate Growth Diverges from Revenue
As the network’s hash rate soars, revenue per unit of hash power moves in the opposite direction. According to industry data, in November 2025, the key metric for miner income—hashprice (daily revenue per unit of hash rate)—fell to a historic low of about $35 per PH per day.
This figure is far below the historical average and remained depressed through year-end. Miner income has entered one of the tightest ranges on record.
Two main factors drive this trend: First, the price of Bitcoin has not kept pace with hash rate growth; second, the block subsidy was reduced in the 2024 halving. Since April 2024, the reward per block dropped from 6.25 BTC to 3.125 BTC, and transaction fees have not made up for the lost income.
For most of 2025, transaction fees accounted for less than 1% of total block rewards—a stark contrast to the early days of Bitcoin mining.
Survival Threshold: Shutdown Price Becomes the Miner’s Lifeline
Given today’s mining difficulty, the shutdown price has become a critical survival metric for miners. Take the widely used Antminer S21 series from Bitmain, for example. With electricity priced at $0.08 per kWh, the breakeven point is roughly between $69,000 and $74,000 per Bitcoin.
This means if Bitcoin’s price falls below $69,000, miners using these machines will be operating at a loss.
As of February 5, 2026, the Bitcoin price on Gate stands at $69,300—right at this sensitive threshold. At this price, many miners are on the edge of profitability, with even minor price fluctuations threatening to force shutdowns.
More efficient mining rigs can lower the shutdown price, but their high upfront costs create new financial barriers, further intensifying the industry’s "Matthew effect"—the strong get stronger, while weaker players are pushed out.
Behind the Numbers: The End of Solo Mining and the Dilemma of Hash Rate Democratization
For individual miners, the barrier to entry in Bitcoin mining has become insurmountable. The current network difficulty is about 146.4 trillion (T), with a hash rate of 1.1 ZH/s.
A mainstream ASIC miner like the Antminer S21 (200 TH/s) contributes only a minuscule fraction of the total network hash rate.
Calculations show that, at current difficulty, a standard miner (100 TH/s) would need about 5,778 days—nearly 16 years—to mine a single Bitcoin. Even with a high-efficiency device like the Antminer S21 XP (480 TH/s), it would still take several years.
This makes solo mining virtually unprofitable, highlighting the stark contrast between Bitcoin’s ideal of decentralization and the reality of increasing hash rate concentration. The industry’s industrialization is now irreversible; in the Zetahash era, hash rate competition has become a capital-intensive game.
Market Ripple Effects: How Miner Behavior Impacts Bitcoin Price
The profit pressures facing miners not only affect their own survival but also create ripple effects in the Bitcoin market. When Bitcoin’s price stays below critical shutdown levels, weaker miners may be forced to sell their reserves to stay afloat, adding downward pressure on prices.
At the same time, miner shutdowns lead to a drop in network hash rate, triggering an automatic reduction in mining difficulty, which improves profitability for the remaining miners—a self-adjusting mechanism.
However, this adjustment process often brings increased market volatility. Especially after the halving, with lower block rewards and depressed transaction fees, miners have become exceptionally sensitive to Bitcoin’s price.
As of February 5, 2026, the market is at a delicate equilibrium. Any breakout in price direction could prompt collective action among miners, amplifying market swings.
Industry Evolution: Seeking New Survival Strategies in the Zetahash Era
Faced with profit pressures, the Bitcoin mining industry is searching for new survival strategies. Optimizing energy costs has become a core competitive advantage, prompting miners to migrate to regions rich in renewable energy and low electricity prices.
Meanwhile, mining hardware is evolving rapidly, with energy efficiency now the top priority. The latest generation of mining rigs boasts energy efficiency below 20 J/TH, compared to over 100 J/TH for earlier models.
Diversified revenue streams are also emerging. Some miners are repurposing excess heat for greenhouse farming or district heating; others participate in grid demand response, temporarily shutting down during peak usage to receive compensation.
For ordinary investors, direct participation in mining is now out of reach. Major platforms like Gate offer a more convenient way to get involved. Investors can trade Bitcoin and other cryptocurrencies directly on Gate, avoiding the need for hardware investment, high electricity costs, and complex operations, while also managing price volatility risks more effectively.
Looking Ahead: The New Normal for Bitcoin Mining in the Zetahash Era
The arrival of the Zetahash era marks a new level of industry maturity for Bitcoin mining, but also signals fresh challenges. With the continued impact of the 2024 halving and the next halving expected in 2028, miners will need to fundamentally rethink their profit models.
Looking forward, several trends may emerge: hash rate will continue to concentrate among large enterprises with capital and energy advantages; mining will integrate more deeply with energy systems, serving as a flexible load for grid management; transaction fees will play a larger role as block rewards decline further.
For the Bitcoin network as a whole, Zetahash-level hash rates provide unmatched security, making attacks prohibitively expensive. But this security comes at the cost of mounting pressure on miner profitability.
Striking a balance between the ideal of network decentralization and the economic sustainability of the industry will be the central challenge for Bitcoin in the Zetahash era.
Outlook
With the Bitcoin network’s hash rate surpassing 1 Zetahash/s, mining has entered a new era. At the same time, mining difficulty has climbed to 146.4 T, and revenue per unit of hash power has dropped to historic lows, leaving miners with razor-thin margins.
As Bitcoin’s price hovers near $69,000 on February 5, 2026, many mining farms using the S21 series are struggling on the edge of profitability. Since 2023, Bitcoin’s mempool was completely cleared multiple times in 2025, and transaction fees have become almost negligible.
In the future, miners who can secure the lowest-cost energy, operate the largest-scale farms, and deploy the most efficient hardware will dominate this fierce hash rate competition.
