Bitcoin Hashrate Rises: What Does It Mean for Miners?

Bitcoin’s computing capacity has increased over the past month. A CoinWarz snapshot checked on October 26, 2026 showed estimated network hashrate of approximately 1.12 zettahashes per second, or ZH/s, up 13.84% over 30 days. The seven-day increase was only 0.51%, indicating that the monthly expansion had not continued at the same pace during the latest week.

For miners, additional computing power means greater competition for revenue. An operator running the same equipment can receive a smaller share of earnings when competitors add machines or deploy more efficient hardware.

Profitability ultimately depends on revenue per unit of computing power and the cost of producing it. A rising bitcoin price can help absorb higher costs, but expensive electricity, inefficient machines, and equipment financing can still leave an operator with shrinking margins.

Why More Hashrate Does Not Guarantee Higher Profits

Hashrate measures the number of computational attempts made to find a valid block. Operators increase capacity using application-specific integrated circuits, or ASICs, designed for mining. Bitcoin’s mining documentation explains how these machines repeatedly calculate hashes until they find a result that satisfies the network target.

Every machine competes with other devices performing the same task. Buying additional equipment can expand one operator’s output, but the benefit depends on how quickly competitors expand their capacity.

Consider a business that maintains its production capacity while all its competitors expand. It continues working at the same speed, yet its share of total production declines. The same relationship helps explain why rising network hashrate does not necessarily benefit every miner.

Comparisons also need consistent measurement periods. Daily estimates can fluctuate because blocks are not discovered at perfectly regular intervals. Multi-day averages and company operating data provide stronger evidence of capacity expansion than a single reading.

Difficulty Turns Capacity Growth into Revenue Competition

Bitcoin adjusts mining difficulty every 2,016 blocks to keep block production close to a ten-minute average. When a sequence of blocks is completed faster, the next adjustment increases difficulty. The mechanism is described in Bitcoin’s consensus documentation.

This prevents additional machines from permanently accelerating block production in the same proportion. After difficulty rises, each unit of computing power must perform more work to obtain an equivalent expected reward.

The CoinWarz difficulty dashboard checked on October 26 showed difficulty of approximately 140.58 trillion. The next adjustment occurs at block 973,728. Its calendar timing and size remain estimates until that block is reached.

Four Factors That Determine a Miner’s Margin

Greater competition affects operators differently. Their revenue, operating costs, and financing arrangements determine how much pressure they can absorb.

A. Bitcoin’s Price and Transaction Fees

Block revenue consists of the block subsidy and transaction fees. Its rupiah value also changes with BTC’s price and the conversion rate used. A miner can earn fewer bitcoin while receiving more rupiah if BTC’s value rises sufficiently.

More transactions do not necessarily produce a proportional increase in revenue. Fee contributions need to be checked directly because fees per transaction and competition for block space can change. Block reward components are explained in Bitcoin’s transaction and coinbase documentation.

B. Electricity and Operating Expenses

Electricity tariffs determine the cost of running equipment throughout the day. Cooling, hosting, maintenance, and labor add expenses beyond the machines’ direct power consumption.

Luxor’s analysis of electricity breakeven levels explains why the highest affordable power price differs by machine efficiency. Operators with cheaper electricity contracts have more room to continue operating when revenue falls.

C. Hardware Efficiency and Capital Spending

ASIC efficiency is commonly expressed in joules per terahash, or J/TH. Lower energy requirements for the same computational work help reduce electricity costs.

Replacing equipment still requires capital. Operating savings must be weighed against purchase costs, financing, useful equipment life, and the possibility that newer machines will offer better efficiency. Positive operating cash flow does not necessarily mean the original hardware investment has been recovered.

D. Mining Pools, Uptime, and Payment Terms

Many miners combine their computing capacity through mining pools to receive more regular payments than they would by waiting to discover blocks independently. Actual payments depend on the pool’s payout model, computational contributions, and service charges.

Connectivity problems and equipment outages reduce productive operating time. Two identical machines can generate different receipts if their uptime or payment arrangements differ.

A Small Revenue Decline Can Produce a Much Larger Margin Decline

A simple calculation illustrates the effect of difficulty. Every figure below is an illustrative assumption, not an actual machine’s performance or a mining profit forecast.

Assume:

• A machine consumes 4 kilowatts and runs for 24 hours daily.

• Electricity costs Rp1,500 per kWh.

• Initial gross revenue is Rp180,000 per day.

• Difficulty rises 10%, while machine hashrate, reward value, BTC’s price, and other components remain unchanged.

Daily consumption is 4 × 24 = 96 kWh, costing 96 × Rp1,500 = Rp144,000. The initial surplus over electricity is Rp180,000 − Rp144,000 = Rp36,000 per day.

Using an inverse relationship between expected revenue per hash and difficulty, revenue after the 10% increase becomes approximately:

Rp180,000 ÷ 1.10 = Rp163,636 per day.

The surplus over electricity falls to Rp19,636 per day, approximately 45.45% below the previous Rp36,000. Gross revenue falls much less than the remaining margin because the electricity bill stays unchanged.

The calculation excludes pool fees, cooling, repairs, depreciation, and equipment repayments. It illustrates margin sensitivity rather than net profit or an investment payback period.

Hashprice Provides a Clearer View of Revenue Conditions

Miners need a measure connecting computing capacity with earnings. Hashprice measures expected revenue from one unit of hashrate operated for one day, commonly quoted per PH/s per day in BTC or US dollars. Hashrate Index explains the definition and its components.

Rising network hashrate alongside falling hashprice indicates that computational competition is growing while revenue per unit of capacity is declining. Operators then need to compare hashprice with their actual cost per unit of computing power.

Network data alone does not reveal each company’s electricity tariff, debt, hedging arrangements, or cash reserves. Claims that margin pressure will force miners to sell BTC require additional evidence from company disclosures or reliably attributed transactions.

What Comes Next?

The difficulty adjustment at block 973,728 provides the next test of changes in network capacity. Several indicators should then be assessed together:

• Average hashrate measured over a consistent window.

• Hashprice in BTC and US dollars.

• Transaction fees as a share of block revenue.

• Miner production, operating costs, and financing requirements.

Price movements can be followed through the BTC/USDT market on MEXC. Trading prices describe the value of the bitcoin produced, while mining data explains the cost and competition involved in producing it.

Rising hashrate provides information about network capacity. For miners, survival depends on converting that capacity into revenue after expenses. If difficulty keeps rising while hashprice and efficiency fail to improve, operators with high costs and limited cash reserves will face the greatest pressure.
