Bitcoin mining enters the era of zettahash as profitability narrows


Bitcoin mining has crossed a historical limit at the end of 2025. According to a recent report from GoMining, the network has entered the era of Zettahash, surpassing 1 Zettahash per second of computing power.

But while the hash rate has risen to record levels, the profitability of miners has moved in the opposite direction. The result is a larger, more industrialized mining industry – and more exposed to price risks than at any point in this cycle.

Hash rate reaches record levels as mining expands

You see Report The Bitcoin network has maintained more than 1 ZH/s at a seven-day averagewhich represent structural change rather than temporary growth.

This growth reflects aggressive hardware upgrades, new data centers and the expansion of industrial operations. Mining no longer dominates They are the fringe players. Now it’s like the energy infrastructure.

As a result, competition for block prizes has increased dramatically.

Revenue per miner has declined despite network growth

As the hashrate increases, Revenue per computing unit fell to one of its narrowest ranges on record.

The report highlights that Miners’ profits increasingly depend on… Bitcoin price and difficulty alone. Other reserves have disappeared, including increased transaction fees and increased block support that had previously eased margin pressure

This pressure means that miners are now working on lower profit margins, even as they employ more capital and power.

According to the GoMining website, the collision was visible in Membok. For the first time since April 2023, the entire memory of Bitcoin was liquidated several times in 2025.

This means that Bitcoin network It was so quiet that transactions were cleared immediately, even with the lowest possible fees.

As a result, miners earned almost nothing from the fees and were forced to rely almost entirely on the price of Bitcoin and block support for revenue.

Transaction fees do not provide much relief after the split

The dynamic after the half increased the pressure.

With the support of mass reduced to 3,125 BTC, Transaction fees are not reimbursed for lost revenue. The report indicates that the fees constituted Less than 1% of total block rewards for most of 2025.

As a result, the mining economy is directly exposed to Bitcoin price fluctuations, with reduced internal stabilizers.

Hashprice hits new lows as profit margins remain under pressure

This pressure was clearly evident in the hash rate – the daily income earned per unit of hash rate.

According to the report, the sale price has fallen to an almost all-time low From $35 per PH per day in November It remained weak until the end of the year. He finished a close fourth $38which is much lower than historical averages.

This left little room for operational error.

Closing prices turn price levels into economic stimuli

These results are in close agreement with recent data Debtors’ closing prices.

To the current difficulty and the costs of electricity nearby From $0.08 per kWh, The S21 Series miners are largely approaching the breakeven point between $69,000 and $74,000 for Bitcoin (BTC).). Below this range, many operations cease to generate operating profits.

The most efficient and high-quality devices are still available at much lower prices. But the miners of the middle class faces immediate pressure.

Why is this important to the price of Bitcoin right now?

This does not create a price plan. Markets can trade below the breakeven point in mining.

However, it creates The behavioral threshold. If Bitcoin remains below key closing levels, weaker miners may sell their reserves, shut down equipment, or reduce exposure.

In a market already tight on liquidity, these actions can amplify volatility.

Bitcoin mining is stronger and more industrial than ever. But this scale comes with sensitivity. As the hash rate increases and fees vanish, it becomes The price is more important than For the stability of the metal.

This makes the levels like $70,000 It makes economic sense – not because the graphs show, but because of the cost structure in the network.
