Bitcoin and Zcash Mining Difficulty Increases. What About Profitability?

cryptonews.ruPublicado a 2026-09-07Actualizado a 2026-09-07

Resumen

The mining difficulty for both Bitcoin and Zcash has increased alongside rising cryptocurrency prices and heightened miner activity. Contrary to expectations, the profitability of mining these assets has not improved. Bitcoin's mining difficulty rose by 1.13% to 127.45 trillion, requiring miners to compute roughly that many hashes to add a block and earn 3.125 BTC (approx. $250k). This followed a surge in the global hash rate, which exceeded 1,000 EH/s and even reached 1,130 EH/s recently. Despite Bitcoin's price trading around $79.5k, the average mining profitability, as measured by the Hashprice Index, slightly decreased to $39.3 per day for 1,000 Th/s of equipment. Similarly, Zcash's price surged nearly 50% weekly, surpassing $1.2k. Its network hash rate and mining difficulty also hit record highs. However, this increased competition negated potential profit gains from the price rise. Mining revenue per megawatt-hour for a top-tier device actually fell from $727 in late August to $708 on September 4th, demonstrating that higher prices did not translate into better mining returns.

The mining difficulty for Bitcoin and Zcash, as well as miner activity, have increased following the rise in the coins' prices. Contrary to expectations, the profitability of mining these cryptocurrencies has not increased.

Bitcoin mining difficulty rose by 1.13% to 127.45 T (trillion) following the latest adjustment, which occurs approximately every two weeks, according to CoinWarz. This means miners need to compute an average of about 127.5 trillion hash functions to add one block to the Bitcoin network and receive the new 3.125 $BTC reward ($250k at the current rate) for it.

The increase in difficulty followed a rise in miner activity — the global total hashrate of mining equipment once again exceeded 1000 EH/s (exahashes per second), rising by 7.58% over the week. And on Sunday, September 6th, it reached 1130 EH/s for the first time since May 25th.

The Bitcoin price is also fluctuating above summer levels, returning to May's highs. As of 1:00 PM Moscow time on September 7th, $BTC is trading around $79.5k.

Meanwhile, the average mining profitability, reflected by the Hashprice Index, was $40 after the difficulty adjustment but fell to $39.3 by Monday. This is the daily amount of Bitcoin a 1000 Th/s (terahashes per second) unit of equipment can mine.

Zcash Mining

The situation in mining the privacy-focused cryptocurrency Zcash is similar. The coin updated its multi-year high on September 7th, with its price exceeding $1.2k. The asset gained almost 50% in a week.

Also on September 7th, the computational power (solrate) rose to a record 32.6 GSol/s (gigasols per second), and the mining difficulty for $ZEC reached a historical high of about 298 M (million). According to TheEnergyMag's estimates, the increase in hashpower that began on Friday was equivalent to turning on nearly 6,000 Bitmain Z15 Pro units and coincided with the deployment of new equipment.

Therefore, the rise in the price of $ZEC did little to change mining economic efficiency, the outlet notes. Mining Zcash on a single latest-generation device generated $727 per MWh at the end of August when the token was priced below $900. On September 4th, when the price exceeded $1000, the revenue per megawatt was $708 (-3%).

Preguntas relacionadas

QWhy did the mining difficulty for Bitcoin and Zcash increase?

AThe mining difficulty for Bitcoin and Zcash increased due to a rise in miner activity and the hash rate (computational power) of their respective networks, following the upward price movements of the coins.

QWhat is the current hashprice index for Bitcoin mining, and what does it represent?

AThe hashprice index for Bitcoin mining fell to $39.3 per day as of the report. This represents the estimated daily revenue in USD generated by a mining rig with a power of 1000 TH/s (terahashes per second).

QWhat was significant about the Bitcoin network's hash rate on Sunday, September 6th?

AOn Sunday, September 6th, the Bitcoin network's global hash rate reached 1130 EH/s (exahashes per second) for the first time since May 25th, indicating a significant surge in total mining power.

QDespite Zcash's price surge, what happened to the profitability of mining it?

ADespite Zcash's price surge to over $1,200, the profitability of mining it actually decreased slightly. The increased mining difficulty and network hash rate offset the higher coin price, leading to lower revenue per unit of mining power (e.g., revenue per MWh).

QWhat mining equipment is mentioned in relation to the recent increase in Zcash's hash rate?

AThe recent increase in Zcash's computational power (solrate) is associated with the deployment of new equipment, specifically mentioned as being equivalent to the activation of nearly 6,000 Bitmain Z15 Pro mining devices.

Bitcoin Price Erases October Gains: Why $81,300 is Now a Critical Level

Bitcoin continued its decline on Wednesday, dropping below $83,000 amid a broad market correction that saw several large-cap altcoins fall by 4% or more. This sell-off has effectively erased nearly all of the gains accumulated since the beginning of October, raising fresh doubts about the prospects for a traditional "Uptober" rally. According to the daily price chart, Bitcoin has been under pressure since Tuesday afternoon when it last traded above $86,000. While it initially appeared to hold support above $85,500, the price lost $1,500 in under 20 minutes, dropping to a level just above $83,800. A brief recovery to $84,000 was short-lived, with the price failing to hold that range by approximately 4:00 AM Eastern Time. The focus is now on the critical support level of $81,300 as the market watches for further direction.

Daniel Rhine Sentenced to 32 Months in Prison for Demanding 20 BTC Ransom from His Employer

Daniel Ryan, a 59-year-old key infrastructure engineer for a New Jersey industrial company, was sentenced to 32 months in federal prison on September 28 by Judge Michael A. Shipp in Trenton. Ryan, from Kansas City, Missouri, had pleaded guilty in April to two charges: one count of extortion involving a threat to damage a protected computer and another count of intentionally damaging a protected computer. The charges stemmed from an incident where he blocked access to the company's network and demanded a ransom of 20 BTC (worth approximately $750,000 at the time), threatening to disable more servers if his demands were not met.

Jury Finds Hacker from Uranium Finance Guilty, Who Spent Cryptocurrency Stolen in Hack on "Pokémon" Cards

A Manhattan federal jury found Jonathan Spalletto guilty of computer fraud and money laundering in the Uranium Finance case, as reported by Inner City Press. The verdict concludes a trial centered on smart contract errors, millions in cryptocurrency, and extravagant purchases, including collectible cards. Jurors deliberated from Tuesday afternoon and reached their decision on Wednesday. Prosecutors requested GPS monitoring for Spalletto, but Judge Jed S. Rakoff declined to impose additional conditions, citing Spalletto's consistent court appearances. A sentencing date has not yet been set. The indictment carries statutory maximum sentences of 10 years for computer fraud and 20 years for money laundering, though these represent upper limits, not a prediction of the final sentence.
