Bitcoin mining difficulty hits $127B with record revenues in July

Bitcoin mining difficulty reached a record 127.6 trillion on 3 August 2025, signalling a new phase in the network’s technical development and operational demands.

According to CoinWarz data, the milestone was recorded at block 908,544 and represents a 9.12% increase over the past 30 days.

Over 90 days, the difficulty rose by 7.14%, driven by the integration of more efficient mining hardware and optimisation of mining operations.

This increase highlights Bitcoin’s self-adjusting protocol, which maintains a steady block production rate of one block every 10 minutes regardless of hashrate growth.

As computing power grows, difficulty rises proportionally to regulate coin issuance and maintain network stability.

Despite the higher technical threshold, Bitcoin miner revenues reached $1.66 billion in July — their highest post-halving monthly income since 2024.

Data shows the average revenue per exahash per day stood at $57,400, up 4% compared to June.

This trend suggests miners are successfully managing operational costs despite rising competition and complexity.

The sharp rise in mining difficulty is expected to continue driving professionalisation within the sector.

Less efficient miners may be forced out, as industrial-scale operations benefit from economies of scale and newer equipment.

A slight difficulty adjustment is projected on 9 August, with a 0.03% decrease expected to bring it to 127.29 trillion.

While marginal, this drop may offer temporary relief to smaller operations with tighter margins.

The recent disconnect between rising difficulty and increased revenue may point to a structural shift in mining economics, suggesting that the sector is finding new profitability models even amid intensifying competition.

At the time of reporting, BTC price was $113,735.
