The indicator reached 136 T, increasing pressure on miners.
The average hash rate of the network was 995.38 EH/s.
The centralization of mining raises new concerns for the industry.
On September 5, 2025, the difficulty of Bitcoin mining reached a new historical high of 136.04 T, according to data from CloverPool. Thus, since the last update, the indicator has jumped by 4.9%.
The mining difficulty reflects the average computational power required to find a new block and directly impacts the profitability of miners.
The previous maximum was recorded by analysts in August, after which the metric continued to rise contrary to experts' forecasts of a possible correction. At the same time, data shows that the average network hash rate reached 995.38 EH/s.
The increase in mining difficulty forces industry participants to constantly increase their capacities, making mining increasingly capital-intensive, experts note. In their opinion, the biggest advantages are gained by large mining pools and corporations, reinforcing the trend towards centralization in the asset ecosystem.
At the same time, analysts point out that even against the backdrop of overall dominance of institutional players, individual miners can still succeed. From June to August 2025, three solo miners mined blocks through the Solo CK service, receiving a reward of 3.125 BTC and fees.
Yes, on July 3, an unknown miner mined block #903 883, which brought the miner about $350,000 in rewards. Additionally, on June 6, 2025, another network participant mined a Bitcoin block and earned over $330,000.
However, these cases remain rare. Experts believe they rather confirm the rule that in conditions of record difficulty, mining is more profitable for large companies.
Recall that we wrote that an analyst warned of the threat of a Bitcoin collapse due to mining centralization.
