  • The indicator reached 136 T, increasing pressure on miners.
  • The average network hashrate was 995.38 EH/s.
  • Mining centralization raises new concerns for the industry.

On September 5, 2025, Bitcoin mining difficulty reached a new all-time high of 136.04 T, according to CloverPool . That's a 4.9% jump since the last update. 

Mining difficulty reflects the average computing power required to find a new block and directly affects the profitability of miners.

The previous maximum was recorded by analysts in August, after which the metric continued to grow despite expert forecasts of a possible correction. At the same time, the data shows that the average network hashrate reached 995.38 EH/s. 

The growing complexity of mining forces industry participants to constantly increase their capacities, which makes mining increasingly capital-intensive, experts note. In their opinion, large mining pools and corporations receive the greatest advantages, strengthening the tendency towards centralization in the asset ecosystem.

At the same time, analysts point out that even against the backdrop of the overall dominance of institutional players, individual miners can still succeed. Between June and August 2025, three solo miners mined blocks through the Solo CK service, receiving a reward of 3.125 BTC and fees.

Thus, on July 3, an unknown person mined block #903,883, which brought the miner about $350,000 in rewards. In addition, on June 6, 2025, another network participant mined a bitcoin block and earned over $330,000.

However, these cases remain rare. According to experts, they rather confirm the rule that in conditions of record complexity, mining is more profitable for large companies.
