Bitcoin mining difficulty hits new all-time high at 136.04 T

On September 5, 2025, Bitcoin’s mining difficulty reached a new all-time high of 136.04 T, according to CloverPool. The metric jumped 4.9% since the last adjustment.

Mining difficulty reflects the computational power required to find a new block and directly affects miners’ profitability. At the same time, the network’s average hashrate rose to 995.38 EH/s.

Despite forecasts of a correction, the difficulty has continued climbing since August. Analysts warn that this trend benefits large pools and corporations, increasing centralization within the network.

Still, individual miners occasionally succeed. Between June and August, three solo miners found blocks using Solo CK, earning 3.125 BTC plus transaction fees. For example, on July 3, an anonymous miner discovered block #903,883 and received around $350,000 in rewards, while another earned over $330,000 on June 6.

Experts emphasize that such cases are exceptions, confirming that record difficulty makes mining more profitable for large-scale players.
