$BTC Bitcoin Mining 2025: Profitability, Hash Rate, and Energy Trends After the Halving

After the 2024 halving, Bitcoin mining entered its fifth epoch and block rewards were reduced from 6.25 BTC to 3.125 BTC. This forced miners to rethink their operations, optimize efficiency, reduce energy costs, and upgrade hardware to maintain profitability.

Cointelegraph Research, in collaboration with industry experts from Uminers, examines this transformation in its latest report. The analysis covers improvements in ASIC efficiency, corporate performance, geographic expansion, and new revenue models.

As miners adapt, Bitcoin enters a new era where institutional momentum and the adoption of sovereignty could redefine its role in the global financial system.

Despite the adverse financial impact of the halving, the hash rate of the Bitcoin network has continued to increase.

On May 1, 2025, the total computational power of the network reached 831 EH/s. Earlier in the month, the hash rate peaked at 921 EH/s, representing a 77% increase from the 2024 low of 519 EH/s.

This rapid recovery underscores the relentless drive of the industry to achieve efficiency, as major mining companies reinvest in modernizing their fleets and optimizing energy usage to maintain profitability.
