Bitcoin Mining Difficulty Ends 2025 at Record 148.2T as Next Hike Looms in Early 2026

Faster block production is pushing difficulty higher, pressuring miners.

Overview

  • The next difficulty recalibration is expected on January 8, 2026, with projections pointing toward roughly 149 trillion.
  • Average block times are running near 9.95 minutes, indicating blocks are being found slightly faster than the 10-minute target.
  • Rising thresholds are squeezing mining margins and increasing pressure on smaller or less efficient operators, encouraging consolidation.
  • Higher difficulty raises the cost of any coordinated majority attack, strengthening the network’s security posture.
  • Operators are adjusting as a recent ~4% hashrate dip and Bitmain’s December hardware discounts signal shifting equipment demand.
