Bitcoin’s mining difficulty rose to 148.2 trillion in the final adjustment of 2025, with projections pointing to 149 trillion on January 8, 2026. Average block times are at 9.95 minutes, slightly below the 10‑minute target that triggers difficulty increases.
Throughout 2025, difficulty hit new all‑time highs, with sharp jumps in September before prices collapsed in October’s crash. Rising difficulty forces miners to deploy more computing power and energy to stay competitive.
The adjustment system safeguards decentralization by preventing any miner from dominating block production. This mechanism also defends against 51% attacks, ensuring predictable supply schedules regardless of total hashrate.
Network hashrate continues to climb, reflecting growing miner participation despite challenges. The next adjustment at block height 931,392 will recalibrate difficulty based on recent block times, maintaining Bitcoin’s decentralized structure and predictable issuance. #BTC #Mining $BTC
