Bitcoin mining difficulty closes 2025 with a modest increase after three months of decline

Source: Yellow Original Title: Bitcoin Mining Difficulty Ends 2025 with Modest Increase After Three Months of Decline

Original Link: Bitcoin (BTC) mining difficulty increased by 0.04 percent to 148.26 trillion on December 25.

The adjustment ended a three-month downward trend.

Marks the last difficulty change of 2025 after the network reached an all-time high of 155.97 trillion on October 29.

What happened

Mining difficulty adjusts every 2,016 blocks to maintain Bitcoin’s target of one block every 10 minutes.

The metric increased by 35 percent in 2025, rising from 109.8 trillion at the start of the year to 148.26 trillion currently.

The network’s hashrate similarly grew by 34.5 percent over the same period. It reached a maximum of 1,151.6 terahashes per second in October before falling to around 1,070 terahashes per second.

October’s peak coincided with Bitcoin’s price hitting a record close to $124,000 on October 6. Since then, the price has fallen approximately 30 percent to around $87,000.

Reports indicate that Chinese authorities shut down mining operations in Xinjiang in mid-December. Rising winter energy costs in North America and lower Bitcoin prices also pressured miners.

Why it matters

Higher difficulty increases operational costs by demanding more computing power and energy per block.

The adjustment mechanism protects network decentralization by preventing a single miner from controlling block production.

Miners face increasing pressure as the hashprice fell to around $38 per petahash per second. This is roughly half the level observed after the block reward halving in April.
