Bitcoin Mining Difficulty Ends 2025 at 148.2 Trillion

• Bitcoin closed the year with the mining difficulty level of 148.2 trillion, an increase of 35% from the same period last year.
• The level of difficulty reached 156.0 trillion in November and is forecasted to increase in early 2026.
• The increase in difficulties indicates better security of the network, even under the effect of halving in 2025 and price pressure.

The Bitcoin network closed out the year 2025 with a mining difficulty of 148.2 trillion, which was the final difficulty adjustment for that year and reflected continued growth.

“The figure illustrates the 35% increase from the 109.8 trillion that existed at the beginning of the year on January 1st, 2025,” which symbolical of the year of growth in spite of the fluctuations that occurred in the marketplace, as well as the Bitcoin halving that took place in 2025. Mining difficulty is one such metric that indicates the difficulty level in the discovery of a novel block, which is accomplished through Bitcoin mining. Bitcoin adjusts automatically every two weeks as per the difficulty level, regardless of any changes in hashrate or computing power.

This means that the higher the level of difficulty, the more miners in addition to increased powers working to secure the blockchain database.

A Year of Rising Difficulty

During 2025, Bitcoin’s mining difficulty has been steadily increasing due to the ongoing improvement in mining equipment. According to data from CoinWarz, the network reached its highest difficulty of the year at 156.0 trillion on November 11.

The trough in the final quarter was experienced towards the end of October, when difficulty saw a short drop to 146.7 trillion. Even so, the difficulty still showed considerable increases from the levels witnessed at the beginning of the year, which showed that miners managed to remain operational.

Based on the final adjustment, the level of difficulty stands about 5% lower than the November level, but this could be indicative of a weak slowing rather than a systemic trend away from mining.

Outlook for Early 2026

It is forecasted that when the next difficulty adjustment, which is anticipated to occur on January 8, 2026, happens, mining will rise due to a mining difficulty of about 149.3 trillion. This is a sign that the trend of increasing Bitcoin network security is on the right path

The projection indicates miners are still very confident in the long-term fundamentals of Bitcoin, thus willing to continue investing in infrastructure, even as block rewards were reduced after the 2025 halving.

Price and Difficulty Dynamics

The relationship between Bitcoin’s price and mining difficulty varied throughout the year. When difficulty reached its annual high in November, Bitcoin was trading near elevated levels. However, during earlier price highs, difficulty was notably lower, showing that hashrate growth does not always move in lockstep with price movements.

The relationship between the price of Bitcoin and mining difficulty has been variable this year. When difficulty was at its yearly high in November, Bitcoin was trading near highs. During earlier highs in price, however, difficulty was decidedly lower, which shows hash rate growth does not always correlate with price movements.

As of the end of 2025, Bitcoin is trading approximately 4% below its price at the start of the year. Despite this, mining difficulty continued to rise, reflecting miners’ ability to adapt through improved efficiency and lower operating costs.

Resilience After the Halving

A rising level of difficulty after a halvening incident is truly impressive. Traditionally, halvings have contributed to a rise in difficulty levels, thus pressuring miners by reducing block rewards. This led to inefficient miners withdrawing from the competition in 2025, while those that continued to operate remained.

As Bitcoin enters 2026 and difficulty values approach records, the system has never been more secure and competitive, making it the leading proof-of-work chain in the world.
