As we approach the end of 2025, Bitcoin mining has undergone significant transformations, with on-chain data highlighting a marked increase in mining difficulty, which has experienced a staggering 35% growth this year.
Bitcoin Difficulty Has Crossed 148 Trillion Hashes
This year has seen Bitcoin miners ramping up their operations, expanding their facilities, and adapting to the changing environment. According to data from Blockchain.com, the network’s Hashrate, which measures the total computational power dedicated by miners, has escalated significantly—from an average of 795.7 terahashes per second (TH/s) at the start of the year to a remarkable 1070.3 TH/s.
This surge in Hashrate has been accompanied by a series of record-setting performances, culminating in an all-time high (ATH) of 1,151.6 TH/s in October. Although there has been a slight decrease since that peak, the current level remains approximately 34.5% higher than at the beginning of the year.
The revenue for Bitcoin miners predominantly hinges on the block subsidy, which retains a stable BTC value outside of Halving events. As a result, miners are often reliant on price growth to enhance their income. Consequently, it is common to observe the Hashrate following the trend of Bitcoin’s price.
A closer look at the charts reveals that the Hashrate’s ATH coincided with a price peak in the cryptocurrency market, and its subsequent decline in parallel with the pullback in Bitcoin’s price is apparent. Despite Bitcoin’s year-to-date downturn, miners have demonstrated resilience, as the Hashrate continues to reflect an upward trend.
The relationship between Hashrate and mining difficulty is undeniable. As the Bitcoin Hashrate increases, so does the mining Difficulty. This metric, embedded in the blockchain’s code, dictates how challenging it is for miners to uncover the next block. The network adjusts mining Difficulty approximately every two weeks based on miners’ performance since the last adjustment.
Satoshi Nakamoto set a standardized block time of 10 minutes for the Bitcoin network. If miners are successful in adding blocks faster than this average, the network responds by increasing the Difficulty to maintain the standard.
Thus far in 2025, the rising trend in miner activity has prompted Bitcoin to consistently adjust its Difficulty upward, achieving new all-time highs in the process. Currently, Bitcoin Difficulty stands around 148.2 trillion hashes—a substantial increase from the 109.8 trillion hashes recorded at the year’s outset.
BTC Price
In terms of market performance, Bitcoin experienced a brief recovery, climbing above $89,000, but has since retreated to around $87,300, reflecting the volatility that remains prevalent in the cryptocurrency space.
