Bitcoin Difficulty Breaks Records, Making Rewards Tougher Than Ever
New data shows that Bitcoin's mining difficulty has increased for the 11th time this year, up 1.42% on Friday night, making it even harder to earn block rewards. Despite five separate drops, Bitcoin's mining difficulty in 2025 is still up 17.73%.
129.44 Trillion: Bitcoin's All-Time Difficulty
Earning Bitcoin block rewards has become more difficult after the network difficulty increased by 1.42% on Friday to block 909,216. This brought the difficulty to 129.44 trillion, the highest in the network's history.
In simple terms, 129.44 trillion represents the average number of hashes that miners need to solve to successfully find a new block. Bitcoin's mining difficulty adjusts roughly every two weeks (every 2016 blocks) to keep the block time around 10 minutes, regardless of the network's available computing power.

With record hashrate, blocks are processed faster than usual, which is the reason for the latest difficulty increase. If the block time is less than 10 minutes, the system reduces the difficulty level. There have been 16 difficulty changes since the beginning of 2025, starting on January 12, with a slight increase of 0.61%.
Of these changes, 11 increased by 34.27%, while five decreased by 16.54%. This means that Bitcoin mining difficulty has increased by 17.73% since the beginning of the year. The latest increase also slightly reduced the hashrate.
After reaching a record 976 exahashes per second (EH/s) on August 8, the hashrate has dropped to 965.97 EH/s. It is too early to make precise predictions about the next reassignment on August 29, 2025, but current data suggests a possible difficulty reduction of 1.77%.
Bitcoin mining difficulty continues to push for records in 2025, thanks to unprecedented hashrate levels and frequent adjustments. In the lead-up to the next reset, miners are racing harder for block rewards while also watching for signs of difficulty decreasing or increasing later in the month.
