Another Adjustment: Bitcoin Mining Difficulty Increased by 6.81%
On the night of April 5, 2025, the Bitcoin network recorded another increase in mining difficulty, which rose by 6.81% to 121.50 T.
Bitcoin's hash rate reached its peak, rising to 883 exahashes per second (EH/s), an increase of approximately 21 EH/s compared to the previous record set on March 28.
According to analytical platforms such as BTC.com, this increase has become one of the most significant in recent months, reflecting the continued growth of the network's computational power. Mining difficulty, which determines the amount of calculations required to create a new block, directly affects miners' profitability and the stability of the Bitcoin ecosystem.

Bitcoin's mining difficulty is a metric that reflects how difficult it is to perform calculations to find a new block and receive a mining reward. The main goal of this adjustment is to maintain the average block discovery time around 10 minutes, regardless of changes in the overall network's computational power.
Approximately once every 14 days (every 2016 blocks), this value changes, regardless of the network's hash rate.
If finding a block takes less than 10 minutes, the difficulty increases; if it takes more time, the difficulty decreases. Mining difficulty depends on the network's hash rate and the time spent finding previous blocks. The higher the mining difficulty, the lower the profitability metric.
The current spot hash price—expected daily profit per petahash per second (PH/s) of SHA256 power—is $46.16 per PH/s. Hash price has fallen by 11.15% since March 5.
The next difficulty recalculation is expected in 14 days, approximately on April 19, 2025.
