Bitcoin Mining Difficulty Set to Reach New Peak as Hashrate Approaches Record Levels

Bitcoin’s mining difficulty is projected to increase by over 4%, reaching an all-time high near 126.95 trillion (T), reflecting a surge in mining activity and greater network security, even as transaction fees remain subdued.

This adjustment, expected to be confirmed within the next 100 blocks, will surpass the current difficulty record of 123T. At the start of 2025, the difficulty was at 109T, showing significant growth over the past months, according to Coinwarz.

The rise in difficulty corresponds with a steady climb in the Bitcoin network’s hashrate—the total computing power dedicated to mining—now averaging 918 exahashes per second (EH/s) over seven days. This marks a notable increase from 840 EH/s two weeks ago and edges close to the previous peak of 925 EH/s, hinting that a new record could soon be set.

Despite the expansion in mining power, transaction fees have remained remarkably low. Currently, the fee for a high-priority Bitcoin transaction is around 2 satoshis per virtual byte (sat/vB), roughly equivalent to $0.30. Miners continue to prioritize transactions with higher fees for quicker confirmations.

These developments highlight a divergence within the Bitcoin ecosystem: while mining infrastructure and security scale to new heights, on-chain transaction demand and fees continue to stay low, underscoring a complex dynamic between network growth and user activity.
