BTC (Difficulty Adjustment Percentage Change (Glassnode)
What to know:
- Bitcoin mining difficulty rose to 144.4T, jumped 15%, the biggest percentage increase since 2021.
- Hashrate has recovered to 1 ZH/s from 826 EH/s, even as hashprice sits at multi year lows around $23.9 per PH/s.
Bitcoin mining difficulty has climbed to 144.4 trillion (T), up 15%, the largest percentage increase since 2021, when the China mining ban led to a major disruption, which followed a 22% upward adjustment as the network stabilized.
Difficulty adjustments measure how hard it is to mine a new block on the network. It recalibrates every 2,016 blocks, roughly every two weeks, to ensure blocks continue to be produced about every 10 minutes, regardless of changes in the hashrate.

The adjustment follows a 12% decline in difficulty after a drop in the bitcoin hashrate, which is the total computational power securing the network. Mining activity suffered its sharpest setback since late 2021 after a severe winter storm in the United States forced several major operators to scale back operations.
In October, when bitcoin reached an all-time high of around $126,500, the hashrate also peaked at 1.1 zettahash per second (ZH/s). As prices fell to as low as $60,000 in February, the hashrate dropped to 826 exahash per second (EH/s). Since then, the hashrate has recovered to 1 ZH/s while the price has rebounded to around $67,000.
At the same time, hashprice, the estimated daily revenue miners earn per unit of hashrate, remains at multi-year lows ($23.9 PH/s), squeezing profitability.
Despite this profitability pressure, large-scale operators with access to low-cost energy continue to mine aggressively. The United Arab Emirates, for example, is sitting on roughly $344 million in unrealized profit from its mining operations.
Well-capitalized entities that can mine efficiently are helping keep the hashrate elevated and resilient, even amid subdued bitcoin prices.
