On March 21, following the latest recalibration, the difficulty of mining the leading cryptocurrency fell by 7.76% to 133.79 T.
Despite the adjustment, the average interval between blocks at the time of writing exceeds 11 minutes.
This recent drop in difficulty is the second largest of the year; on February 7, the parameter plummeted by more than 11%. The primary factor then was a sharp decline in hashrate due to equipment shutdowns caused by a winter storm in the United States. The recovery was equally swift.
The average total computational power of the network (a metric smoothed by a seven-day moving average) has been steadily declining since reaching a peak in mid-October 2025.
During this period, the hashrate fell from a record 1.15 ZH/s to 940 EH/s.
The reduction in Bitcoin’s difficulty by nearly 8% led to a rebound in hashprice to values above $33 per PH/s per day. Industry experts consider the average breakeven level for miners to be around $40 per PH/s per day.
The current quotes for the leading cryptocurrency are approximately $70,800 (CoinGecko). According to TheEnergyMag, among the 14 largest public mining companies in the US, only IREN and the Trump family-affiliated American Bitcoin Corp mine profitably.
The publication’s calculations are based on corporate financial reports for the fourth quarter of 2025.
Amidst economic pressures on mining, industry participants are diversifying into more lucrative AI services and seeking other ways to enhance business profitability.
