Despite this adjustment, the average interval between blocks currently exceeds 11 minutes.

This latest drop in difficulty marks the second largest decline this year, following a more than 11% plunge on February 7. The primary cause was a sharp decrease in hash rate due to equipment shutdowns from a winter storm in the U.S. The recovery was equally swift.

The average total computing power of the network (a figure smoothed by a seven-day moving average) has been steadily declining since peaking in mid-October 2025.

During this period, the hash rate dropped from a record 1.15 ZH/s to 940 EH/s.

The nearly 8% reduction in Bitcoin's difficulty has led to a rebound in hash price to over $33 per PH/s per day. Industry experts consider an average breakeven point for miners to be around $40 per PH/s per day.

The current price of the first cryptocurrency is approximately $70,800 (CoinGecko). According to TheEnergyMag, among the 14 largest public mining companies in the U.S., only IREN and the Trump family-affiliated American Bitcoin Corp are profitable.

These calculations are based on corporate financial reports for the fourth quarter of 2025.

Amid pressure on the mining economy, industry participants are diversifying into more lucrative AI services and seeking other ways to enhance business profitability.
