Bitcoin mining difficulty falls 10% in 11th largest downward adjustment

Bitcoin mining difficulty has undergone its second-largest downward adjustment this year, following February’s 11% shift. Mining difficulty fell by 10.09% on Sunday, easing some of the pressure on miners as the blockchain recorded its 11th-largest downward adjustment.

Difficulty drop and key figures

Galaxy Research said mining difficulty declined from 138.96 trillion to 124.93 trillion at block 953,568 on Sunday. The move represents the second biggest drop of 2026 and a 20% decrease from the level reached at its peak in November.

What drove the adjustment

Galaxy Research attributed the adjustment to changes in network hashrate. It said the epoch—the period between difficulty adjustments—ran for 15.6 days, above the typical 14 days, as hashrate came offline.

Mining difficulty is designed to keep block production stable even as the amount of mining power on the network changes. As a result, the latest drop means miners will have an easier time finding blocks, reflecting reduced competition tied to the falling hashrate.

Market context and miner economics

The report also linked the difficulty adjustment to broader market conditions. Galaxy said the price of Bitcoin (BTC) has fallen by around 15% so far in June, which has “squeezed miner margins.”

Hashprice and expected impact on profitability

Following the difficulty dip, Hashprice returned to above $30. Hashprice—an estimate of how much a miner can expect to earn from a specific quantity of hashrate—rose 13% to $33 per Petahash per second per day, according to Hashrate Index.

The Energy Mag reported that this level is an important threshold because it pushes more miners toward a gross breakeven point. It added that efficient fleets of miners should continue generating profit at a lower hashprice, while older-generation machines with higher electricity costs are likely to be turned off.
