Bitcoin Mining Difficulty Drops 7.7% as Block Production Slows
The Bitcoin network automatically adjusts mining difficulty about every two weeks based on the pace of block production, aiming to keep the average block time near 10 minutes. A lower difficulty reduces the computing power miners need and eases cost pressures. As major mining companies pivot to AI computing and network hash rate fluctuates, the mechanism is particularly important for maintaining transaction confirmations and network stability.
The Bitcoin network lowered mining difficulty by about 7.7% on March 20, 2026, taking it to 133.79 trillion. Related reports calculated the decline at 7.76%, the second-largest drop of 2026. The adjustment followed average block times exceeding the 10-minute target, reflecting pressure on miners and a lower hash rate. The reduction is expected to speed up block production.

The history behind this eventBitcoin Mining Difficulty Drops 10%, Briefly Lifting Miner Revenue
The Bitcoin network automatically adjusts mining difficulty roughly every two weeks based on total network computing power to maintain an average block time of about 10 minutes. When BTC prices weaken, electricity and equipment costs can force less efficient miners to shut down. A downward difficulty adjustment reduces competition among active mining machines, affecting miners’ cash flow and network security.
On Sunday, July 19, 2026, Bitcoin mining difficulty fell 10.09% to 124.93 trillion, the second-largest decline this year and the 11th-largest on record. The network hashrate was down 23% from its October 2025 peak as cryptocurrency prices fell and some computing power went offline. Following the adjustment, short-term revenue per mining machine rose by about 9%, while hashprice returned to the $30-per-PH/s-per-day threshold.
Bitcoin Mining Difficulty Edges Lower but Is Expected to Rebound as Listed Miners’ Q1 Sales Hit Record
Bitcoin’s mining difficulty adjusts periodically with network hashrate to maintain the average block-production time. After the 2024 halving cut the block reward to 3.125 bitcoin, rising energy costs continued to pressure the profitability and treasury strategies of listed miners including MARA and Riot. Their bitcoin sales have also become an important indicator of the industry’s financial health.
Bitcoin mining difficulty fell about 1.1% in the latest adjustment to 135.5 T, but the market expects it to rise in the next adjustment in early May 2026. Listed miners including MARA and Riot sold more than 32,000 bitcoin in total during the first quarter of 2026, exceeding their combined sales for all of 2025 and setting a quarterly record.
