Bitcoin hashprice falls 9.4% after 3.12% difficulty rise

Bitcoin miner revenue fell 9.44% after a 3.12% rise in difficulty to 136.61T; hashprice dropped to $35.29 per PH/s as BTC slid from above $82,000 to $76,680.

On May 15 at block height 949,536 the Bitcoin network’s mining difficulty increased 3.12% to 136.61 trillion. It was the first upward adjustment in more than a month, the fourth difficulty increase of 2026 and the third-largest adjustment so far this year.

Hashprice, the estimated daily dollar value of 1 PH/s of hashing power, declined from $38.97 on May 14 to $35.29 by May 18, a drop of 9.44%, based on hashrateindex.com data. The fall reflects both the higher difficulty and a weaker bitcoin market price.

Bitcoin’s price moved from an intraday high above $82,000 on May 14 to about $76,680 as of 3 p.m. ET on May 18. Transaction fees accounted for 0.59% of total block rewards over the most recent 24-hour period.

Network computational power briefly passed 1,000 exahashes per second on May 11 and measured about 959.03 EH/s as of 3:30 p.m. ET on May 18. Average block times were roughly 10 minutes and 12 seconds at press time, and there were 1,576 blocks left in the current difficulty epoch, making the next adjustment likely around May 29.

The combination of higher difficulty and lower hashprice reduced the estimated dollar revenue miners receive per unit of hashpower. Changes in network difficulty or bitcoin’s market price will change that estimated revenue.
