Bitcoin’s Dice Roll Just Got Tougher: Difficulty Climbs 5.97% in Third-Biggest Jump of 2025
By the numbers, Bitcoin’s network difficulty climbed 5.97% at block height 917,280, landing it the title of this year’s third-biggest jump.

Bitcoin miners had a modest September slump, watching revenue shrink 4.23%—that’s $69 million gone compared to August’s haul.
Bitcoin’s hashrate hit beast mode this week, flexing a record-smashing 1,109 exahash per second (EH/s) as the network cranked its computational biceps harder than ever. Meanwhile, Bitcoin’s hashrate fireworks are lighting up merge mined neighbors too, with Namecoin, Rootstock, and Fractal Bitcoin all hitching a ride on the rocket and scoring monster boosts of their own.
Although the network’s mining difficulty cranked up 4.63% just four days ago, that bump barely ruffled the miners. The machines kept churning with wild devotion, and the protocol’s horsepower blasted its way to a shiny new all-time high of 1,091 exahash per second (EH/s).
At an operating expense of $0.04 per kilowatt-hour (kWh), the current crop of SHA256 bitcoin miners sorts into a clear profit ladder, with high-hashrate hydro units setting the pace and a few efficient air and immersion options keeping things interesting.
BITF has taken off and the momentum isn’t fading. Is there a development the market’s quietly pricing in? Or is it time to re-rate the stock altogether?
