Bitcoin miners faced a 7.96% hike in difficulty on June 12, 2025, when block height 905184 was reached—pushing the number up to 126.27 trillion.
Snagging BTC just got trickier. Saturday’s difficulty tweak pushed the level 7.96% higher, marking the ninth time it’s climbed this year, alongside five times it’s been dialed down. The difficulty figure is dimensionless—it simply shows how much tougher it is to discover a block now compared to Bitcoin’s easiest setting, which was pegged at difficulty 1 when the network launched. With the current level at 126.27 trillion, miners must crank out, on average, 126.27 trillion hashes to hit a winner that matches the network’s target and qualifies as a valid block. Before the adjustment, bitcoin mining brought in roughly $64.03 per petahash per second (PH/s). But following the difficulty bump, the hashprice slipped to $59.01.
