As Bitcoin miners drop off the network due to the crackdown in China, the algorithm adjusts mining difficulty down 28% to make the process more profitable
Context & Ripple Effects
China's crackdown on crypto mining, traced in the history of the country's dominance over bitcoin mining, pushed a large share of the global hashrate offline within weeks — enough to drag bitcoin below $30,000 by late June from its mid-April peak. Today's 28% difficulty reduction is the protocol's automatic counterweight: with fewer machines competing, each remaining miner earns more per hash.
First-order effects
- Miners who stayed online or can quickly reconnect see an immediate jump in profitability, since the same block rewards now spread across roughly 28% less competing computing power.
Second-order effects
- The improved economics accelerate the relocation race already underway, with miners hunting cheap power in nearby Kazakhstan and companies like Bit Digital shipping tens of thousands of rigs out of China toward Canada and the US.
Third-order effects
- China's share of global bitcoin mining looks set to shrink structurally rather than temporarily — sources later estimate around 20% of the world's miners remain in the country after moving operations underground, suggesting the crackdown permanently redraws the network's geographic map.
The trend: State pressure on mining is redistributing bitcoin's hashrate from China toward jurisdictions with cheap power and clearer rules, with the difficulty algorithm smoothing the transition for whoever relocates fastest.
