Report: Bitcoin mining is so profitable in China that miners will make money as long as bitcoin is worth more than $6,925
Context & Ripple Effects
Chinese industrial mining has been scaling toward this moment since at least 2015, when [[a:826247|Motherboard toured factory operations pulling in roughly $1.5M a month on about 3% of network hashrate]]. By early 2018 the economics were formalized: Bloomberg puts the breakeven bitcoin price for Chinese miners at $6,925, meaning profitability hinges almost entirely on electricity costs rather than hardware or coin price optimism.
That cost structure is exactly what later coverage stress-tested. Bitmain booked $3.5B in 2017 revenue as equipment sales boomed alongside cheap Chinese mining, but by October 2018 a Diar analysis found rising electricity costs had made mining unprofitable for everyone except the biggest operators — and by 2021 the geography itself collapsed when China's crackdown sent miners hunting for cheap power abroad.
First-order effects
- Chinese mining operations face a hard floor of $6,925 per bitcoin: any price move below that line flips their margins negative immediately, making them hypersensitive to volatility rather than long-term holders.
- Equipment makers like Bitmain sit downstream of that sensitivity — if miners' economics tighten at $6,925, new ASIC purchases are the first budget line cut.
Second-order effects
- The thin margin between breakeven and market price pushes consolidation toward the largest players with the cheapest power contracts, which is precisely the pattern Diar documented when costs rose and only the biggest operators stayed profitable.
- Cheap Chinese power becomes a competitive weapon in itself: miners bid for whatever low-cost electricity they can lock up, foreshadowing the global scramble for underpriced energy once domestic supply was constrained.
Third-order effects
- When a country hosts mining capacity built on sub-$6,925 economics, policy risk becomes the dominant variable — China's eventual crackdown forced an exodus toward cheap power in places like Kazakhstan, proving location arbitrage can be revoked overnight.
- If the pattern holds, mining structurally migrates to wherever marginal electricity is cheapest and most politically stable, with the median cost curve ratcheting upward over time as less efficient operators drop out.
The trend: Bitcoin mining is consolidating from distributed hobbyist-scale operations into a capital- and power-intensive industry whose viability is set by electricity costs and host-country politics rather than bitcoin's price alone.
