Inside Chinese factories that mine 4050 bitcoins/month, equivalent to about $1.5M, with computing power that amounts to roughly 3% of the bitcoin network
Inside the Chinese Bitcoin Mine That's Making $1.5M a Month — In October of last year Motherboard gained access to a massive …
Context & Ripple Effects
When Motherboard walked through this facility in early 2015, a single Chinese operation hashing ~3% of the entire network was still novel enough to warrant a factory tour. The visit captured bitcoin mining mid-transition from hobbyist garages to industrial sites, with the economics resting on one input: cheap local power.
The arc since then runs straight through Bitmain, which grew to control 29% of the Bitcoin hash rate while selling rigs to everyone else, and ends with Beijing's May 2021 ban scattering the industry — though sources estimate roughly 20% of the world's miners stayed in China underground. This mine is the template both eras were built on.
First-order effects
- At 2015 prices, one site pulling in $1.5M a month proves the cost advantage of Chinese electricity and hardware access is decisive — mining margins are set by where you plug in, not by how cleverly you operate.
- Operators at this scale become price-setters in their own right: a single facility contributing ~3% of global hash rate can sway block-reward distribution toward whoever controls industrial power contracts.
Second-order effects
- Equipment suppliers capture more value than miners themselves — Bitmain's path from rig maker to hash-rate giant to $3.5B in 2017 revenue shows the picks-and-shovels layer consolidating faster than the mines it supplies.
- Mining's power appetite becomes a policy problem: by 2021 analysts put annual consumption around 91 TWh, roughly 0.5% of global electricity — growth of that magnitude inevitably draws state scrutiny of exactly the concentrated geography this mine exemplifies.
Third-order effects
- Geographic concentration of mining turns it into a regulatory target rather than a diffuse market activity — the 2021 Chinese ban forced the model underground or offshore, restructuring an industry that had optimized itself into one jurisdiction.
- If profitability stays tied to cheap power (Bloomberg's reporting pegged Chinese miners' breakeven near $6,925 per bitcoin), the long-run structure is mining migrating perpetually toward subsidized or stranded energy — with each relocation resetting who holds hash-rate leverage.
The trend: Bitcoin mining industrializes wherever electricity is cheapest — concentrating in Chinese factories like this one until regulation pushes it underground or across borders.
