Inside a Chinese #Bitcoin Mine - The Coinsman

The mining operation resides on an old, repurposed factory floor, and contains 2500 machines hashing away at 230 Gh/s, each. (That’s 230 billion calculations per second, per unit).
The place consumes a massive amount of electricity. The operators told me that the power bill of this specific operation is in excess of ¥400,000 per month (that’s about $60,000 USD).
The farm employs three people whose job it is to monitor the machinery and make sure that all the machines are working properly. They work around the clock, in three shifts, and do a walkabout of the floor once per hour to check everything.
