I will infiltrate the world's largest mining plant digging Bitcoin, a virtual currency that continues to soar, to approach the awful reality of mining sites that overwhelm 25,000 machines

Virtual currency "Bitcoin (bit coin)"The system is maintained by the act of" mining "which allocates new bit coins to the calculation process which consistently records the transaction record in the transaction register which is distributed and stored around the world. The world's largest mining factory's virtual currency mining site that continues digging bit coins with a tremendous number of special machines to see what kind of bit coin mining is at the forefrontQuartzI am covering it.

Mining factory in Bitmain in Ordos City, Inner Mongolia Autonomous Region of China. Mining of bit coins is done in 7 out of 8 factories. Bitmain is headquartered in Beijing City which is 400 miles away from the Ordos Factory (about 640 kilometers), but it is said that he acquired a well-established mining factory in Ordos city where electricity is cheap due to coal in 2015 .


The appearance of the factory. I do not know well what stupid factory group is "making" as far as it sees from the outside.


There are 25,000 machines in total for digging bit coins. The machines are arranged neatly in the rack.


A huge fan for measures against heat generated in large quantities is to cool the air in the factory and cool it.


It seems that one remaining factory is digging a virtual currency called Litecoin.


Power supply unit


Mining virtual currency requires huge amount of power, so we supply power to the machine with an outlet with a fuse box. Bitmain's Ordos factory's electricity bill is $ 39,000 a day (about 4.3 million yen).


Employee checking the operation of the machine. In eight factories, 50 employees are working.


It seems that you are managing whether the machine that overutilizes to the limit is functioning normally.


Employee cleaning the shelves. The factory is in a 24-hour posture and continues digging the virtual currency without rest.


The state of the headquarters adjacent to the factory. We manage the factory.


The transformer is operated in a building separate from the factory.


The key to access the transformer.


Dedicated machines equipped with chips called ASIC are operated with full operation, so it is often that they break down. Easy restoration work is done at the work site.


The following image is the packing material of the machine. To replace broken machines, it seems that a lot of new machines are being introduced each day.


A state of maintenance. The task of returning the machine to the shelf is hard labor.


Hou Jie who maintains the mining machine. Jie of 24 years old just graduated from college. He said he is living together with seven employees.


A worker who makes dinner.


I will take meals together by all means.


Bitcoins that 1 BTC exceeds 4000 dollars (about 440 thousand yen) and the market price keeps rising, new coins of 7 million dollars (about 770 million yen) are produced by mining a day. Bitmain is one of the top minor occupying 4% of the bit coin network. If you dig a bit coin and aim for a cash-over, you will have to fight against many enemies of the Bitmain class in China.
