In October 2014, Motherboard gained access to a massive, secretive Bitcoin mine housed within a repurposed factory in the Liaoning Province in rural northeast China. This is the infrastructure that keeps the digital currency’s decentralised network up and running, and its operators are profiting big time.
The mine is just one of six sites owned by a secretive group of four people, part of a colossal mining operation that, as of 2015, cumulatively generated 4,050 bitcoins a month, equivalent to a monthly gross of $1.5 million.
The narration is in Mandarin, with subtitles provided in English. An interesting watch that offers a glimpse of what bitcoin mining in China is like.
