“The mine we visited is just one of six sites owned by a secretive group of four people, part of a colossal mining operation that, as of our visit, cumulatively generated 4,050 bitcoins a month, equivalent to a monthly gross of $1.5 million. Despite its dystopian appearance, the group’s six mining farms encompass eight petahashes per second of computing power, whose brute force, as of October, accounted for 3 percent of the entire Bitcoin network. If you’ve bought or sold or conducted any Bitcoin transaction recently, these are some of the folks you have to thank. Strangely, the mine’s workers actually live inside the facility itself, returning home just four or five days a month.”
