Video: Ever wondered what a large-scale Bitcoin mine looks like? Well this video allows you to step inside a Chinese factory where the equivalent of $11 million of the cryptocurrency is generated every single year. BBC Future has a wonderful article about the secret facility, hidden away in a tiny Chinese town "so high up in the mountains that you have to bring your own cans of oxygen". But while oxygen may be thin on the ground, there is high-speed internet and no shortage of number-crunching hardware to mine Bitcoin -- regardless of who invented it.
Take a look at what it looks like in the video above, and go read the feature, too.
