Bitcoin Mining Heats Home For Free In Siberia (qz.com)

Quartz has published a video on YouTube about two entrepreneurs who have figured out how to heat their homes for free by mining bitcoin. The "miner" -- that is, the machine mining the bitcoins -- warms up liquid that is then transferred to the underfloor heating system. The cottage has two miners, which bring in about $430 per month from processing bitcoin transactions -- all while keeping the 20 square meter space warm.
