There's an unexpected trend in one remote, frozen corner of the world - Grandma's are getting in to mining Bitcoin!

Considered one of the remote corners of the world, these grannies living deep in Siberia are mining Bitcoin - and loving it! Power is cheap and typically much of it is used to simply cool down the mining rigs. But where the snow never melts - keeping miners from overheating isn't a problem. The cost of a mining rig is paid for after the first 8-9 months, then it's all profit for these crypto-seniors.
