Quarnot came up with a very innovative idea where you can heat your room and mine coins at the same time. The heater is actually a computer and will warm as soon as you begin mining (you can also use it as a heater without mining). The default coin the device will mine is Ethereum and will set you back $3600.
I'm assuming sales of this device in countries around the equator will be negligible.
