Cryptocurrency mining takes a lot of energy, and anything that uses that much energy generates a lot of heat, which is why cooling systems are so important for computers using high-end graphics cards. But what if instead of cooling down your mining rig, you found another use for all that excess heat — like, say, heating your entire home? Heaters are already one of the most expensive electrical devices in a home, and if you’re already spending the money to heat your home, you might as well make some of that back in cryptocurrency, right?
