So you’ve heard about Bitcoin mining and you want to make money? To stay warm this winter, why not take what many miners around the world are trying to get rid of, their unwanted waste – heat – and use it for something good? Although this is not a new idea, there has always been a compromise between the powerful noise emitted by the miners and the heat it produced. We can use the enormous amounts of heat generated by computers that mines Bitcoin to provide heat to food plants growing under the same roof. This positive externality of the Bitcoin mining sector could help make it more energy efficient than the traditional banking sector while also making it environmentally friendly. Bitcoin rates and difficulty spikes can make the high energy bill and other mining overheads unsustainable by itself, but combined with other revenue-generating businesses using by-products from mining could be part of the solution.
