Startup idea: a cryptocurrency miner which also serves as a boiler. When you heat water, you mine cryptocurrencies.
@ploum you joke and yet i heard in Siberia they use mining rigs for heating.
@Gargron : well, it makes sense. I was only semi-joking ;-)
@ploumIt already exists, I read an article about servers/home heaters a few years ago.
@ploumI searched for articles and there were at least 2 startups in 2014/2015. Wonder if they still exist. And what about summer!
