Obviously I'm talking about electricity here. How do we have something like Bitcoin but then have electric heaters? Won't a Bitcoin miner produce the same amount of heat given the same electricity? You can use heat pumps for extra gains on either, right?
A Bitcoin miner is more expensive to produce and maintain, yes, but over its lifetime shouldn't it pay for itself? I guess it just seems silly that we have datacenters with cooling (which takes even more electricity), and then also heating for homes.
