What is a bitcoin space heater?
Could you elaborate on the concept of a "bitcoin space heater" and explain its relevance, if any, in the cryptocurrency and finance landscape? I'm curious about the connection between cryptocurrency and this particular terminology, which seems unconventional at first glance. Are we referring to a literal device or is this a metaphorical reference to some aspect of bitcoin's functionality or market behavior? Clarifying this would help me understand the context and potential implications of this term.
