By October I expect the antminer S1 not to be profitable anymore. Just as much is spent on electricity as the value of generated bitcoins.
Another way to see it is that it generates
free heat.
40 EUR worth of free heat is generated in a month! It's pretty valuable! I will keep three of these running at home.
The rest I need to sell. But how? First the miner+ PSU + cables etc tak up a lot of space, Second it is ugly (not in my eyes, but in most people's). Third 99% of potential customers are unfamiliar with bitcoin, at least how to sell bitcoins into fiat. Still it would make sense to put antminers in basements etc where heat is needed to prevent water pipes from freezing and so on.
If everyone had the knowledge, I believe it would be easy to sell this "heater" for 120 EUR, but how... just how... can I convince people to buy antminers for heating?
