Unfortunately it’s still way, way less efficient than other heating systems like heat pumps This also doesn’t address the wasted materials and labor used to make the chips.

I dont think heat pumps work in sibearian winter of -40

F or C?

2008 - 0.00 USD/BTC

Come now, you are just bargaining. Just move on and get to the final stage of acceptance and hope.

What am I bargaining about again? I trade bitcoin options + the volatility has been great for my own positions. ¯\_(ツ)_/¯

Did you buy the top or something?

What other currency are people fanatic about HODL'ing? It's not a currency.

I don’t know about you but the concept of collecting US Dollars et al seems to me to have caught on

It’s generally not recommended to hold your wealth in dollars. You invest it. Currencies aren’t for holding, they’re for transacting.

Not really. Heat pumps can't be used in cold climates due to ice forming on heat fins which breaks the efficiency. It's why we use a lot of baseboard heaters in Canada. Bitcoin mining would be perfect for electric heating of homes here. Plus the added bonus of eliminating green house gas emissions from burning natural gas in a furnace (how my house is heated). The problem with baseboard is that gas heating is far che…

Define "cold". Mitsubishi units have 100% of capacity at 23F/-5C and 75% capacity at -13F/-25C:

They're used in Alaska:

Fujitsu says -15F/-25C as well:

The limits seems to be -25C/-15F, and I'm guessing that's because of the refrigerant that generally used in residential HVAC (R-410A?).

I guess I was trying to say its efficiency breaks down and isn't competitive with basic electric baseboard heat at some temperature below zero celcius (not sure what the break-even point is). I didn't think people in Alaska would be using that for home heating, is that a thing? The norm here is gas heat and the odd electric baseboard home which broken down elsewhere by another commenter is approximately 10x the price of gas heating.

And apparently Fujitsu's work better in F but the same in C. I always thought these were display-only settings.

It is useful if you consider having a non-governmental/internet native currency a useful thing. If you don't see any value in that, it's gonna be hard to justify that computation.

There are far less costly ways for the environment to achieve the same results. This is simply unjustifiable, when thousands of people are actively running the planet to the ground to make a quick buck in an online casino.

I'd love to know what your top alternative is

At the 'break down point' an air source heat pump (HP) is no worse than a baseboard heater: in both cases the COP is basically 1.0. So you might as well go with the HP as it'll be more efficient for probably the majority of the year.

You can get gas furnaces that are 'dual fuel': they'll run the HP refrigerant through the exchange and circulate the conditioned air, and once it's "too cold" switch to gas.

If you're going to buy a only-cooling AC unit, then spending a little more on a heat-cool HP is probably a smart idea. There's a payback period, and it depends on the price of your electricity and fossil fuel (NG, propane).
