If you're using resistive heating, a computer is about as efficient as a space heater. I have not recently done the math, but I'm pretty sure in my area its still more economically efficient to heat my home with natural gas than resistive heat. Obviously, emissions are a concern, future price uncertainty of fossil fuels, etc. Not the best way forward. However, heat pumps in my area can make a ton of sense. They're fa…

Can you elaborate? I've seen products that do this, it must be possible.

Resistive heaters use energy to create heat. Heat pumps use energy to move heat. For a resistive heater, its taking 1 energy unit from the wall and putting 1 energy unit into the air. A heat pump will use one unit of energy from the wall to take 3-5 units of energy from one side of the system and dump that 3-5 units of energy to the other side of the system.

I see. Heat pumps must move existing heat from somewhere though. Won't those come from burning fuels?

I have a lot of solar panels in my home. I'm generating more energy than I'm using. I don't consider efficiency to be a significant concern at the moment.

Of course it does. It also has better uses than say gaming, so if that is the logic maybe that should be banned, too.

There is a difference between the two. That's like comparing the fuel use or exhaust of a Fiat 500 to that of a cargo ship.

Under your analogy we shouldn't regulate car exhausts before we regulate cargo ships. At any rate, article says 250k mining devices there so the electricity usage is likely more from mining but not orders of magnitude more, and even if it was it would suggest they are not banned because of how useful it is (arguably gaming is even less useful) but because of size. But sure compare to gaming + TVs then.

I wonder if cryptominers in poorer countries speed up the buildout of more stable and robust electricity networks in the long run? I understand they sometimes stress it too much in the short run such as here and then the regulators have to take action but the interplay on a longer timescale would be interesting to see.

You could say the same about whether bridges to nowhere generate important economic robustness. The problem with this view is it ignores that such activity crowds out the ability to do something actually useful with the same resources, while also producing all the same externalities (both positive and negative).

You're talking about the broken window fallacy. I don't think it's immediately clear that a more robust and stable electricity network wouldn't lead to additional economical and societal benefits thus making it a positive sum game?

And so it begins. In the developed world in particular, we're seeing the move away from fossil-fuel power. This is good but currently relatively expensive. Crypto mining is starting to have very real impact on the ability of other people to live. It is adversely and disproportionately affecting poor people (who pay a greater share of their income for power). And at best crypto provides extremely limited utility for s…

> And at best crypto provides extremely limited utility for society. This is true for bitcoin . It failed at everything it set out to be and yet it is the most mined coin. Truly a waste of energy. There are better projects out there which actually provide value and utility. Monero is an example. It's pretty sad that bitcoin is still number one despite the existence of these projects.

>yet it is the most mined coin

Not a surprise when it is the most valuable one, a day of drops and the corresponding surges that come afterwards can set you up for a long time if you're not from the EU/US, it also appreciates faster than a house, which makes it a great asset to hold.

Not a surprise it is the most sought after, looking at it from the supply/demand aspect.

Crypto miners are pretty inefficient at heating your home. A heat pump is more than twice as efficient as direct heat.

Maybe so, but they generate crypto, which heat pumps don’t.

To say it generates no value is a misstatement. Proof of Work offers some value, it is just consumimg too much.

Think about as providing some form of uncensorsable money, eg for orgs like Wikileakd, Tor Project, etc.

The general public doesn't have the best grasp on crypto to begin with. If it starts messing with their ability to go about their daily lives with consistently available electricity at inflated prices then mining in those impacted areas may die a quick political death. Or have their facilities burned down by mobs that need those fires to keep them warm.

> Crypto-mining apologists will point to figures that say "crypto-mining uses mostly renewable energy". Which is a shit take anyway because that means that non-renewable energy (plus the renewable energy non-consumed by the miners) is now more expensive for everyone else, it's the basic law of supply and demand. And in the process those miners are also making non-renewable energy a more desirable investment because i…

It's sad that this gets downvoted because you're not wrong eg [1][2][3].
