If we could burn bitcoin apologists we would have infinite energy because you are the densest bunch I've ever met https://en.wikipedia.org/wiki/Climate_change

Damn, I knew the governments hated cryptocurrencies and will try to shut it down at some point, but I haven't realized there was such hostility towards it.

Question that came to mind after reading the headline: could this become a future reason for governments to criminalise the trading / use of Bitcoin because of negative environmental effects? On the surface it seems the value of Bitcoin is directly tied to its energy consumption and thus environmental harm. I get that Bitcoin itself is decentralised and cannot be banned outright. But could it be neutered in such a wa…

Criticism a about bitcoin power consumption betrays an understand of even elementary economics. Replace bitcoin with beanie baby, and one could have made a similar argument in the late 90s about beanie babies causing a fabric shortage or fabric being wasted on toys that could instead be used for better purposes. When the beanie baby market crashed, the problem effectively fixed itself, as there was this sudden glut o…

Was there a fabric shortage in the 90s?

From what I understand bitcoin currently has a $20+ transaction fee with a transaction time takes 60 minutes+ With these issues in addition to the high power consumption, how will Bitcoin become a usable currency?

that ship has sailed long ago. it is now seen as a replacement for gold and a hedge against inflation

Perhaps not all of it is entirely "wasted" though. I've largely been able to avoid heating this winter as a result of crypto mining. A computer pumping ~300W into the air 24/7 is remarkably effective for a small apartment

Electricity is one of the most inefficient ways to heat a dwelling. I think natural gas is still considered to be several times more efficient but I haven’t looked at it in a few years. Of course if you are also getting benefits from the crypto you mined that will offset the cost.

Electricity is 100% efficient in a resistance heater, in that all the electricity used is turned to heat. However, it is considerably more expensive per unit heat than natural gas, even though you may only get 70-90% efficiency with your boiler or furnace. A heat pump can be even more efficient, though. An electric heat pump can be more than 100% efficient, in that each watt of electricity can be used to move more than 1 watt of heat into your home using the heat pump.

This depends on what you’re measuring the efficiency with respect to though, right? Cost-wise, yeah, natural gas outperforms electricity everywhere I’m aware of. On a grid powered entirely by renewable energy though, there’s a meaningful sense in which the electrical method is “more efficient”

Can you successfully mine bitcoin with one computer these days?

I think you misspelled remarkably. It's actually spelled "terribly".

Genuine question: how much does this matter if much of it is renewables and cheap hydro? I feel like the negative externalities of using a lot of electricity are very very tied to where that electricity came from

According to their mining map[1], 35% of the global hashrate happens in Xinjiang. From Wikipedia, it looks like most major power stations in Xinjiang are coal driven[2]. 10% is in Sichuan, which appears to be largely hydro-driven[3]. 1: https://cbeci.org/mining_map 2: https://en.wikipedia.org/wiki/List_of_major_power_stations_i... 3: https://en.wikipedia.org/wiki/List_of_major_power_stations_i...

It seems [0] that roughly 40% of crypto mining uses renewables. Yesterday I wrote a lengthy post about the topic [1], if you're keen to know more.
