Was a fan of Bitcoin, until found out about this.

Also the fact Bitcoin is essentially a pyramid scheme. Get more people into it to artificially inflate its value, take the profits, leave everyone else with diminished value, build it up again, get rich, repeat forever.

Crypto should be illegal.

Crypto IS usable as an alternative to regular card payments though. If it gets illegal - what do we have left for online payment? Bank system, which is very hard and illegal to use anonymously, and is subject to sanctions/seizures/whatever. There is cash by mail, which is not always feasible. GNU Taler looks interesting, but seems like it not implemented much yet.

Risky link click of the day

I always find these breakdowns to be a little bit disingenuous. Like, you could do this same analysis on the whole email system, or on the whole world wide banking system, including ATMs, or on the energy usage of all DNS queries or even on global ActivityPub activity, not to mention shopping on Amazon or browsing Facebook. People DO do these kinds of breakdowns on generative AI, for exactly the same reasons, and reach the same kinds of conclusions.

Having a global computer network is INCREDIBLY energy intensive, with a massive carbon footprint. It's not shocking that a given application of that network is energy intensive, with a massive carbon footprint. These kinds of analysis are put together by people who already don't like cryptocurrencies (for all kinds of reasons both valid and ridiculous) who then go cherry picking MORE reasons not to like them.

A better comparison would be energy utilized per user, in which case the energy requirements for Bitcoin are miles and miles ahead of what the average person produces using a computer in the same amount of time. Even a gamer, playing 4k 120fps ray traced games 12 hours a day would use a fraction of the energy of someone mining bitcoin.

Exactly, if we do a back of the napkin calculation:

Bitcoin

Users

There are 200 million bitcoin wallets, let’s be generous and say those are all owned by unique individuals.

Total energy consumption

Bitcoin used about 114 TWh in 2021[1]

Bitcoin currently uses about 150 TWh annually

Energy consumption per user

150 TWh / year 
————————— = 0,75 TWh / user / year
200 million users

Banking system

Users

There are over 8 billion people on the planet today, let’s assume 4 billion of them have access to the global banking system.

Total energy consumption

The global banking system used an estimated 264 TWh in 2021[1]

If we assume the same consumption increase rate for banking, that’s about 348 TWh/year currently.

Energy consumption per user

348 TWh / year 
————————— = 0,087 TWh / user / year
4.000 million users

With these numbers, bitcoin uses almost 10x the energy per user annually.

There are of course a myriad of things one can argue over whether it makes a fair comparison, none of which I feel like arguing, since this is just a really simple estimate with a lot of assumptions.

1: I used the numbers in this article uncritically, if you have better numbers you can run your own calculations.
