So are you saying that all of his is lies?
"A single transaction of bitcoin has the same carbon footprint as 680,000 Visa transactions or 51,210 hours of watching YouTube, according to Cambridge’s Centre for Alternative Finances."
"A paper from 2018 from the Oak Ridge Institute in Ohio found that one dollar’s worth of bitcoin took 17 megajoules of energy, more than double the amount of energy it took to mine one dollar’s worth of copper, gold and platinum. Another study from the UK published last year said that computer power required to mine Bitcoin quadrupled in 2019 compared with the year before, and that mining has had an influence in prices in some power and utility markets."
“Bitcoin would not be able to fulfill its role as a secure, global value transfer and storage system without being costly to maintain,” reads a defense against bitcoin criticism from Ria Bhutoria, director of research at Fidelity Digital Assets."
"“Computers and smartphones have much larger carbon footprints than typewriters and telegraphs. Sometimes a technology is so revolutionary and important for humanity that society accepts the tradeoffs,” wrote investor Tyler Winklevoss on Twitter."
So even crypto advocates are admitting it has a giant ecological footprint. That's not too big a deal right now while crypto is a fringe currency that's barely circulated compared to fiat dollars, but if it becomes dominant, then what? Why not address a really serious question?
Yes. Even the stupidity of someone saying a bitcoin transaction has the same carbon footprint as 680,000 Visa transactions should give you pause. For one it means absolutely nothing since most power centers are using renewables and not burning carbon. Secondly because that math should give you serious pause when thinking about magnitude. Visa processes trillions of transactions in a year - think about what you're purporting to be true. If bitcoin is THAT disastrous you should be mapping block chain energy use to electrical activity and price surges. It would then be simple to find out how much it is destroying the environment. None of these arguments show actual environmental impact, just lazy math that on paper makes it seem like a big deal. I could make the argument that toasting bread uses up 17 watts of energy, or 2000 times more energy than boiling water. Therefore, toasting bread has a larger carbon footprint and thus is environmentally more destructive than boiling water - breakfast is bad.
There are several issues with the technology and scale that people seem to keep skipping over.
1.) Bitcoin mining and bitcoin transactions to secure the network are not the same thing. Mining activity is not what it was 10 years ago and most people do not mine bitcoin. THAT is the most power intensive process and it is concentrated in a few places. No one is feeling the effects of bitcoin mining because electricity prices have yet to spike nor do most of us live in China where most mining occurs.
2.) If you want to measure the impact of bitcoin energy use you would compare it to the energy used by to secure fiat transactions. This is much more difficult and takes a bit of imagination to even get them normalized because block chain transactions are "slower" than fiat networks in terms of transaction speed but almost always quicker to confirm. Of course there is also that little problem that the global digital fiat system is much, much larger than the bitcoin block chain and is using up far more energy.
3.) People have been railing about bitcoin (specifically block chain technology) being an ecological disaster for over a decade. Even with mining activity being more concentrated than before, it seems these people miss out that many miners use renewable energies and are located in cheap electrical price areas. Years ago there was a legit debate about American mining groups looking to Indiana iirc because the electrical prices are cheap compared to most places. Other than that, most of these discussions about bitcoin being some ecological disaster are boogie man arguments. Might as well shut down all of our digital payment systems. The only argument that is sensible is that bitcoin isn't purely a P2P system and has become a gambling machine that is harming others with no ability to centralize control.
4.) Bitcoin DOES have an issue with what ASICS chasing has done to the computer chip market. Shortages are everywhere and this is partially due to competition between miners. This is good and bad but overall its skewed demand for chips and that's why PS5s take forever to produce. There is lots of bytching about this and what its done to the price of dedicated GPUs.
Overall while there is legit concern about what block chain competition has done to chip markets, the environmental impact is overblown. Someone living in most parts of the USA feels little effect on energy prices because of bitcoin mining. Nor should they really care.
