Feel free to add some updated statistics and also a graphical presentation of what those millions of cards would look like, if you had them all together. We would circle the earth a couple of times, if we had all the cards that were manufactured, since it was introduced many years ago. Roll Eyes

Actually no!

The circumference of the earth is 40075 km, the card is 8.5 cm, so that would make around 470 millions cards to do one lap.

So, looking at some of the statistics and considering that those cards must be manufactured with the use of electricity and also destroyed and ending up in landfills, then I would say Bitcoin's carbon footprint must be minuscule compared to this industry.

Let's see you're comparing 149 million cards as a starting point with what?
13 million addresses in the chain with a balance of more than 10$? And that is global!
Let's compare the power consumption of all the bank in the world that serve billions with what? 400k transaction a day?

There are more ATM's and card readers out there, than all the ASIC miners ever manufactured and they use a lot more components to manufacture these devices. Wink

Of course, let's not count bitcoin atms, those are running on unicorns.

agreed
there are more PC's in banking skyscrappers, bank branches and data centres
more ATM's and merchant card readers

Coinbase has a nice office, binance also, so does bitstamp.
Oh wait, do they have servers and datacenters of their own? Oh wait, those run on carebears! Sorry!

You noticed that I gave statistics of 2014, because I have no updated statistics and the statistics was mostly for the US..... so take that with more updated statistics and extrapolate it to a global number with all the cards that has ever been manufactured and then let's travel around the globe with that.

Ok, let's also subtract the +/- 4,000 bitcoin ATMs https://news.bitcoin.com/bitcoin-atms-continue-to-spread-across-the-globe/ > from the approximately 3 million ATM units globally and see how strong your argument is. Roll Eyes

< Source : https://en.wikipedia.org/wiki/Automated_teller_machine > - We not even counting the millions of card readers merchants use globally to read those credit cards. Roll Eyes

There are currently only +/- 130 Bitcoin Exchanges in the World, compared to the 100 000s of Bank branches globally. "The US has slightly less than 8,000 banks/credit unions. For the rest of the world, you could estimate it by averaging 30 banks/credit unions per country, so for 220 countries/territories, that would be 6,600. So one could assume the figure would hover close to 14,600 +/- 1500 banks worldwide." - Wink

Some more interresting statistics :

The Agricultural Bank of China is the worlds largest Bank by a total number of employees, main office situated in Beijing in China and founded in 1951. This Bank has 441,144 employees, it has over 24,000 branches. Shocked

Let's not compare Bitcoin with it's competition, because there is no argument that they are wasting less energy and contribute less pollution than Bitcoin. Roll Eyes
