In reply to the discussion: NYC is getting its own city coin in line with the incoming mayor's crypto hub vision [View all]Bernardo de La Paz
(59,595 posts)12. Come off it. You didn't bother looking up even basic facts and doing a little arithmetic
A desktop computer uses about 60-250 watts per hour, call it 0.2 kilowatts per hour on average. An ATM is basically a desktop computer, roughly, in terms of power. I suspect it uses less power than the average desktop computer.
There are 470,000 ATMs in the US. Multiply that by 1750 kwh per year (@0.2 kw/h) = 822,500,000 kwh per year = 0.822 TeraWattHours per year to run ATMs.
Compare that with bitcoin mining at 142 TeraWattHours per year and going up.
And you want to multiply that by 100 or some large number of city cryptocurrencies?
Making an ATM: it takes about 16,000 Kwh, all in (resource extraction, shipping, production), to make a car. An ATM would take a lot less. Imagine a stack of ATMs, maybe 20-30 to equal a car (5 x 2 x 2 or 3). Call it 20. So about 800 kwh per ATM.
They last, say, about 10 years each. Halve that and call it replacing them at 20% per year.
20% x 470,000 x 800 kwh = 75,2000,000 kwh = 0.075 Twh per year building ATMs. Compare again with 142 Twh per year.
And you want to eliminate 0.822 + 0.075 = 0.9 Twh per year and replace it with 142 Twh per year multiplied by a hundred city coins?
And you think that is greener.

Don't discard logic. That system would NOT go away if we switched completely to bitcoin

Armored cars? Seriously? Do the math on worldwide armored car energy. And see post 12

If every city has a "coin", it's a mess. And a waste of electricity in greenhouse world

You don't understand a bit if you say "why is anyone mining something that is completely made up?"

You are saying that giving a computer a complex math problem to solve is a valid method of exchange?

They are NOT mined to "create" scarcity. They ARE scarce, mathematically
