Visa's underlying currency (fiat) uses *zero* energy (paper notes).

False, quite some energy and other ressources are required for minting/printing and distribution.

Childish pedantry. How much energy do you think is used to print a hundred dollar bill? You think the FED is doing J/$ calculations before they fire up their printing presses?
Hint: BTC miners *do* Cheesy

[Probably they would be better off doing some calculations, in several countries the smallest coins are more expensive to produce than their face value.]

Do you really think printing them is all you need?
E.g. You need to distribute them, offer the possibility to replace old banknotes after their life span and you need very high security in every single step.
It doesn't end there, just think about all the cash transports from companies to banks. Okey, that's fuel and working time instead of electricity, but those are valuable ressources, too.

See above, tell me i'm wrong Grin
