that's a bitcoin transaction

i really dont have time. You can easily find what i try to say three tweets before... :P I cant answer the same thing to every "supporter" of this non tech guy. What kind of media is this? The blind-tech fest?

If you're trying to argue that the number of transactions per block is variable (I think that's what you're trying to argue? You're doing a terrible job of it) the point is that's is a *maximum* number of minimum-sized transactions, and you can use that to do the calculation.

you calculate transactions to bitcoin as a single input output this is wrong. Every AtM use 5520W. There are over 400,000 ATM to USA. That means that only in USA the ATM's uses 2428800000w

What exactly makes you think a single ATM uses 5520W? Here's an ATM datasheet. 260W idle, 410W during a transaction. http://www2.diebold.com/gssasupaes/cut_sheets/cut_sheet_files/Self%20service%20terminals%20-%20ATMs/BulkCash%20terminals/177443r02.pdf …

maybe i am wrong to this number i had not time to confirm it but even with 410w USA ATM for sure uses the same power as every house in develop world use or all of ATM's of USA use the same power as a small country. And we talk about one single country.

ATMs are an interesting case because they are one of the less efficient parts

if you consider solely point-of-sale transactions, traditional banking uses much less energy
