> Ok - but then you need to include all the exchanges and wallet developers etc. Yes indeed we should consider all factors. For Bitcoins we should count the number of active full-time people employed as miners and developers. I feel like the amount of people required to maintain a system should be counted in green efforts. Like for example bio supermarkets they provide you with products without packaging. Example you get your cereals from a giant glass container to your reusable container. Now that requires extra effort on handling/trasportation/refrigeration/storage. If all those things require a lot of more time we should consider the time of X people vs the saving in Y plastic or the saving in Z plastic. It might turn out that Bitcoin employees less/equal/more people time for transaction. People's time is very expensive.
