Byva slusne odkazovat na material k diskusii, ktory nie je za paywallom.
Maju tam ale aspon odkaz na github s datami, a tam ma zaujala tato veta:

"Proportions in the adoption of technologies were converted to transactions assuming a global number of cashless transactions of 314,210,898,142 [WorldBank. Global Payment Systems Survey 2016. (Accessed February 28, 2018)]. At each time step, CO2e emissions for the given number of transactions were estimated based on the emissions generated to mine that number of transactions in 2017."

Co je samozrejme blbost, samotne cez btc tolko transakcii za rok urcite nepretecie, a pokial sa bude pouzivat nejaka nadstavba typu Lightning Network, tak pomer cena/transkacia bude uplne iny.

+ prepocitavat spotrebovanu energiu na CO2 v buducnosti je tricky bussiness, uz len preto ze by sa malo zlozenie vyrabanej energie menit.

(v tomto kontexte by si podobne tvrdenie mohol povedat aj o online reklame, ktora uplne zbytocne v sucasnosti mina radovo podobne mnozstva elektriny ako btc)


Ako spotreba PoW je problem, ale taketo clickbait clanky si nie som isty ci to pomahaju riesit.
