First off, there is no global warming. At all. None.
Second, mining bitcoins takes a massive amount of energy, so much so that bitcoin mining companies have gone to northern Canada for cooling purposes.
Third, there was no evidence presented, no facts, no math, to state bitcoin was more energy efficient to process transactions.
This propaganda gets a flat F for a grade.
I think it was meant to respond to the climate alarmists who are making these claims.
Since their data is falsified, a high level is all that is needed.
Rather than discuss BTC in isolation... how does BTC energy usage compare to:
Banking
Airlines
Travel
Manufacturing
Mobile phone industry
The internet
Etc?
Of course the alarmists would like to do away with every capitalist industry anyway.
