If I read only this sentence I understand that a bitcoin emits 195*29 more CO2 than an iPhone. But he got 195 by multiplying 29 by 6.7. And 6.7 is the ratio between bitcoin and Apple CO2 emissions. I'm not convinced that any of this computation is meaningful. We don't need this to prove that bitcoin is a waste of energy.
