The Bitcoin CO₂ is some made up measure anyway, mining interest for a year isn't really attributable to the market cap of Bitcoin (they feed back on each other and so on, but there's no direct relationship).

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.

you're right, I reworded that incorrectly - now updated, thanks for spotting it!
