Just some thoughts and I would like peoples opinions on them: Maybe BC shouldn't start a public smear campaign against BTC and its energy wastefulness until BC can stand completely on its own (until it is not heavily dependent on BTC like every alt is). At this point, anything that might hurt public perception of BTC would likely hurt all of crypto including BC. Also, and I think others have pointed this out before, if you are going to try and sell BC as energy efficient you better be prepared for people being critical of the hypocrisy that is the multipool. And if you consider the fact that BC was the altcoin which started the altcoin multipool fad... what is the real effect of BC on energy consumption? (I think one good counterargument for the "wastefulness" of the multipool is that the majority of BC miners would just be mining something else if it weren't for BC and in that sense it is not additional energy waste just redirected energy waste)
Valid points Storm. I think it will be in our best interests to ensure that any 'green' talk is kept as a positive for BC and not, as you put it, a smear campaign against BTC.
As for the multipool.. as long as their are PoW coins there will always be miners. The larger are multipool the faster energy efficient BC takes over. The multipool can very easily be seen as a tool that allows us to bring the crypto community towards energy efficiency even faster.
I agree, multipool only appears wasteful until you think about it in the context of crypto at which point it seems pretty clear that it is a good thing in the long run. It will be hard to be positive about BC's energy efficiency without poking at BTC a little since in order to most effectively convey BC's energy efficiency it needs to be compared to BTC's massive energy use. I think it just needs to be worded/approached correctly. Like you point out, focus on the positives of BC don't focus on the negatives of BTC anymore than you need to in order to distinguish BC from it and bring out the positives of BC.
