why have to think about how much of energy needed by bitcoin, I care only when bitcoin is on higher price for selling and when bitcoin at lower price for buying, just thinking when have I buy and when have to sell of bitcoin.
Exactly. People themselves don't care one single bit about Bitcoin's energy consumption, because they use it how it benefits them. If something is useful, the 'negative' aspect associated with that suddenly doesn't matter anymore, and this goes up for Google's (and basically other large tech companies) insane datacenters as well. Do people care how much their datacenters consume in energy? Nope, because people use their services.
Those who complain about Bitcoin's energy consumtion are bitter individuals not seeing the value in Bitcoin. In other words, no coiner trash talk. These people were trash talking datacenters back in the early internet age as well. Give it time; no coiners will become addicted Bitcoiners eventually, and they'll shut up about Bitcoin's energy consumption.
