I know something about addiction so to me Bitcoin enthusiasts sound like alcoholics who justify their drinking by saying "many people drink and doctors say a little drinking is good for you so lay off me." The fact that I couldn't even criticize Bitcoin's energy usage on HN util Elon Musk came out against it reinforces my opinion that it's an addiction. I imagine Bitcoin is a game like poker with a bluffing and holding strategy. Bitcoin as it is currently played has many addicted to it without regard to disastrous environmental consequences.
