Elon Musk talked about how BTC mining with electricity isn't environment friendly but he invented electric cars, in near future if this actually becomes popular electric cars will be available world wide and billions of vehicles will be charged by electricity so how is this environment friendly?
By comparison, it's obviously a waste of electric cars. And I'm sure when Elon Musk reported that the bitcoin mining environment was so wasteful of electricity it was wrong. I see from the data scattered news cryptocurrency electricity usage on mining is not the highest. I think he wants to take advantage to buy under. and now no one believes in what he tweets.
