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?
So you still believe in Musk's opinion about environment friendly? I couldn't even believe that people were FUD by that stupid argument. Put that aside, electric cars are another story. When the whole world believe that electric cars are environment friendly then they are. Gasoline cars are obviously not friendly to the environment and electric cars (battery recycling) are not either, but point is electric cars are the better option.
