RE:HOW MANY MINE DO WE NEED ? ( cobalt )Yeah, that was quite a story in Nov 2013 when musk started his gigafactory quest. Of course that was a decade ago.
Now we are in the pennies, Cobalt cost is low, and LFP has been declared the victor, much like betamax vs VHS.
Do we have one more rodeo in us? If you ride this bronco, don't get greedy. Ride it 20 and jump.
