This is a good start indeed.
Many traders "buy the rumors" and "sell the news" and don't care much how true will these rumors prove to be as long as they get to earn a quick buck.
Elon knows all this and therefore knows how to feed them with the rumors they want to hear so the TSLA bubble stays inflated.

I've said already that Tesla is a over-hyped auto-maker wannabe. As long as they earn more from green certificates and Bitcoin than from building and selling cars I cannot rank them as proper automaker.
If they will come with a proper breakthrough, if they invent a much better (and also cheap enough) battery, then they'll have my praise. But not before. Not for rumors.
