As far as I can see, Bitcoin is not destroyed. It is still thriving, although the exchange rates have dipped below $50K. Elon should worry about his crappy Tesla EVs. From what I heard, a number of major automobile manufacturers are going to enter the EV sector in a big way. There will be more competition, and there is a chance that the overpriced Tesla cars will be destroyed soon by other manufacturers such as Toyota and Volkswagen.
