I do not think people will run away from bitcoin if it reaches $200,000. They'll be amazed how it could have done the impossible. Not even gold has reached that level in its history. I also disagree with you that there is something wrong with bitcoin if it reaches that price level, it is the contrary. But it is an impossible dream. It cannot even reach $1000 for the time being.
of course people wouldnt run away, a lot more would be investing into it because they would think that bitcoins will replace fiat soon
in my opinion i would be holding stronger than ever because that would be a really great trend up that would allow me to make money
