Dogecoin has smaller marketcap than Bitcoin and Elon can not save Bitcoin from 50% drop. Don't wish that Elon can save Dogecoin with 50% drop or 200% drop. In addition, why do Elon have to save Dogecoin? Price crash will help him to buy cheaper Dogecoin and prepare for another tweet.

Elon is not responsible for fall of Bitcoin or Dogecoin. Price has to be fallen as natural price movement in any market. Bitcoin and Dogecoin would have not risen too much if Elon had not tweeted about them but they have to correct without Elon Musk.
