If Doge doesn't have real adoption like NFT of course it's very difficult to reach $20k even in 10 years, maybe the price range will be dominant below $1, especially with the presence of the Metaverse project which will become a competitor so that other coins sink.
Dogecoin, of course, will never have a price of $20,000. Even one thousand dollars this coin will never reach. Cryptocurrency is developing very quickly, and therefore more and more competitive types of it will appear. Here it is more appropriate to discuss whether this coin will reach the price of one dollar. I also doubt it. The hype around meme-coins is passing. Even if Elon Musk continues to support it with his tweets and other actions, involving Tesla in this, it will be very difficult for Dogecoin to approach one dollar in price.
