If DOGE had such a high price, it would've surpassed Bitcoin in terms of market cap. We all know this is impossible, since nothing can beat "The King". What makes you think a cryptocurrency with a high supply will ever reach $20k? Besides the fact that there are billions of DOGE in circulation, there's inflation built into the protocol itself (new DOGE are added every day without limits). People are out of their minds thinking they will strike it rich with a "meme" coin like Dogecoin. It's "fool's Gold" if you ask me.
The OP should focus on Bitcoin, since it's the one that holds promise to change our world for the better. All other crypto coins depend on BTC to survive, so without it, everything will simply fade away into oblivion. Who knows if DOGE goes back to being worth less than $0.01 after the hype ends? Just my thoughts
