Unless they will burn more and more each year then yes 1$ might come this way.
In fact now Dogecoin is back at rock bottom as there is no very strong mining community in the Doge ecosystem. So it is very unlikely that Dogecoin can reach $20,000 in the next 5 years, moreover the totality of the volume is very large.
Yeah, if they do burn some doge supply already circulating, $1 figure is very decent for doge in the next 5 years.
