imma go ahead and say it, it is impossible for Doge to reach $20k not just in 5 years, Doge just can't make it that far, there is just no way, its marketcap would be unbelievably high, it's just a meme coin, people can try to make some profit out of it and sell, it has no other rational usages.
It would be illogical to hit $20K in five years for Dogecoin, because if Dogecoin could reach that much, then everything else would be five times that price, so obviously this is too far to go and very unlikely to materialize unless the supply of Dogecoin is limited 100 units only and the people who like it can be very much.
I have been reading your statement a couple of times now but it seems I can't understand what you are trying to say. Why would everything else be 5x higher if Dogecoin ever hit $20k? Apart from the fact that Dogecoin will never hit that price, why do you say it is 5x for everything else by then?
