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?
You see in 2018 how much did Bitcoin and Dogecoin cost? and try to compare it with this year where Bitcoin got a new ATH in April and Dogecoin did too, this is a sign that if Dogecoin is at $20K, then Bitcoin and other coins will be 5X more expensive than they are now, hopefully you can understand from what I mean.
