Dump $doge ? 
BTC= $100,000, when Doge =$1
BTC= 1 million, Doge= $10
I really doubt that it will happen though, I mean it's highly speculative. The price might increase with Elon Musk's help and influence towards the market but a 10 dollar? That's quite big for a memecoin with no utility to begin with, as even one dollar is already big for doge.
But it's your choice OP if you will bet and invest towards Dogecoin, who knows right? That speculation of yours might come true but you should know that the chances are much lesser than slim, to be honest.
