Why do i think Dogecoin can defeat BTC? it is not possible and nonsense with an altcoin that have no value at all and no use in real life, even until today, dogecoin is seem like a joke of developers to the world, created Dogecoin and left on its own, i totally disagree with the idea Dogecoin can be the next altcoin can replace BTC.
I also do not agree if Dogecoin becomes an altcoin that can replace bitcoin from which side of dogecoin has the advantage of being able to replace bitcoin I don't think there is an advantage over that coin for me bitcoin is the parent of all coins so I don't think biitcoin will ever be replaced
