Billy Markus, a software programmer, designed Dogecoin in about three hours. Dogecoin, in my opinion, is almost probably not a sound investment in any traditional definition of the term. It has an infinite supply, is junk, and has no utilities; all it has is a random hype that has been constructed around it, and all thanks to Elon Musk. It's a bubble that will explode with the force of the largest rugpull you can imagine. Keep away from it.
