I don't think Dogecoin is overpriced, today's Doge price is $.02579, which is quite low with the current volume of DOGE. On the contrary, I think the current DOGE price is still underprice, because I believe DOGE will soon skyrocket to $1.
but why do you think it's going to rocket to $1 ?! in my opinion it is overpriced because it has no usage whatsoever, and it's network is slow compared to other tokens who are lower than Doge and they have more utility, so i think Doge is for sure overpriced.
