I don't consider Dogecoin as a coin for long-term investment and a great future. This coin was created as a joke, or at least it got such a reputation... that's why after so many years it's still a very weak coin. It's my personal opinion.
And that reputation with be forever but dont be the main reason to go out...
Doge is corrently at rank 50 in marketcap, so it alredy very very good.... my opinion :$
