In the very forseeable future, dogecoin could actually surprise us! If futuristic enterpreneur like Elon is rooting for dogecoin, there is no telling the kind of improvement and devolopment that could happen to dogecoin. The possibilities of dogecoin been valuable is there. I guess everything depend on what the community and Elon do with it!
The more time passes in which there is not a reduction on the number of dogecoin ever created the more difficult it is going to be for it to pump, people see its low price and they think there is still a lot of upward potential when that is not the case as the number of coins that dogecoin has is massive, and while the support of Musk has been positive for dogecoin so far I cannot guarantee this is going to keep going to be the case as he is gaining a bad reputation especially with those that hold bitcoin for the long term.
