Dogecoin has been around for ages, while similar to bitcoin in a lot of ways it's not nearly as useful as bitcoin and is nothing more than a joke currency. It will never amount to much, the huge supply will always limit that as well as the overall sentiment in the community.
I won't discourage any hodler to let go of his or her possession since dogecoin is similar to bitcoin. Anything is possible to happen from burning excess coin to adoption of cryptocurrency generally or dogecoin particularly, to political manipulations.
