Whether your decide to continue to hold an alternative currency is supposed to be a personal choice and move after research and previously knowing where you are going to relocate that money for it in order to grow faster, or at least at a better place.
So, that being said, I am going to give you my personal opinion.
I think in the long term Dogecoin will continue to be a staple within the world of meme coin, it has proven to be a very good track record, it has a high volume and it is supported by all major exchanges. Dogecoin is a coin which is completely driven by the force of their community, so I would advice you to go and do some research on how the Dogecoin community feels and whether their are either encouraged or discouraged on the future of the project, whether they are looking for new projects to invest in or not, that kind of information is of a very big value to you. Just my two sats, obviously. Good luck.
