Though, in the case of Dogecoin and other PoW meme coins, when we talk about added utilities, what would we mean with that exactly? I could understand it in the case of Shiba Inu, as it is a token within the ecosystem of Ethereum, but Dogecoin is just a proof of work coin which does not have further utility different from what it had when was first launched. Sure, there can be some soft-forks in place to improve fees of the network and compatibility with wallets and nodes, but in the end of the day it is not as if Dogecoin could enjoy of smart contracts as Ethereum does (without a hardcore).
If there is something which has improved about Dogecoin is its community, it has become more mature and approach at the same time that project as a meme, but also continue to keep in mind the financial repercussions of holding a significant amount of that coin in the long term.
