Not necessarily. Dogecoin has no fixed cap on the amount of Đ in existence. Rather, it expands at a rate of Đ5billion/yr, much to the chagrin of several currency pumpers.
I'd like the coin to take off as an actual currency, and of the coins I've looked at, I think it has the most potential for adoption in that respect.
But I don't think it's got the ecosystem to support that right now. A metamask-style doge wallet would do wonders for this.
Also, knowing little to nothing about the backend (or other crypto backends, tbh), other than that it's derived from Bitcoin - I have concerns about scalability wrt transaction settlement times, power consumption, and ease-of-entry with self-hosted wallets.
