Looking at Doge's price-history, it's relatively stable, and its inflationary nature prevents it from becoming an asset to invest in. The enduring popular meme also gives it some intrinsic value that other Cryptos don't have.
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.
