Dogecoin will never make a "comeback" because it is never going anywhere, it has always been one of the most popular coins and will keep being like that forever.
I know it is just a joke coin for many people but that joke coin has managed to out perform thousands of coins that actually started out as a good idea project. There are people who think they will solve some problems in the world with the coins they are making yet dogecoin being a joke coin has managed to be bigger than all of them.
At the end of the day, comeback could only be with price as people might imagine but the marketcap is already huge, the price is not because there are tons of dogecoins right now and the price could potentially go even lower with time (don't know how many doge will be in the end). So marketcap will go up, price sometimes goes up but eventually doesn't have that long term possibility.
Exactly. It's nearly impossible for Dogecoin to make a comeback, especially when its supply is highly inflationary. I believe that Dogecoin's value will decline over time, because of this factor. Right now, it's abandoned in development but somehow the community is still supporting it. This has kept DOGE alive for all these years. Compared to other altcoins, Dogecoin has been tried and tested over time. We've seen how some of the new altcoins have fallen over time. Most people have already forgotten about them, leaving such altcoins dead in the long run.
That's not been the case with Dogecoin, as it's still mined and used by people worldwide. It's odd to see a coin without any development or innovation, being actively used within the mainstream world. I guess people have found a love into Dogecoin, being extremely inexpensive and all. Still though, don't expect to use DOGE as a long term investment since prices decrease over time. You'll end up losing more money than what you've initially invested if you decide to do this. It's better to use Dogecoin in the short term for performing quick trades or sending micropayments at a fraction of the cost. If it ever makes a comeback (which I doubt it will), it would be as a result of a new development team taking charge of the project. Other than that, Dogecoin will remain as is for years to come. Just my thoughts
