Dogecoin is the perhaps one of the most unique & captivating offering in crypto space. As of right now its hard to say for certain Wether or not dogecoin is dead. It is almost impossible to predict the future of crypto including doge. But, elon musk recently Said that he shall be working to make dogecoin is use in real world.
It has been considered a meme coin since it's inception, so there is nothing unique about it to be honest.
However, when we have individuals like Elon Musk pumping it, then it become one of the most valuable asset in the last couple of years and then investors jumping on the hype coin. Now for me, this is not a good coin to invest, in my opinion, it might not enjoy the support in the next bull run. Although it will still remain in the crypto space for the next coming years. So everything depends on how Elon Musk will market and used Dogecoin in the future. But for me, I'm done with it.
