Dogecoin has not much prospect of development in the future, I just see that every year it has 1 or 2 times big pump. It is possible that it was listed on Binance, supported in terms of advertising thanks to tweets by Elon Musk and John McAfee. But now that altcoin is still falling, I choose a safer option than investing in ETH, ADA, BNB, ...
The positive comments from both Musk and McAfee may have brought the decision of Binance to list Dogecoin in the first place. But the reasons could vary, as crypto land is highly unpredictable. One thing for sure is that Dogecoin serves great as a cryptocurrency for performing quick trades and sending micropayments at a fraction of the cost. Maybe that's why there are still many exchanges supporting Dogecoin even after being abandoned in development for quite some time. Compared with other alternative cryptocurrencies on the market, Dogecoin seems to have something unique that's loved by many crypto enthusiasts worldwide. Even Ethereum's Vitalik Buterin seems to be quite optimistic about the same.
While it's unlikely that Dogecoin will reach higher prices in the future, it could reach the moon in terms of user adoption soon. People will begin to notice the true benefits of Dogecoin, making them join the cryptocurrency revolution. After all, Dogecoin is much easier to obtain than most cryptocurrencies on the market because of its inexpensive nature. It's never meant to be taken seriously, since it was created only for fun by the founders themselves.
Nonetheless, with McAfee sharing positive comments related to Dogecoin, we should experience a boost over it's mainstream adoption soon. Things will become better for the cryptocurrency as other popular celebrities embrace it every step of the way. Despite this, Dogecoin needs true development and innovation in order to reach new heights. Just my opinion

I have the same sentiments towards doge also. This is the altcoin I always go for whenever I need to transfer money from one exchange to another. And yes, this might be also the reason why even small exchanges list doge as it is one of the most common altcoins among exchanges, which you can trade easily. Even if the developments are at halt, still the use case of doge in trading and transferring purposes are still significant.
