Dogecoin is one of the most traded cryptocurrencies right now, it has a really big community. But for investing, it is not the best choice in my view. Its price is almost stable or increasing very slowly since its creation, and I don't predict that it will go up highly at least in the nearest future.
Agree, dogecoin does look more stable and tends to have a slow increase but even so I believe dogecoin has good potential too when the bull run market as we can see in its history. So that way, investing in dogecoin for the long term might be a good option too because the potential of this old coin is very good to survive and grow over time.
