The increase in meme coin price is just because of the help from hype made by Elo Musk. Dogecoin has no strong fundamentals, so it is always very risky to invest in this coin.
I agree with that but Dogecoin has been there with being as is, as a meme coin even without Elon and hype before.
It's been preloved by the community for being what it is and the image did just became ugly when too many meme coins were made and after it has got the pump and attention done by Elon.
You can't expect to invest in this coin for the long term, it is not a safe investment.
They saw the pump and still think that there will be a better pump for it again but we don't know if some gains will be made again. But I reckon what you said, if it's for long term, better choose another one.
