I think Dogecoin is still worth investing in. Even though we know that Doge's price has decreased significantly since reaching the ATH level. As we know that Dogecoin has experienced a significant increase in popularity, mainly due to the influence of Elon Musk.
Yes, for short-term investment, I don't think there is a problem, as long as it's not for the long term,
when you are profitable, sell it immediately and don't hold it,
the influence of Elon Musk is indeed extraordinary but it seems that Dogecoin is difficult to repeat the glory at that time.
