Elon Musk influence on Dogecoins seems to have dropped, why ?
It dropped due to fud and other competition fud, many people used to believed that dogecoins was strongly backed up by Elon, unfortunately negative news and other different bad ideas poisoned the mindset of holders. Basically, that's a huge factor why this current situation begun to outburst in line with Bitcoin's huge fall from $60k down to nearly $30k starting 2022.
You don't need a FUD for Dogecoin's price to drop. It is enough for people to educate themselves and find out why the Dogecoin price was rising. Of course, Elon Musk was pumping up the DOGE price with his tweets about it. Whenever the price is pumped it has to drop eventually. It's just a natural process that happens with every coin or product that is hyped.
