Actually, I don't think that this news is capable of breaking the trend. When Elon Musk declared this, Doge grew up by 25%, but it seems to me that red market will continue. Elon Musk influence mostly meme coins, but he doesn't have such a big impact on other cryptocurrency. Actually, I will not get to know about this if you didn't write about this, so I think that there are many other people who don't know about this as well, so there will be no reactions from their side.
The reason of not being a popular coin that is known by everyone will not be the reason that doge will not increase in price but the reason will be that bitcoin itself is dropping and likewise other big coins so dogecoin that is regarded as meme can't just take the stage. If this happens, it means Elon musk will be regarded as Satoshi in the crypto space.
