If it is just a coincidence or not, the thing here is that most of the altcoins including are increasing when it comes to the price. But of course, news and social media infos can somehow contribute to the particular coin like dogecoin especially when it is indeed a good news. However, let us not forget that we shouldn't be fall for any fud , it may be a trap to the investors to buy more before the dump.
The uptrend of this market in recent days has led all altcoins to recover very well and dogecoin is among them. I think the price hike is really normal and there is not any news that makes this coin especially interesting for whales. Personally, I have tracked a lot of fluctuations in this coin and just choose the right time to invest, you can easily earn good profits from Dogecoin.
