Dogecoin is created just for meme, there's no real correlation with charity or even promoting good will. If you're talking about how doge can be used for charity (sending money) then other crypto could do that aswell.
Not to mention the recent bullish due to Elon Musk, frankly is also motivated by sheer amount of greed. It's not like the people bought doge and then hold it for eternity, they also seeking profit you know?
I still have doubts about Dogecoin. It's embarrassing that real fame and popularity came to the coin only thanks to advertising from Mr. Musk and no significant reasons for such madness. But I am very interested in watching the current situation and curious how it will end.
