First, it is ranked in the top 15 cryptocurrency. Secondly, it is so cheap that if it has a slight growth, you will make A LOT. Basically, right now it is not even worth $0.01. The potential in this coin is so huge.
Dogecoin has various use, but I wont list it.
This is my reasoning behind it anyway.
As always, invest at your OWN risk.
It had never worth up to $0.01. The price has refused to cross the $0.002-3 threshold. Now it's around number 20 on the list.
Anyway, I chose to invest in the Doges because it is structured along side the litecoin technology eventhough with a meme. Also, I like its cheap price and I am hopeful the price will push up after a while. I hold a considerable number unlike with other altcoins. Now, I wait in line for its surge so I can claim some millions in $$$.
