Is a fun coin but a very stable and usable one. Many exchanges use it as a means to convert between alt coins
It is legitimate for this purpose only, transferring between exchanges and saving on fees. Besides that there really is not much use-case here but this is crypto and it has survived for 2 years beyond that. So if you want to feel secure you probably can while investing in Dogecoin because it is a coin that seemingly never dies, despite how much not development is going into it
