This is exactly the answer but an addition, Dogecoin for what I've experienced is one of the strong coin that exist until now, where you can use this? If you're going to take a look at the most exchange site Dogecoin is always there, If you play in most of the crypto gambling games Dogecoin is there and also there's a lot of services who accepts Dogecoin.

In bitcointalk you can use it as a mode of payment, you can also use dogecoin as a collateral the good thing about doge is that the price never reaches 0 and the project still exist today unlike other coins which trends for a mean time then disappear.
