Dogecoin
What do you get when you mate a cryptocurrency with a meme?
Dogecoin.
Dogecoin represents a cryptocurrency (like Bitcoin or Ethereum), but it's based on an Internet meme. Specifically, it takes as its logo a Shiba Inu pooch featured in a once-popular "Doge" meme.
Dogecoin originally came about in 2013 as a joke, but it built up a following, to the point where it had a capitalization in the tens of millions of dollars within a few months of its founding.
