Yes you read it Right there are several Cryptocurrencies which were created just for Fun or to have a GAG. In the Long Run, some of these Coins got some Huge Traction and Support from various Users and came to be Known to almost Everyone. DogeCoin is a good Example of this Point.
Jesus Coin
This is a Classic Example of a Joke Coin in which we find both Money and Religion Merged together. Apparently, the description on their Web page stated that Jesus Coin Holders will get their Sins Wiped. Isn't that just Funny as hell.
Useless Ethereum Token
This, in my Opinion, is the Most Funniest one of all. The Creator of this Token held an ICO in which he/she Blatantly said that he was going to use all the Money for Himself and any money you spent will lead to a Loss. Plus the Token Symbol is a Middle Finger.
DogeCoin
I don't think I need to explain how this Currency came into the Crypto Market and why it is still holding its Fort. Dogecoin is most certainly the king of joke coins. This widely known and well-loved coin was initially designed to have a Dog as a Meme Coin.
