Cryptocurrency is a concept that goes from somewhat useful (Bitcoin) to just plain weird (Dogecoin), and now it goes a step further with the anonymous new cryptocurrency called Darkcoin. It acts similarly to Bitcoin, but its primary selling point is that Darkcoin is completely anonymous and difficult to trace.
Doge, the Internet meme of a grammatically-challenged Shiba Inu dog that prefers comic sans, is so popular that it has its own online currency called Dogecoin. The fact that Dogecoin exists may be news to you, but it's also news that Dogecoin is temporarily stopping its service after its database (the Doge Vault) was hacked.
