A high level overview of the world of Cryptocurrencies, liberally illustrated with Doge memes.
This was a lightning talk (5-7 minutes), so it scratches the surface, hopefully enough to get you interested in the world of cryptocoins.
It begins with the basic definitions, the reasons to use and accept cryptocurrency, the main currencies (Bitcoin, Litecoin, Dogecoin), the many altcoins and their distinguishing factors, and finally introduces you to cryptocoin mining (producing your own coins using your computer).
