What is Crypto Currency?

I found these three basic videos from DASH explaining what is crypto currency and blockchain. This is a very basic explanation of what crypto currency is, how it works, why is valuable and why you might want to have some. The playlist in the end sells DASH, but these three videos are generic to crypto currency.

DASHย is a privacy-centric digital currency with instant transactions. I’m not endorsing DASH, I just wanted to share these three basic videos.
