If you’re unfamiliar with the show, Last Week Tonight with John Oliver is great at making complex topics both humorous and easily digestible.

In the latest episode of his show, Oliver breaks down the convoluted topic of cryptocurrencies, allowing you to explain it to just about anyone … even people who have no clue what it is.

With the way this sector is evolving, this can be an important lesson for anyone interested in knowing more about the world of crypto (and those not wanting to hear it from that annoying guy in your office named Dan … seriously, shut up Dan).

The next time someone asks you to explain the intricacies of cryptocurrency, show them this video that begins with an explanation of Bitcoin (the most popular type), what the term “blockchain” means, what an Initial Coin Offering (ICO) is, and how all of these things could be seriously shaking up the financial/tech world in the years to come.
