Great video... can I add a couple things... 1. don't "invest" in vaporware. For instance, ethereum is an actual protocol, deployed into the world with people developing on top of it. So many of these other cryptos are just press releases. Maybe there's some alpha code, but past that there's nothing actually built. These could fall apart at any time.

and 2. store your coins on your own device. If you actually install the necessary applications to receive and store a cryptocurrency, it forces you to learn more about the tech, and also the skill, attention to user experience, etc. that the developers are putting into the project. Often times an idea sounds great, but the execution makes it worthless. Attempting to actually store a currency on your hard drive is a pretty good way of investigating that possibility.
