Preamble: Welcome to the Story of Money Podcast week here at RollingAlpha.com. We’re five episodes in – and so it felt like a good time to remind everyone to go and check it out. In particular, we’re desperate for your ratings and reviews. Thanks to everyone who’s given us feedback – it’ll help us improve things going forward. In this series of posts, I’m doing some selective highlights.

We tried to explain cryptocurrency.

Check it out. Episode 4.
