Both Sides of the Coin

Eric Balchunas, James Seyffart

Synopsis

Is cryptocurrency the answer to all our problems? Or, is it just funny money from space?

In Both Sides of the Coin, two of the world’s leading ETF analysts cut through the hype and hysteria to deliver a clear, grounded guide for everyday investors. From the downfall of FTX to the launch of the first bitcoin ETFs, this book traces the rise, crashes, and resilience of cryptocurrency.

Eric Balchunas and James Seyffart explain how ETFs have transformed crypto investing due to their low fees and diverse exposures. Discover what makes bitcoin unique, how it fits (or doesn’t) in a traditional portfolio, and whether it really can compete with gold as a store of value.

For anyone wondering whether to take the plunge into crypto, this is your essential roadmap.

Let's take a look at both sides of the coin.
