Publishers Weekly gave The Age of Cryptocurrency a “starred” review; here’s what they had to say:

While many readers understandably have a hard time wrapping their heads around the concept of non-government-backed currency, journalists Casey (Che’s Afterlife) and Vigna, who blog about cryptocurrency at the Wall Street Journal’s MoneyBeat blog, here use their considerable expertise to make the Bitcoin phenomenon accessible.

They take a thorough, multidisciplinary approach to the topic, including a fascinating examination of the origin of money. The authors are appropriately cautious, warning that despite increased public awareness of Bitcoin, it remains a niche product, and the jury is still out on how far and how quickly it and other digital currency will spread.

However, newcomers will gain a better understanding of the revolutionary potential of digital currency, especially for the “roughly 2.5 billion people from Afghanistan to Africa to even America who have been shut out of the modern finance system.” And the explication of the non-currency applications of the concepts behind Bitcoin—such as tamper-proof records of verified information—will be valuable to any reader.
