Layered Money: From Gold and Dollars to Bitcoin and Central Bank Digital Currencies by Nik Bhatia is one of the most popular books in the world of bitcoin. But it's much more than that. The first half of the book is a history of monetary systems. This sets the stage for a dive into the world of bitcoin, including what makes it special and how it differs from the currencies that preceded it. Finally, Layered Money takes the reader through current developments in the Bitcoin world and how central banks will likely respond to it with their own digital currencies. We are pleased to be joined by the author of Layered Money, Nik Bhatia.
