Book Review: Digital Is the Cash

“Digital is the Cash” is a short, accessible read, looking at cryptocurrency from a vaguely African perspective, with a strong preference for Dash.
“Understanding the Past, Present & Future of Finance in One Read,” boasts the subtitle of Digital is the Cash by Nathaniel Luz. Whether the book achieves this lofty aim is likely to depend on the readers feelings towards Dash (DASH) being the future of finance.You see, Luz is an ambassador for Dash Africa, and strongly believes that the cryptocurrency represents the future of money. His story is actually more interesting than that, as I discovered when I spoke to him, but potential readers should be warned that parts of this book read more like a press release.It should be noted that Dash did not fund the writing of the book, although it has paid for a print run of hard copies which are being distributed to libraries and institutions around the globe.Start at the beginningThe first topic that the book tackles is money: what it is, how it has developed, and the various forms it has taken. From bartering to commodity money, through cash in metal and paper forms, and finally to digital currency in both credit/debit card form and cryptocurrency.The writing style is accessible and enjoyable, with clear examples illustrating the concepts explained. The book would have benefited enormously from a decent editor, but once you get over the odd incongruous turn of phrase, the content is solid.Luz then turns his sights on the history of the global financial sector.

Blockchain technology underpins these advances in the financial industry.From overview to deep dive…At this point the book suffers from an abrupt change in style. Although the writing is still accessible, the content goes from an interesting overview to a quite technical examination of the next two topics.First we get a look at blockchain technology and cryptocurrency, but the chapter goes into a level of detail which perhaps starts to hint at its target audience. We learn about different consensus algorithms, types of wallet and addresses, and then get a guide to buying, receiving and owning cryptocurrency.It starts to feel a bit like a quick-start manual for those wanting to get into cryptocurrency for the first time. And in case there was any doubt as to which cryptocurrency the newbie reader should be getting into… we get to the chapter about Dash.… to sales brochureThis chapter is an unashamed trumpeting of the magnificence of all things Dash.
