Cryptocurrency by John James is a short 40-page read with a somewhat pretentious subtitle: The Complete Beginner’s Guide to Investing and Trading in Cryptocurrencies. Throughout the guide, the author is very careful and correct to encourage any potential investor and all readers of this guide to do careful research before investing or trading in cryptocurrencies. That is logical. The author then creates a further sense of legitimacy and validity to his advice by noting that careful research is a prerequisite for any type of investing. This means that this guide has little value beyond giving basic definitions to terms used in the cryptocurrency environment. A dictionary and an online search to assure dictionary definitions were not modified by technological jargon would accomplish almost the same thing as reading this guide. What new information does this guide bring to the table?
