Quality research and intriguing storytelling

This is quite a story. While it requires some in depth explanation of technologies, the heart of the book focuses on cyber crime investigations, the business and economic impact of crypto currency and a slew of interesting personalities.

Really enjoyable read on following cryptocurrency and how it happened
Format: Hardcover
Andy Greenberg is a GREAT storyteller and podcaster. Anything he writes is a must read. Tracers in the Dark was a super enjoyable, easy read. He covers, using people and stories, the basics of bitcoin and the people who try to follow the money to catch cybercriminals. I knew most (but not all) of the people and stories he covered, but Greenberg added a ton of detail I didn't know. He added timelines and color that fleshed out what happened, in each story and the overall timeline. It's a great, easy, read and I'm a better cybersecurity defender for having read it. Although don't read it for any super technical details. You're not going to learn the details of blockchain, bitcoin, or blockchain analysis...only how it's done, generally, and the people involved.

Entertaining and frightening
Format: Hardcover
Incredible job taking these real life stories and situations and writing them in such a captivating way that really draws the reader in. As fascinating as the forensic aspect of the dark web activities and investigations are, there were some very disturbing and dark areas that the book justifiably went at some readers may find very uncomfortable so just be ready for that
