  • Overview
  • Engaging
  • Insider's Take


Gook luck to the layperson trying to make sense of bitcoin, cryptocurrencies and the blockchain. As banking and tech expert Igor Pejic notes, these topics elicit no shortage of both unfounded exuberance and reflexive fear. In this clearly presented overview, Pejic takes pains to deflate the hype while offering an even-handed analysis of the technology’s potential and risks.

Technophiles and technophobes alike will find this a useful and engaging read.
