I was given this free review copy audio book at my request and have voluntarily left this review.
This was a decent, high level, overview of cryptocurrency. It was not that technical but gave a good 30,000 foot view of what cryptocurrency is. I’m not sure it provides enough info to actually get you started using blockchain, though. If you are looking for a quick “cliff notes” overview then I would recommend this book. If you ACTUALLY want to start using blockchain, you’ll need to do a LOT more research.
