Book on the blockchain, crypto 2.0, decentralized businesses

Here’s a book on the blockchain, crypto 2.0, and decentralized businesses. It’s focussed on Bitshares. It’s only 99 cents on Amazon. Good user reviews.

This book seems to be a marketing tool for bitshares. Counterparty and Omni (formerly Mastercoin) can do much of what this book is talking about. ColoredCoins can do a lot of it as well. In my opinion bitshares seems overly complex. Perhaps I’m wrong… What do you all think?
