It's a great history lesson in how Bitcoin started and gives much insight into how and why many of the decisions were made in the way it functions. I highly recommend checking it out.
Oh, by the way, are you looking for a decentralized exchange?

Does it give the true identity of Satoshi Nakamoto?
No :D
Loved this book!
Offers a lot of insight into the people who helped drive Bitcoin forward, the motivations of Satoshi, and background of Bitcoin.
Sadly, a lot of this is lost and forgotten by many new crypto users.
Is a great reminder of the long term potential of Bitcoin and decentralized money
Yeah, it's really neat to find out what part many of the people I've of heard about played in the early days. It will probably be required reading in schools someday ;)
Is it readable for ordinary people or only who is fluent in crypto?
Yes, I believe so. There is also an audio book that you can just listen to! :)
