Hey there, great question!
There are a couple of outstanding books that helped me greatly to find my way through the cryptic and mysterious swamps of Bitcoin and ergo blockchain technology. I think,

Blockchain Revolution by Don and Alex Tapscott is the best book for blockchain space

Great book to get a thorough understanding of how blockchain is impacting a lot of different industries. This book is more business-oriented and showcases examples of how blockchain can change the business world. Good book, but for my taste sometimes somewhat too dry. But that’s just me.
