Which textbook provides the best introduction to Bitcoin? Can you please nominate a proper textbook about Bitcoin that covers the cryptographic tools utilized in Bitcoin?
REGARDING TEXTBOOKS ONLY:

The best one is Bitcoin and Cryptocurrency Technologies by Narayanan &amp; Bonneau et al. 
You can get a draft version for free from Arvind Narayanan's blog.

The one by Andreas M. Antonopoulos, Mastering Bitcoin is good too. 

Roger Wattenhofer &amp; Christian Decker et al also wrote a nice one called "The Science of the Blockchain" about blockchains in general.
