Well, first I congratulate you for doing such great work that will support many Bitcoin users. I saw the book that you have uploaded on your X account and read some part of it and what I decided is that you did wonderful work not only by writing it too well but also thby e interior when I saw was very attractive and good looking which give an additional and handsome look to your book. Through this book, I think many people who only know about Bitcoin invention in 2009 and after that,  will know about the history of Bitcoin how the idea of Bitcoin comes, and how it is made. Hope this book will bring some revolution in the Bitcoin ecosystem. Lastly I again appreciate your work and hope to grab what you want as support
