Let me congratulate you on your great achievement in finishing this book after such a long time and great effort, and I would also like to congratulate you on publishing it on Amazon, it is truly worth it.
I remember when you first posted the thread about the book more than a year ago, I was impressed by the initial work of the book, although it was incomplete and lacked many additions, there must also have been many events during this year that deserved to be added to the book.
Completing such a huge book on the history of Bitcoin is a great work that is not easy at all, it may be one of the most important achievements of your life, congratulations.
I'm confident that the book will be appreciated by the community. Thank you for your praise.
