Thanks for the feedback, and thanks for actually looking at the book!

I thought about making it an actual exercise instead of "extra credit", but doing all these exercises is a big ask for almost everybody that's not already deep into bitcoin/tech. I want to make this accessible. People struggle and get confused even on far simpler steps.

I should probably consider mentioning the "verify the software" step in the last section, when I talk about making a more permanent wallet (the one they work on in the book is meant as a temporary practice wallet, with small amounts).

Please let me know if you have more comments!
