As a response to the ongoing Coldcard hack and other AI-related issues going on, I've decided to make Defending Bitcoin available entirely for free on https:// defendingbitcoin.com/reader It was always in the plan to create a sort of "reader companion", and I'll be adding more features to cross-link the contents of the book with useful information on how to improve your Bitcoin security. But, for now, the entire text of Defending Bitcoin is readable from your browser. AND we've finally added it to the Bitcoin Infinity Store at https:// bitcoininfinitystore.com, along with Max Hillebrand's Praxeology of Privacy (also freely available on Max's website). If you want to support either of us, you can now do so with Bitcoin. I also plan to update the chapter on AI Risks. I honestly hadn't anticipated quite how brutally AI attacks would hit, and, like most others, I certainly didn't expect one of the most widely-recommended hardware wallet manufacturers had simply neglected to implement such a fundamental feature as secure seed generation. In hindsight, I should have emphasized the risk of AI attack capabilities more strongly. I hope Defending Bitcoin can be useful to anyone looking to improve their Bitcoin security. Let me know what you think, and stay secure out there.
