This book is completely free for you to read online and will be so forever. There will be no ads, no tracking and no crypto mining in the browser.Some sites have replaced ads on their sites and instead use visitors’ computers to mine for them. A novel way to use cryptocurrencies but with questionable efficiency. Some do this without asking or notifying you which is definitely scammy. Therefore many adblockers block them outright.
When I some day finish the book and decide to release it in other formats I may charge for them, but the web version will always be free.
If you find the book interesting and want to show appreciation the best way is to share it with others.
