Hey @belenguerra and thanks for your kind words. Honestly, I have gone out on a limb with this post and written more about crypto and blockchain than I'm capable to teach. I only did that as part of Achievement 4. So to be honest, I can't recommend any literature because we are also still learning and finding out how it all works. But there are a lot of nice and helpful professionals in the community who can give you qualified pieces of information. If you already made it here... I believe you are on the best way to success.
