Just finished the book 21 Lessons by

I'm glad I waited until I was a few years down the rabbit hole to have read it.
Before reading it, I was hoping that it could be a short book to recommend to people to learn about bitcoin. I think that would work only if the reader is curious and actually explores their curiosities and has a tendency to go down, well, rabbit holes.
Though, I suppose, in the end, not everyone is going to go down the rabbit hole. And that's fine, it isn't realistic to expect everyone to do it.
If you're already down the rabbit hole, I recommend giving it a read. It's essentially 21 big concepts in brief.
